Solarmeter Model 10.0 Global Solar Power Meter - Measures 400-1100nm with range from 0-1999 W/m²

The Model 10.0 Global Solar Power Meter uses a silicon photodiode. Applications include monitoring solar pv panel input, measuring outdoor solar irradiance, and estimating PV array power output. To operate, press and hold push-button switch on face of unit. Aim sensor window cap in top panel of meter directly at sun or perpendicular to panel array. Note reading on LCD and record value. Battery operation voltage is 9V down to 6.5V. Below 6.5V the LCD numbers will begin to dim, indicating the need for battery replacement. Under typical service load, the battery should last approximately 2 years.
