The Middleton Solar PG01 Pyrgeometer measures the long wave radiation emitted by the atmosphere (downwelling) or by the Earth surface (upwelling). It uses a passive thermoelectric sensor shielded by a flat silicon window. The PG01-E version has an in-built amplifier with a millivolt output for easy signal measurement.
The EV2-H Ventilator/heater Unit is available to combat dew formation.
