Fieldpiece Instruments ATWB1 K-Type Wet Bulb Thermocouple w/ Alligator Clip, Type K, -50-150 °F, Wet Bulb Sock, K-Type Thermocouple, Mini Plug, ± 4°F (-50-150°F), ± 1°F (After Field Calibration, 32-176°F), Nickel Chromium/Nickel Aluminum (Conductors), Yellow

The ATWB1,Type-K wet bulb thermocouple can clip to HVAC/R equipment for convenient placement and hands free testing. Wet the durable sock and clip to evaporator filters for indoor wet bulb – great for finding target evaporator exit temperature. Clip to return vents for indoor wet bulb temperature – great for target superheat calculations. The ATWB1 can be used with any of our meters that measure temperature and any thermometer accepting aType-K thermocouple. HVAC/R technicians find the ATWB1 extremely helpful when data logging or anytime an extra hand is needed.The wrap-tab allows the thermocouple wire to conveniently store on the plug. Just wrap the excess wire around the wrap-tab. No more tangled messes in your tool bag.
