Buy with confidence! Daystar's meters are being used by satisfied customers throughout the USA and over 60 countries around the world.
The Daystar solar meter provides an accurate reading (3%) from 0 - 1200 Watts/m2 when they are pointed at the sun. Resolution is 1 W/m2, maximum display reading is 1999. The irradiance value is presented on a 0.75" easy-to-read LCD display. The meter is (2.5" x 4.5" x 1.0" inches) (6.4 x 11.4 x 2.5 cm) and weighs (less than 5 ounces) (140 g) with the 9-V battery installed.
PV Sensor: The meter uses a polycrystalline silicon PV cell as the sensor. The cell is mounted on the top end of the meter, perpendicular to the display. The sensor responds to a spectum bandwidth of approximately 0.3-1.1 microns. A generic spectrum for a silicon PV cell is here The meter is intended for outdoor measurements of natural sunlight. The PV sensor is located behind a plastic diffuser.
