EH4W - Wireless Electronic Handle with ET2W Wireless Transmitter

The EH4W Wireless Handle connects to any Fieldpiece accessory head to easily make your accessory heads into standalone wireless instruments.  The EH4W handle can both measure whatever accessory head is attached directly to it, as well as receive a second measurement wirelessly from whatever accessory head is attached to the included wireless transmitter, model ET2W.  In addition the EH4W can also send wireless measurements, so you can use it with any Fieldpiece wireless meter, manifold, or system analyzer.  Wireless signals can be sent from up to 75’ away, so you can take your wet bulb measurements and have the live data in your hand while working on the condenser.
