Whats new

The EvapoIrrigator MK1.1 is an exciting addition to the E&TS Ltd range of irrigation control equipment. It offers growers automatic adjustment of irrigation frequency according to weather conditions. Fitting an EvapoIrrigator to a simple irrigation timer transforms it into an intelligent controller that will reduce water wastage, improve crop quality and ultimately boost the bottom line. It is compatible with any existing timer/controller that can accept a remote start signal. The key feature of the EvapoIrrigator is its ability to integrate the signal from the ES4 pt100 Evaposensor. It triggers irrigation when accumulated evaporation reaches a user adjustable target value.

Installation is straightforward and flexible.

When used as a ‘stand alone’ integrator, the controller will provide a start for an irrigation controller, with degree hour integration adjustable from 1°h to 999°h. When the number of degree hours accumulated reaches the set adjustable targer, a potential free start relay contact closes for 5 seconds.

The output current loop, 0 - 20mA, when connected to the unique integrating feature of the ETS range of irrigation controllers, automatically adjusts the set watering times to suit the growing environment

The output current loop 0 - 20mA can be used as a °hour programmed start(s) for other controllers 

Field tested on six commercial nurseries in HDC funded research (HNS 159, HNS 159A; reports available to levy-payers from the HDC), evaposensor control offers many advantages.

ALL CONTROL UNITS ARE SUPPLIED WITH COMPLETE TECHNICAL AND INSTALLATION INSTRUCTIONS.
