Net Radiometer

The Net Radiometer measures what air and PAR sensors cannot: how much energy your crop is actually gaining or losing to its surroundings. One continuously updated number in W/m2, covering the full radiation balance (solar plus longwave), positive when the crop absorbs energy and negative when it loses energy. Growers use it to time screens on a real trigger, to check whether minimum pipe is doing its job, and to spot night-time radiative cooling before condensation and Botrytis set in. Wireless and solar-powered, with an operating range from -40 to 80 degrees C.
