Solar power meter 4000 W/m²
The TM-750 measures solar radiation up to 4000 W/m² or 1268 BTU/(ft²·h) with a 3½-digit LCD that reads to 3999. It is intended for electricians, researchers and installers who need quick irradiance checks on site or in the lab.
Range 4000 W/m² and 0.1 resolution
Resolution is 0.1 W/m² and 0.1 BTU/(ft²·h). Accuracy is typically within ±10 W/m² or ±3 BTU/(ft²·h) or ±5 %, whichever is greater in sunlight, plus a temperature-induced error of ±0.38 W/m²/°C from 25 °C. Sampling runs at about four times per second.
Pocket build with data hold
The red housing weighs roughly 90 g and measures 108 × 48 × 23 mm. It runs on two 1.5 V AAA batteries, which are not included. Data hold, maximum and minimum capture let the user freeze or review readings without a connected device.

Questions about this item
How does the TM-750 perform when used with older solar panels that produce lower irradiance levels?
The meter measures from 0.1 W/m² up to 4000 W/m², so it captures the output of older panels without saturation.
How can I verify the TM-750 is reading correctly after turning it on?
Check that the 3½-digit LCD shows values within the ±5 % accuracy spec and use the Data Hold or MAX/MIN functions to confirm stable readings.
What comes in the box with the TM-750 and what must I purchase separately?
The unit includes the meter only; two 1.5 V AAA batteries are not included and must be bought separately.
