ECRN-100 High-Resolution Rain Gauge

The ECRN-100 is best used in research studies or for measuring precipitation. Plug-and-log capabilities with the Em50 series data loggers.

PAR Sensor

Photosynthetically Active Radiation (PAR) is a measure of the light energy used by plants to drive photosynthesis. These measurements are used to estimate photosynthesis, biomass accumulation, and crop growth. This simple, no-frills PAR sensor is weather tight and ready for long-term field deployment, and has plug-and-log simplicity when used with the Em50 line of data loggers.

PYR Solar Radiation Sensor

Total solar (i.e., shortwave) radiation data have a wide range of uses, including distinguishing between latent heat flux and sensible heat, calculating an energy balance, and calculating evapotranspiration using the Penman-Monteith equation. This simple, accurate pyranometer allows you to measure total solar radiation over your chosen time interval. Plug-and-log simplicity when used with the Em50 line of data loggers.
