The company says the Solar Survey 100 and 200R instruments are ideal for both PV and solar thermal testing and contain new functions – a digital compass, digital tilt meter and a dual channel precision thermometer.
The 200R also encompasses a large internal memory and USB interface for downloading results to a PC. The 200R has wireless capability to connect with the Seaward Solar PV150 electrical installation tester. This enables real-time irradiance to be displayed and measured at the same time as testing is being undertaken.
