The NR Lite2 is a single component net radiometer used for monitoring the difference in incoming radiation from the Sun and sky and outgoing radiation from the ground. The NR Lite2 uses a double-sided thermopile detector fitted with black PTFE coated conical absorbers with a single output for the net radiation. The sensor covers a very wide spectral response from the Ultraviolet (UV) to far infrared (FIR). The NR Lite2 has an integral mounting rod for fitting to masts and poles with a 15m signal cable and stick to prevent birds settling on the sensor. The single output and wide spectral range makes this units ideal for monitoring the total net radiation in a wide range of different applications.

The CNR4 net radiometer integrated 4 solar sensors into a single instrument body. The CNR4 consists of a pair of pyranometers and a pair of pyrgeometers. Each pair has one facing upwards for incoming radiation and one facing downwards for the outgoing radiation. The CNR4 has four separate output signals from the sensors, plus integrated temperature outputs. The signal outputs represent the incoming and outgoing short-wave (Solar) and long-wave (atmospheric and terrestrial) radiation, whilst the temperature reading can be used to compensate the pyrgeometer output. Units are supplied with a screw-in mounting rod for fitting to a mast and poles, bubble level and two 8-pin connector ports. An optional heated ventilation unit, the CNF4, is available to minimise offsets, maximise...
