Jason Gargo –
Das Tesmen TBF-300 kommt in kleinen Karton an. Darin befindet sich das eigentliche Gerät in einer kleinen Aufbewahrungstasche sowie eine kleine Bedienungsanleitung in sechs Sprachen. Zwei für den Bettrieb notwendige AAA (Micro) Batterien (Markenbatterien!) liegen dem Gerät ebenfalls bei und müssen nur noch eingelegt werden. Dazu muß man allerdings den rückseitigen Deckel mittels eines kleinen Schraubendrehers mit Kreuzschlitz öffnen.
Für die korrekte Ermittlung des Wassergehalts in der Bremsflüssigkeit sollte man zuerst wissen, welchen Typ von Bremsflüssigkeit im Fahrzeug eingefüllt ist. Das Gerät ist geeignet für DOT 3, DOT 4 und DOT 5.1. Die Ergebnisse differieren hier zwar nur wenig, allerdings sind die hygroskopischen Eigenschaften der verschiedenen Flüssigkeiten unterschiedlich, ebenso die Siedepunkte! Für DOT 5 (silikonbasierend) ist das Gerät nicht geeignet!
Ich habe zum Testen zwei Autos zur Verfügung, bei beiden weiß ich die DOT-Nummer leider nicht, laut Werkstatt ist die Verwendung von DOT 3 und DOT 4 möglich. Zur Sicherheit habe ich für den Test immer alle drei Varianten durchgetestet.
Die Bedienung ist recht einfach, trotzdem sollten einige Dinge beachtet werden! Das erste Ergebnis ist NICHT verwendbar, es dient nur der Funktionsprüfung des Gerätes! Dazu taucht man die Spitze des Schwanenhalses in die Bremsflüssigkeit, das Gerät zeigt dann einen Wert von 2,2-2,4 (bei mir 2,3) an, der Bildschirm wird gelb und ein Warnton ertönt. Nach diesem ersten Test ist das Gerät für eine korrekte Messung bereit.
Beim ersten Versuch versuchte ich, nur die beiden Metallspitzen in die Flüssigkeit einzutauchen, das Gerät zeigte mit einen recht hohen Wert an und gab ein Warnsignal aus. Da die Bremsflüssigkeit nicht so alt war, konnte ich mir das Ergebnis nicht erklären. Ich wiederholte die Messung nochmal und tauchte die Spitze bis zum Ende der Verdickung in die Flüssigkeit ein. Nun war das Ergebnis in Ordnung, je nach eingestelltem DOT-Wert lag das Ergebnis bei 1-4-1,6% und damit noch im “Good”-Bereich
Beim zweiten Fahrzeug ist die Bremsflüssigkeit vor ca. 5 Jahren das letzte Mal getauscht worden. Beim Eintauchen zeigte das Gerät zwischen 2,2 und 2,5% je nach DOT-Wert an, der Bildschirm wurde gelb und ein Warnton ertönte. Hier sollte die Bremsflüssigkeit in nächster Zeit getauscht werden. Wäre der Wassergehalt über 3% würde sich das Display rot färben, die Bremsflüssigkeit sollte dann umgehend gewechselt werden.
Die Bedienung ist recht einfach, das Gerät kann über drei Tasten bedient werden. Mit der Roten Taste wird das Gerät Ein- und Ausgeschaltet, nach ein paar Minuten ohne Bedienung schaltet sich das Gerät aber auch von selbst ab.
Mit der F-Taste wird zwischen den drei DOT-Werten gewechselt, die H-Taste ist zum Zwischenspeichern des Wertes gedacht, wenn man den Meßwert bauartbedingt nicht sofort ablesen kann. Drückt man länger auf die H-Taste schaltet sich im Grundgerät neben dem Schwanenhals eingebaut, eine kleine LED als kleine Beleuchtung ein. So kann man sich sogar in der Dunkelheit im Motorraum zurechtfinden. Das Ablesen des Displays ist durch die Hintergrundbeleuchtung in jedem Umgebungslicht möglich.
Nach dem Test sollte man die Sonde mit einem Papier- oder Stoff-Tuch penibelst säubern und trocknen, damit das nächste Ergebnis nicht verfälscht wird.
Fazit:
Kleines und leicht zu bedienbares Gerät mit einem präzisen und mittels Bildschirmfarbe und Warnton sicher einzuschätzendem Ergebnis. Empfehlenswert gleichsam für Laien, Hobbyschrauber und kleine Werkstätten. Der zur Zeit berechnete Preis von rund 19,-€ ist für das Gerät, die Funktions und die Verarbeitung sehr günstig, daher gibt es von mir auch die vollen 5 Sterne.
Jason Bourne –
My neighbor friend calls on me to fix things for her, and to keep her from getting ripped off by car shops and other contractors. She was recently told that her brake fluid was bad, and I had no way to prove or disprove the shop, so I ordered this.
I was surprised to find how inexpensive this potentially lifesaving tool is, as well as how easy it is to use. Brake fluid is hygroscopic, which means it’s constantly trying to absorb moisture. When it reaches 3 or 4 percent, that’s enough to degrade the fluid to a dangerous level and cause your brakes not to work as well.
This comes with a manual, but I’ll spare you some reading. Pop the two included AA batteries in the back. Push the red button to turn it on. Push the F (function) button until your fluid is illuminated (check your owner’s manual or the top of the reservoir cap for Dot 3, 4, or 5.1 and choose that setting). Submerge the two metal probes into the master cylinder reservoir. The rest is automatic.
In a couple of seconds, you will see the percentage of moisture in your brake fluid and a clear indication of whether it’s good, or bad and needs changing.
The only thing this is missing is that it doesn’t test for copper, which is a fairly new ‘thing’ with brake fluid. In my mind, it’s not nearly as dangerous as water in your fluid, but it would be nice if this tested for it.
I prefer this model over the cheap-o pen models because this one –
+ has a gooseneck, making it easy to see when the two metal probes are submerged.
+ has a large, easy-to-read, fully lit LCD screen.
+ tells you the exact percentage of moisture instead of a tiny light.
+ lights up either green, yellow, or red to say good, caution, or bad fluid.
+ feels like a real test instrument, instead of a toy.
+ comes with a decent carrying case, although my zipper was/is messed up. (-1 star)
+ is about the price of lunch.
I feel much better about having this tool, and so far, it seems to be working flawlessly.
I hope this helps.

Ottimo tool.
La sonda metallica a collo d’oca flessibile rende l’uso estremamente pratico anche in spazi stretti e l’ampio display con funzione di mantenimento dei dati semplifica la lettura e l’interpretazione del risultato.
Fondamentale sottolineare che il liquido freni è altamente corrosivo: questo strumento aiuta a controllarlo senza versamenti o rischi, ma è comunque importante fare attenzione a non farlo fuoriuscire. La misurazione strumentale resta l’unico modo davvero affidabile per verificarne lo stato, perché l’aspetto visivo spesso inganna: un liquido può sembrare pulito ma avere comunque un alto contenuto d’acqua e compromettere la frenata.
Ottima anche la torcia integrata, utile in condizioni di scarsa illuminazione, e il supporto ai liquidi DOT3, DOT4 e DOT5.1. Testato su una vecchia moto ferma da tempo ha dato valori in linea con le aspetattive.
Aggiungo che il prezzo è onesto per uno strumento così ben fatto e completo: arrivano anche le batterie, il manuale e una custodia, ideale per proteggere la sonda e conservarlo in ordine.
In sintesi: preciso, robusto, facile da usare. Un acquisto consigliato sia per appassionati che per officine.

Works great. Fast results , surprisingly how quickly brake fluid goes bad

In the interest of full disclosure, as a trusted and unbiased Amazon reviewer, I was able to request this product free of charge, except for having to pay tax on its fair market value.
Good product which works as advertised. I consider this to be cheap insurance. I’m a bit of a gear head and from what I understand brake fluid should be changed every 2 years regardless of mileage. This tool will let you know the status of your brake fluid by measuring moisture content and serves as an analytical method of determining if the fluid needs to be replaced.
There are a number of devices on the market like this one. I suspect they all use the same or very similar sensing technology. The difference is in the physical design, perhaps the durability of the sensing wand, and alert features. This one has both visual and audio alerts as well as a moisture percentage display. For audio, the beat frequency is different depending on the condition of the brake fluid and the display also changes colr to alert you appropriately. The flexible wand appears to be very sturdy and holds its position but is easy to bend.
This is a useful compact device which is very easy to use and has a clean physical design. It also includes a zippered storage case and 2 AAA batteries. I’m glad it is not rechargeable as eventually lithium batteries fail and then a device becomes a throw away.

Works great, need to let it set in fluid for a few seconds

A hand held brake fluid tester for Dot 3, Dot 4 and Dot 5.1 fluid testing.
Brake fluid absorbs moisture over time which if the moisture level gets too high can lead to to fluid boiling under hard braking and consequent brake fade.
Manufacturers recommend changing the fluid every couple of years to avoid this.
This tester allows you to check on the condition of your brake fluid and allow you to decide if a change is due.
Simple to use, the tester comes with a good instruction manual. It has a flexible stem with a probe on the end that is inserted into the fluid.
It includes a calibration check which involves pushing the probe onto the two test points on the top of the machine.
In addition; there is a light on the top of the tester so you can see where the probe is in the fluid. The tester will power off after a set time if not being used.
It comes with a padded zip storage bag and Duracell batteries.
I found it easy to use and a valuable tool to have in my workshop.
