The WM261 transmitter can measure, convert, and simulate temperature and humidity signals for transmission. These two parameters are transmitted to the remote receiver through analog signals. This transmitter comes with a built-in sensing/conversion module highlight Specially designed for high-precision measurement in controllable environments Output signal selectable Linearization of isotherms is optional
