Each irrigation program has one pH and one EC setpoint. The start condition of the program. the irrigation sectors and the time or volume for each sector are user defined. The irrigation water is pH corrected based on the pH control. with acid or alkaline solution and can contain nutrients for crops based on up to 4 fertilizer receipts.  Correction of time or volume of irrigated water can be based on accumulated solar radiation or can be manually requested by user. Agitator control and filter cleaning control are performed automatically. The instrument reads up to 3 EC probes. one to verify the incoming water EC. and the other two are in-line redundant for safety to measure the current irrigation water EC. The two pH electrodes are mounted in-line redundant for safety to read the irrigation water pH. The instrument provides an alarm system and logging organized on user selectable three levels.\u003c\/p\u003e\n\u003cp\u003e\u003cbig\u003eIrrigation control\u003c\/big\u003e\u003c\/p\u003e\n\u003cp\u003eIrrigation control differs based on the type of control: by irrigation water volume or by irrigation time; the number of sectors that have to be irrigated. the available sources of water for irrigation – one or more with or without reusing the irrigation drain water.\u003c\/p\u003e\n\u003cp\u003eIrrigation control is started by opening the irrigation valves and starting the main irrigation pump.

The irrigation water is pH corrected based on the pH control. with acid or alkaline solution and can contain nutrients for crops based on up to 4 fertilizer receipts.  Correction of time or volume of irrigated water can be based on accumulated solar radiation or can be manually requested by user. Agitator control and filter cleaning control are performed automatically. The instrument reads up to 3 EC probes. one to verify the incoming water EC. and the other two are in-line redundant for safety to measure the current irrigation water EC.
