Irrometer
Company, Inc. Notification
of recent events relating to Irrometer products, and other soil
moisture references of interest: Cellular
telemetry is now available as an option for remote data collection from
the Watermark Monitor. Upgrades to our Monitor firmware and the operating software, WaterGraph, are available upon request. Several upgrades have been made to enhance the graphing capabilities, such as easier sensor averaging, threshold reference lines for recommended irrigation management range and individual data point reference display. Two new products have been introduced to address needs of the landscape irrigation marketplace. A battery powered version of the Watermark Electronic Module is now available for use with battery powered controllers. The new WaterSwitch is a simplified control device for use with residential style irrigation controllers.

Penning President Research Bulletin #5 Oct 2005 Notification of recent events relating to Irrometer products, and other soil moisture references of interest:
We are now introducing a Radio Telemetry option available for our Watermark Monitor. This option allows wireless downloading of collected readings from field locations using a spread spectrum radio with no FCC licensing requirement.
We are also now providing adapters to connect our Irrometer Model RSU (4-20mA transducer version) to be connected to the Watermark Monitor for automatic data-logging of tensiometer readings.
Upgrades to our Monitor firmware and the operating software, WaterGraph, are available and will be downloadable from our website soon.

Irrometer offers a Watermark Remote Reader (WRR), which makes taking manual readings of groups of sensors quicker and easier. Up to six (6) Watermark sensors can be wired to the WRR. The handheld meter is clipped onto the WRR and a selector switch lets you quickly scroll through and take the readings with the meter, rather than having to clip the meter onto each pair of sensor wires individually.
