Fieldpiece accessory heads can be used with a variety of handle options to operate as either stand alone meters, data loggers, or as wireless instruments. The modular design of these tools makes them a cost effective solution for a variety of HVAC related measurement needs. Because each measurment solution is independent, you can select the measurements that you need without paying for features you may not use. Coupled with the Fieldpiece HG3, calculations of Total superheat, temperature split, or an air balancing process can be quickly carried out without the need for additional calculations. Because these tests are carried out in real time via wireless probes, productivity can be significantly increased.
