Fieldpiece - The ATWB1 K-type 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 a K-type 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.
Accuracy: +/- 4ºF (2°C) ; ±1°F (0.5°C) after field calibration, 32 to 176ºF (0 to 80°C)
Probe insulation: Calibration and atmosphere will affect maximum useful temperature in applications. The wire insulation is designed to withstand a maximum continuous use at 400°F (204°C ) but the sock may become damaged at temperatures above 150°F.
Plug: K-type thermocouple male mini plug.
