TEK-Mate is the ideal refrigerant leak detector for the user who demands reliable leak detection with a GREAT price.
Features such as the patented INFICON heated diode
sensor, variable intensity audible and visual alarms and automatic
compensation for changing background refrigerant
concentrations make TEK-Mate the best bargain in refrigerant
See for yourself why TEK-Mate is the #1 selling refrigerant
leak detector in the HVAC/R market.
Moderately priced, portable leak detector with proven heated-diode sensor technology. The electrochemical heated- diode sensor resists dirt, water, oil, and other contaminants offering exceptional resistance to the effects of contamination.
Inficon TEK-Mate Refrigerant AC Gas Leak Detector 705-202-G1 incorporates an electrochemical sensor consisting of a ceramic substrate, doped with a reactive element, and maintained at high temperature by a built-in heating element.
When a halogen-bearing gas contacts with the hot surface, the chlorine, fluorine, or bromine atoms are separated from the molecule and ionized. This causes an electrical current to flow within the ceramic to a collection electrode at the center.
Careful selection and application of the ceramic permits the INFICON sensor to provide similar responses to CFCs (such as R11 and R12), HCFCs (such as R22 and R123), HFCs (such as R134a) as well as replacement blends (such as R404A and R410A) so that the operator need not determine the refrigerant in use, nor remember to set a selector switch.
Furthermore, when searching for HFCs, the instrument does not have an exaggerated response to traces of chlorine bearing vapors which are frequently present.
