PRODUCT DESCRIPTION
The TH-SL is a digital solar radiation ammeter for instantaneous measurement of solar radiation up to 2500 W/m². It displays the current irradiance directly, so field technicians can check conditions on the spot without logging or post-processing.
A built-in 3.6V lithium battery or 12V adapter powers the unit, which operates from −20 to 70°C for year-round field use.
