0.9 kg (2 lb) with 10 m (33 ft) cable

Impedance*

20 to 200 Ω

10 to 100 Ω

* Impedance is defined as the total electrical impedance at the radiometer output connector fitted to the housing.

It arises from the electrical resistance in the thermal junctions, wires, and passive electronics within the

radiometer.
