COARSE FREE DRAINING SANDY SOILS

Application:

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 in all field crops, vines and trees planted in coarse, free draining sandy soils where tensions above 30 cb are rarely expected and finer resolution near saturation is needed. Instrument is also suited for conditions where rapidly changing moisture tensions need to be observed.

Specification:

  • 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. (SPECIAL FEATURE)
  • 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.
  • All solvent welded joints are permanently leak proof.
  • Strong ceramic tip designed for “quick flo” fast reponse and a high flow rate 300% of conventional tips. (SPECIAL FEATURE)
  • Threaded connection (uses ‘O’ ring seal) for ceramic tip to instrument, allows easy storage of tip when not in use.
  • Ceramic tip colour blue.

AUTOMATIC SOIL MOISTURE DATA RECORDER

Application:

The Watermark Monitor is a Data-Logger which automatically takes soil moisture readings. This reading history provides you with a vivid picture of the soil moisture profile your irrigation practices have created. This data can be evaluated to determine ways to improve the irrigation scheduling for optimum results. Individual Watermark sensor readings display on the Monitor and can be taken at any time manually. The In–Field display allows you to make on the spot checks, necessary for scheduling purposes while the Monitor is taking periodic readings to record the performance history. Irrometer® switching pressure gauges (optional) can be 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.

Specification:

  • Automatically Reads Sensors.
  • 8 Sensor Capacity.
  • Reading Frequency from every minute to every day.
  • Watergraph Software included.
  • In–Field display of current reading.
  • Download history to a computer.
  • 9 Volt battery included.
  • Complete with 8 sensors (1 temperature and 7 watermarks 0 – 200 centibar reading.)
  • The Watermark Monitor is user programmed for the individual characteristics of the site to be monitored:
  • A unique location
  • The time interval to automatically take readings, from once every minute to once every day
  • A unique name for each sensor being read.
  • The date and time you want readings to begin.
  • The selection of sensor type for each input port:
    – Watermark Soil Moisture Sensor.
    – Temperature Sensor in fahrenheit.
    – Temperature Sensor in Centigrade.
    – Switch Position.
    – Off
  • Monitor easily mounts in the field. Sensors are placed in the root zone at depths where monitoring is desired. Sensor wiring can be extended 1000 metres using 2.5mm2 cable
  • Stored readings are downloaded to a computer for display, as in Fig.1. Other display options are available.
  • The WaterGraph 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 spreadsheet or graphing programs, like Microsoft Excel®.

Automation for Irrigation Controllers

Application:

Watermark soil moisture automation works with the irrigation controller to allow water to be applied only when necessary. This advanced method of irrigation control provides good water conservation, while maintaining the health of the landscape. Applying just the right amount of water, no more than necessary and no less than required, to your turf and landscape.

Specification: WS-200 Sensors

  • Two concentric electrodes buried in granular matrix material, held in place by a stainless steel case. Matrix material provides buffering for the effect of salinity levels in soil.
  • Unaffected by freezing temperatures, does not require removal during winter periods.
  • Electrical resistance type sensor, 500 – 30 000 ohms resistance.

Operation

Studies have proven that WATERMARK moisture control matches plant/turf need for water and regulates irrigation to this need. The Adjustability of the “switch” allows for finetuning the control to specific climates, plant materials and soils. Just like a thermostat tells the furnace or air conditioner to go on, the WATERMARK ELECTRO NIC MODULE tells the irrigation time clock if water is needed. If the soil is drier than the adjustable setting, irrigation will take place. If the soil is wetter than the setting, that irrigation cycle will not occur. The WATERMARK ELECTRONIC MODULE eliminates the need to reprogram the time clock for seasonal changes or during rainy periods, hot spells or vactions.

Hunter Mini-Clik
Hunter Mini-Clik Image

Description:hunter-mini-clik-2

There’s nothing more embarrassing – or more wasteful or costly – than an irrigation system that runs when it doesn’t have to…in the rain. Mini-Clik provides the simplest, most effective to prevent sprinklers from coming on during or after rain. It easily installs on any automatic irrigation system, then shuts sprinklers off in a storm and keeps them off, automatically compensating for the amount of rainfall that occurred. Disks absorb water and expand proportionally to the amount of rain that fell. As the moisture-laden disks expand, they eventually activate a switch that interrupts the circuit from the controller to the solenoid valves. Once dry, they contract and release the switch. thus, Mini-Clik automatically resets without ever affecting the controller. There’s no better way to ensure that a system isn’t watering when it isn’t necessary.

Features:

  • Easily installs on any automatic irrigation system
    Versatile enough to work with all popular controllers
  • Patented mechanism cannot be fouled by dirt or debris
    Reliable operation, no false shutdowns
  • Adjusts to actuate at various rainfall quantities
    Set from 3 to 25mm
  • Includes 7.6m of 1.0mm² two conductor wire
    Fast and easy mounting out of site
  • 5-year warranty
    Your guarantee of dependable operation

Specifications:

  • Switch rating: 10.1 amps at 125/250 VAC
  • Wiring: MC2: Typically interupts the common ground wire between the solenoid valves and the controller.
  • Included: 7.6m of 1.0mm² two conductor wire, two mounting screws, controller identification label and detailed instructions
  • UL listed

Bypass switch box: give any automatic controller’s remote hunter-mini-clik-bpsensors the capability to bypass. It’s the easy way to put a system in the manual mode as would be needed during servicing and troubleshooting operations. Features a compact, heavy-duty switch mechanism, the Bypass Switch Box mounts quickly and easily with it’s no-strip wire connectors and supplied adhesive tape
