Do you really know what you’re taking out of your customer’s vehicles?

The Mentor Automotive Refrigerant Identifiers provide simple and accurate refrigerant analysis to determine refrigerant purity in vehicle air conditioning systems and refrigerant cylinders. The Mentor is a user-friendly, cost effective R1234yf and R134a refrigerant purity analyser designed with state-of-the-art non-dispersive infrared (NDIR) technology.


The Mentor has been developed with over 30 years of experience in the design and production of safety critical gas analysis systems recognised globally as the best in the market for accuracy and quality.


If you service a lot of different vehicles a/c systems, chances are you’ll encounter many different kinds of refrigerant. You only have to look on eBay or Amazon to see the different types of refrigerants and mixes car owners and workshops can buy, and some of these are illegal or counterfeits which both eBay and Amazon are trying to stop.


Nevertheless, mixing these refrigerants can be extremely dangerous, as even a little bit of cross contamination can damage a vehicle’s a/c system, and also cause untold amounts of damage to expensive refrigerant recovery machines The Mentor identifier stops this from happening by letting you know exactly what refrigerants or contaminants are in the vehicle system or recovery machine.
