PRODUCT DESCRIPTION
The TH-GH1 is a portable data logger for photosynthetically active radiation (PAR), the 400–700 nm band that drives plant growth. It records at one-second intervals and stores up to 32,768 records, reporting in either W/m² or µmol/m²/s.
Dual power — a built-in 3.6V lithium battery or 12V adapter — supports both field trips and fixed installations, with USB data download and optional RS232.
