Fieldpiece EH4W Wireless Handle for Accessory Heads

The Fieldpiece EH4W is a wireless electronic handle that lets you take two simultaneous measurements from different locations without an assistant. One accessory head plugs directly into the handle; a second head fitted with an ET2W wireless transmitter sends its readings to the EH4W wirelessly at up to 75 feet — ideal for supply and return temperature checks, or any measurement requiring two points at once.

For the wireless transmitter that pairs with the EH4W, see the Fieldpiece ET2W. See all electrical testing tools at HVAC Shop AU.
