RS PRO Solar Power Meter ISM400, Solar Power

Looking for a versatile and reliable solar power meter? This RS PRO ISM400 solar power meter allows you to quickly and accurately measure solar power and is especially useful when you need to identify the optimal positioning and alignment of your solar panels.
The device has a four-digit liquid crystal display (LCD) and can calculate total solar energy against elapsed time or average solar energy per hour, so you don't have to use two different devices. It will also measure the percentage of solar power transmission through glass or heat insulation materials. The meter features data hold and data memory functions so you can save and keep track of your measurements. It's also versatile, allowing you to take readings in both W/m² (Watts per square meter) and BTU (British Thermal Unit).
The device comes with a user manual, tripod mounting screw and four AAA alkaline batteries, so it's ready to use. Solar meters like this one are commonly used in optical and solar power research facilities, meteorology and agriculture.
