Fieldpiece JL3KH6 Job Link System Charge and Air Kit provides a full system snapshot quickly and easily. This kit consists of two pressure probes, two pipe clamps, and two psychrometers in a quick access padded case. All measurements can be sent up to 350 feet away directly to your mobile device with the Job Link app. Each tool is designed for agility and speed. The pressure probes fit into tight spaces. The pipe clamps use the Rapid Rail sensor design, which delivers accuracy, speed, and agility, even on the most awkward pipe configurations. The psychrometers' flexible narrow probes and configurable magnet make it easy to measure supply plenums, ducts, and elevated registers.
