Product Description
PAR Light Quantum Sensor to use with your WatchDog Data Logger. The sensor approximates the radiation between 400 and 700 nanometers, the most influential wavelengths for optimum plant growth.
The PAR Light Sensor includes a 6 foot data cable; which is plugged into an available external port on a Model 200, 225, 400, 425, or 450 WatchDog data logger. Once the sensor is in a representative "micro-climate", insert the data cable plug into the WatchDog external channel to log PAR Light data.
To connect an external sensor to the logger, plug the sensor cable into the logger port that has been programmed for that particular sensor. If the sensor is not connected, the message “sensor error” will appear on the LCD display for the respective logger port until the sensor is connected.
Sensor captures radiation between 400 and 700 nanometers. Range: 0-2500 umol m2s1. Sensor drift is 1% per year and includes a built-in level. Accuracy is +/- 5%. Maximum of two per logger.
