FLIR PV78 Solar Irradiance Meter with Tilt Angle, Compass, and Temperature Measurement

The FLIR PV78 is a solar irradiance meter that measures solar radiation, ambient and panel temperature, tilt angle, and compass direction for photovoltaic system installation and maintenance. It features a monocrystalline silicon sensor with an irradiance range of 0 to 1999 W/m² and accuracy of ±3% + 2 digits. The meter includes data logging for up to 9999 records and Bluetooth/USB connectivity for data transfer.

Advantages

The PV78 combines multiple measurement functions in one device, reducing the need for separate tools. Its backlit LCD display ensures readability in bright sunlight, and the adjustable auto power-off function helps conserve battery life. The included external temperature probe allows accurate panel temperature measurements.
