Dwyer Model SLR-01 Handheld Solar Power Meter

Measures up to 1999 W/m2, Auto-Ranging


Model SLR-01 Handheld Solar Power Meter measures the solar energy to determine the appropriate position or location for solar panels. It can be used to test the performance of solar receivers and solar window treatments. Using the end-mount light sensor, the meter is able to read and display in units of W/m2 and BTU/(ft2*h). The large numbers and high contrast of the LCD make it easy to read the measurement, even in bright areas. Applications include solar farms, office buildings that utilize energy harvesting sensors, and telemetry systems.
