WatchDog Model 1650 Data Logger

Data Loggers are the cost-effective choice for recording environmental conditions over a period of time. Whether your needs are plant disease alerts or soil moisture monitoring, the WatchDog Data Logger will deliver the information you need for timely, accurate data that will result in increased profits. The LCD display confirms logger operation and provides current sensor readings. View the current temperature during a freeze event, or soil moisture prior to irrigating – without downloading to a PC. Customizable with up to four unique external plug-in sensors. Change monitoring parameters from one season to the next, simply by connecting a different sensor - keeping investment costs down while making more profitable decisions. See our WatchDog Data Logger Sensors page. The Radiation Shield is also recommended.
