This RS PRO ISM410 solar power meter is a compact and versatile device you can use to quickly and accurately measure solar power. The meter is particularly useful when you need to ascertain the optimal alignment and position of solar panels.
This device allows you to calculate total solar energy against elapsed time or average solar energy per hour. It will also determine the percentage of solar power transmission through glass or heat insulation materials. You can take readings in two units, W/m² (Watts per square meter) and BTU (British Thermal Unit), so there's no need to convert them. It also gives you options to hold and save the data.
You can also connect this meter to your PC with the RS232 cable included in the kit and use the software supplied on the CD ROM. The kit also includes a user manual and AAA alkaline batteries, so you can start working with your solar meter right away.
