The ISO-TECH ISM series (ISM400 and ISM410) solar power meters are designed to measure radiated and transmitted solar power at an installation, in order to determine the optimum positioning and alignment of solar panels and the total solar energy against elapsed time or average solar energy per hour calculation. The product range meets the requirements of safety, health and industrial safety officers and determines the percentage of solar power transmission through glass, heat insulation materials, sunshades etc.
The meters have the ability to operate at a temperature range of 0°C to +50°C and have a battery life of 100 hours. They are frequently used in solar power research, solar radiation measurement and solar transmission measurement applications, as well as physics and optical laboratories.
The series features a wide spectral response of 400–1000 nm, full cosine correction for the angular incidence of the solar illumination, ±0,1 W/m² resolution, a range of 2000 W/m², a basic accuracy of ±10 W/m² or ±5% (whichever is greater) and data HOLD/MAX/MIN/AVG modes. Both products within the series include a 4-digit LCD display, a sampling rate of four times per second and a 99 set memory capacity.
The ISM series is supplied with an instruction manual, four x AAA alkaline batteries and a tripod mounting screw. The ISM410 is also supplied with an RS232 interface cable and software for PC interface.
