The Tek-Mate is a handheld leak detector incorporating electrochemical sensor ideal for CFCs, HCFCs and HFCs. Offering handheld convenience, the Tek-Mate leak detector boasts proven heated diode sensor technology. The Tek-Mate 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 ionised. This causes an electrical current to flow within the ceramic to a collection electrode at the centre.

Careful selection and application of the ceramic permits the Tek-Mate 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 does not need to determine the refrigerant in use, or remember to set a selector switch.

The latest version of the Tek-Mate features a soft touch operational pad, allowing the user to control the unit with only one hand. Switching the unit on or off and selecting detection levels (high/low) is done with a quick press of a button.

Packaged in a durable plastic case, the Tek-Mate leak detector is well above its class as a cost effective tool.
