PRODUCT DESCRIPTION
The TH-GH2 is a rod-probe quantum meter for measuring photosynthetically active radiation (PAR) inside plant canopies. The rod probe averages light across its length, giving a representative reading where point sensors would mislead, and the logger records at one-second intervals with storage for 32,768 records.
Results are available in W/m² or µmol/m²/s, download by USB with optional RS232, and run from a built-in lithium battery or 12V adapter.
