The WATERMARK Monitor family of data loggers are devices that automatically take
soil moisture readings. This reading history provides a vivid picture of the
soil moisture profile your irrigation practices have created.
Data downloaded from a WATERMARK Monitor can be evaluated to determine ways to improve the irrigation scheduling for optimum results. Individual sensor readings display on the Monitor and can be taken at any time manually, allowing you to make on the spot checks as necessary for scheduling purposes while periodic readings are being taken to record the performance history. Record soil moisture, soil temperature, switch positions, and rain gauge counts for an accurate record of the performance of your irrigation schedule. IRROMETER switching pressure gauges are used as switch position sensors to indicate when the system pressure is on and off to display the irrigation events. Temperature compensation of the soil moisture reading is automatic by using one or more temperature sensors or programming a default value. The IRROMETER Model RSU (4-20mA transducer) can also be read (wiring adapters and auxiliary sensor power required). Spring-loaded terminal strips are provided for sensor connections, which allow for easy installation and never need tightening. Included wire entry strain relief connectors keep enclosure sealed and retain wires. Data can be downloaded directly to a computer via USB, Serial, with a PDA or via wireless telemetry.
The WATERMARK Monitor is the standard wired version of our data logger, providing users with a reliable, simple, and effective means of collecting information.
WATERMARK Monitor Features:
The WATERMARK Monitor is user programmed for the individual characteristics of the site to be monitored:
Stored readings are downloaded to a computer for display. Other display options are available. The software, included with the WATERMARK Monitor, is used to set up your individual site profile, launch the data-logger, download recorded history and graphically display the results. The data file created can also be opened by some spreadsheet or graphing programs, like Microsoft Excel®.

The WaterGraph Data Shuttle (900-DS) is a device that downloads collected data
from either 900M or the No Longer Available 950R Series WATERMARK Monitors and stores the data
on a multimedia card (MMC). The card can be removed from
the Data Shuttle, inserted in to a reading device
connected to a PC, and read by WaterGraph software for analysis of the recorded data.

Data access options for both the 975 IRROmesh Wireless Monitors and 900M Wired Monitors improve productivity by bringing important soil moisture information to you. Remote areas and multiple crop locations can be monitored from a central location. The remote access components are modular in design and can easily be added to an existing Monitor installation. World-wide access to 900M or 975 data is simple with the use of a Cellular Gateway and the Internet.
