The Multiple Hydrozone System (MHS) allows independent moisture control of valve groups when all valves share a common ground. The MHS interfaces with any 24 VAC irrigation controller for soil moisture automation.
Easy to Install – new or retrofit
Individual area moisture control – reads, reports, adjusts
The Irrometer, first introduced in 1952, has continuously been the leader with every exclusive feature symbolic to Irrometer allowing the instrument to measure soil moisture tension and automatically control watering in all turf crops planted in course free draining sandy soils.
Hermetically sealed gauge, with moulded in diaphragm which keeps out dirt and moisture, also compensates for variations in temperature and barometric pressure.
Air free gauge, water seal prevents air entering gauge, gauge and chamber remain full regardless of water level in instrument
Gauge readings 0 through 40 centibar readings in 1 centibar increments.
Body constructed of tough durable plastic impervious to attack by chemicals or electrolysis.
Large cap for easy operation and better control assists with quick servicing.
The Irrometer Watermark soil moisture sensor designed to measure soil moisture tension in irrigated field crops, vines, and trees planted in all soil types suitable for agriculture and turf irrigation systems. Suitable for use with data logging devices.
Unaffected by freezing temperatures, does not require removal during winter periods.
Can be used for automatic control in irrigation systems. (requires interface unit WEM)
0 – 200 centibars of soil water suction, non linear, measures full soil water range.
Sensor manufactured from non corrosive parts, 50mm x 21mm in dimension
