OTT HydroMet Solar Energy products

The SUV5 is a general-purpose instrument for applications in meteorology, for material testing, for monitoring of lamps and for use in ageing tests in solar simulators. The high quality dome and diffuser give optimised directional response. An optical filter provides sensitivity to combined UVA and UVB irradiance.

NR Lite2 is designed for routine measurement of net radiation which is the balance between incoming and outgoing radiation under outdoor conditions. The design of the NR Lite2 is unique. The double-sided detector has black conical absorbers with an anti-stick weather resistant protective coating. The NR Lite2 has a virtually maintenance free design. The output voltage is proportional to the net radiation. It can be directly connected to voltmeter or data logger with an mV input.

The CNR4 net radiometer measures the energy balance between incoming short-wave and long-wave Far Infrared (FIR) radiation versus surface-rejected short-wave and outgoing long-wave radiation. The CNR4 net radiometer consists of a pyranometer pair, one facing upward, the other facing downward, and a pyrgeometer pair in a similar configuration. The upper long-wave detector of CNR4 has a meniscus dome. This ensures that water droplets role off easily and improves the field of view to nearly 180°, compared with a 150° for a flat window.
