The INFICON TEK-Mate Refrigerant Leak Detector 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.
The heated diode sensor tip automatically adjusts to any refrigerant and is thus equally sensitive to R12, R22, and R134a.Any airborne refrigerant activates an audible alarm which changes frequency with the strength of the signal.Sensitive to leaks under any conditions, including humid or wet.This leak detector meets and exceeds all standards of the industry, including SAE J1627 for R12, R22 and R134a.TEK-Mate� operates easily with a three position selector switch (off, low sensitivity, high sensitivity) and a battery life LED indicator.Operating temperature range: -20 deg F to +122 deg F (-27 deg C to +50 degC).Probe: Chrome-plated flexible metal, approximately 17" long.
