SR22

Secondary Standard Pyranometer with Quartz Domes - Extended Spectral Range

SR22 is a solar radiation sensor of the highest category in the ISO 9060 classification system: secondary standard. On top of the features and benefits of the successful SR20 pyranometer, SR22 has domes made of high-quality quartz, resulting in an extended spectral range. Covering the full solar spectrum, SR22’s extended spectral range potentially offers lower measurement- and calibration uncertainties compared to pyranometers with glass domes. SR22 is typically used in high-accuracy climatological networks.

SR22’s spectral range of 190 to 4000 x 10-9 m. SR22 covers the full solar spectrum
SR22’s low temperature dependence makes it an ideal candidate for use under very cold and very hot conditions
SR22 pyranometer uses a state of the art thermopile sensor with black coated surface

SRA01

Second class albedometer

SRA01 albedometer is an instrument that measures global and reflected solar radiation and the solar albedo, or solar reflectance. It is composed of two identical second class pyranometers with thermopile sensors, the upfacing one measuring global solar radiation, the downfacing one measuring reflected solar radiation. SRA01 complies with the latest ISO and WMO standards.

NR01

4-component net radiometer

NR01 is a market leading 4-component net radiometer, mostly used in scientific-grade energy balance and surface flux studies. It offers 4 separate measurements of global and reflected solar and downwelling and upwelling longwave radiation, using 2 sensors facing up and 2 facing down. NR01 owes its popularity to its excellent price / performance ratio and major improvements relative to comparable instruments. Advantages include its modular design with 2 pairs of identical sensors, low weight, ease of leveling, and low solar offsets in the longwave measurement. The unique capability to heat the pyrgeometers reduces measurement errors caused by dew deposition.

Lowest price level at top level performance
Heated pyrgeometers, best night-time data availability
High-accuracy shortwave calibration
Low weight, low mounting costs
Modular design, 2 pairs of identical sensors
Practical leveling, servicing and recalibration

HF02

Flare radiation monitor / heat flux sensor

HF02 is a sensor that measures radiant heat flux or thermal radiation in the outdoor environment. A common application is monitoring the radiation emitted by flares. HF02 is certified for use in potentially explosive atmospheres, and is rated for radiation levels up to 15 x 10³ W/m². We recommend use of HF02 in a decision-supporting role only, and not to use measurements of HF02 as the main or sole source of information for judging safety.

Robust
All-weather
Suitable for potentially explosive environments

HFP03

Ultra sensitive heat flux plate

HFP03 is an ultra sensitive sensor for measurement of small heat fluxes in the soil as well as through walls and building envelopes. The total thermal resistance is kept small by using a ceramics-plastic composite body. See also model HFP01: putting several HFP01 sensors electrically in series is an alternative for using HFP03.
