PYR20 pyranometer, or solar Radiation Sensor, measures global radiation of both direct and diffusion of solar irradiance. The internal temperature compensation minimizing the error caused by heating of the sensor. Each sensor is calibrated against Eppley Precision Spectral Pyranometer and offers excellent accuracy and consistency. The sensor is applicable for science research, solar power , greenhouse, weather station etc.<br> Measurement range to 2000W/m2, Spectral range 400-1100nm<br> Output interface with RS485, Voltage or Current<br> Temperature compensated<br> Level indicator and spring loaded for installation<br> Water proof to IP66 can be used outdoor<br> High accuracy and consistency with excellent stability<br> Reverse power protection and Built-in TVS/ESD protection<br> Pyr Range : Range:0-2000W/m2, Accuracy 5%, Resolution:1W/m2<br> Spectral Range : 400-1100nm<br> Direction Error : Percent of reading: 3% (0 - 70); 10% (70 - 85)<br> IP Ratings: IP66<br> Operating Temperature : -40~85<br> Installation : Screw hole * 3<br> Colour:black<br> Material:plastic<br> type:4-20mA<br> Package Contents:<br> 1 x Sensor<br> Only the above package content, other products are not included.<br> Note: Light reflection and different displays may cause the color of the item in the picture a little different from the real thing.
