Both a solar irradiance meter and multimeter in one comprehensive unit, the DiLog SL102 is a versatile tool suitable for use by anyone who works with solar PV equipment (particularly when installing panels).

Shaped like a standard multimeter and with a built-in sensor attached to a flexible cable, the SL102 is easy to use and allows testing to be carried out safely and accurately (plus the flexible cable is ideal for reaching difficult installations).

The meter is capable of measuring solar irradiance to 1999W/m² or 634BTU/ft2*h. A dual display integrated into the front of the unit shows both the irradiance value and a a voltage measurement simultaneously to speed up the time you spend testing.

In addition this meter also comes with MIN/MAX mode, auto data hold, AC/DC voltage measurements to 600V and much more!
