PRODUCT DESCRIPTION
The TH-TF1 is a portable solar radiation data logger for field observation of total solar radiation. It records at intervals down to one second with button start, cycle operation and threshold alarms, storing up to 32,768 records across a 0–2500 W/m² range.
A built-in 3.6V lithium battery (or 12V adapter) powers long unattended runs, and data transfers to a PC by USB cable with optional RS232. At only 178 g, the logger and its pyranometer sensor travel easily between field sites.
