The Fieldpiece ATWB1 Type-K Wet Bulb Alligator Clip Thermocouple can clip to HVACR equipment for convenient placement and hands-free testing. For accurate indoor wet bulb measurement and for finding target evaporator exit temperature, the unit can be clipped to evaporator fins and the durable sock can be moistened. For accurate indoor wet bulb measurement and for finding target superheat calculations, the unit can be clipped to return vents.

The ATWB1 can be used with any of the Fieldpiece meters that measure temperature or any thermometer accepting a Type-K thermocouple. The ATWB1 is ideal for HVACR technicians when data logging or any time that an extra hand is needed. The wrap-tab allows the thermocouple wire to conveniently be stored on the plug by wrapping the excess wire around the wrap-tab. This convenient storage option avoids tangled messes in the user's tool bag.
