The Mentor Automotive Refrigerant Identifier is designed to maximize automotive AC system refrigerant servicing and maintenance. Mentor accurately analyzes R1234yf and R134a with proven NDIR (Non-Dispersive Infrared) technology for the identification of refrigerant gases in automotive air-conditioning systems. Mentor has been developed with 30 years of experience in the production of safety critical gas analysis systems and recognized globally as the best the market can offer for accuracy and quality.


The Mentor refrigerant identifier plays an important role in helping to protect automotive air conditioning systems and service and recovery equipment from potential damage caused by the potential, and unknowing use of illegal refrigerants. The recovery of contaminated refrigerant can damage expensive service and recovery equipment, potentially leading to expensive repair bills or even scrappage. Mentor will prevent contamination of your refrigerant supply from illegal contaminants from refrigerant cylinders and customer vehicles, therefore stopping cross contamination of other vehicles with these illegal contaminants.
