This HVAC/R-focused kit bundles REED's Bluetooth Smart Series vane anemometer, thermo-hygrometer, and thermocouple thermometer with a pair of Type K spring-loaded pipe clamp probes, all in one carrying case. The instruments sync over Bluetooth 5.0 to the REED Smart Series app for simultaneous data logging of airflow, temperature, and humidity, while the pipe clamps let a technician read supply/return line temperatures directly off refrigerant or water pipes up to about 1.4 in diameter. It suits HVAC and refrigeration technicians who need airflow, psychrometric, and pipe-temperature checks on the same service call.
