You are looking at a brand new Type K thermocouple, Temperature Sensor, Tool Park for DMM and Lab Instruments. This is a K type thermocouple, with 3 feet insulated wire and K type mini plug, with 2-flat-pin mini plugs. If you do not know what this is for, this item is not likely for you. This sensor goes with any equipment that takes K type thermocouple input, including clamp meter or multimeter. HVAC folks: its easier if you have 2 of the thermocouples when you are out taking system sub-cool and super-heat. one for each line, just switch at the plug. No waiting to switch the sensor tip location from line to line and wait for the temperature to get steady. take booth temperatures to save you valuable time(at least 10 minutes!). We have the thermocouple with a pipe clamp, look for model CT9 in my stores. WE DO NOT SELL ANY THING THAT is supposed TO WORK, WE SELL EVERY THING GUARANTEED TO WORK!
