Irrometer Watermark 900M Monitor

Field Data Logging

The WATERMARK monitor is a standalone data logger, providing users with a reliable, simple, and effective means of collecting information in the field. In addition to recording data, the monitor's screen can be used to view readings at any time to verify conditions.

The monitor logs soil moisture, soil temperature, irrigation on/off status, and rain gauge counts to provide an accurate record of your irrigation program's performance. Watermark 200SS sensors or IRROMETER tensiometers equipped with RSU-V can be used to collect soil moisture data.

The information can be downloaded directly to a computer via the built-in USB port using the included WaterGraph software, which also features graphical functions for visualization. The downloaded data is stored in a CSV file that can also be accessed using spreadsheet or text editing programs.
