8 outputs (9 from version 3.03) which can be flexibly configure to operate 1 to 8-part variable ratio nutrient dosing, pH raise, pH lower, Irrigation, add water and alarm

Output voltage same as supplied voltage 12V to 24V AC or DC. Normally 24V DC supplied Nutrient measurement units EC, CF or ppm (EC x 500)

Measured range 0.00 to 9.99EC, 0.1 to 99.9CF, 0 to 4999 ppm Nutrient resolution 0.01 mS/cm, 0.1 CF, 5ppm

Nutrient measurement accuracy +/- 0.1 EC, 1.0 CF or 50ppm - temperature compensated Nutrient dosing range 0.10EC to 5.99EC, 0.1 to 59.9CF, 50ppm to 2999 ppm

pH resolution and accuracy – 0.1 pH pH measurement range 2pH to 12pH pH dosing range 4.5pH to 8pH

Temperature resolution and accuracy 1°C, 2°F

Temperaturemeasuring range 0-50°C, 32-125 °F   

Operatingtemperature range 0-45°C, 32-110°F (and not in directsunlight) 

 

Power source – mains transformer pack supplied; specify mains voltage and pin type (power to controller can be between 12V and 24V either AC or DC to suit the output devices) Outputs will have the same voltage as the supplied voltage from the power pack.

Large graphics display using simple four key interface

 Nutrient sensor uses DiPulseTM technique to resist fouling

Dosing fail safe shut-off (can be disabled)

if nutrient is below 0.1EC, 1CF, 50ppm 

if pH below 4.5pH or above 8.0pH 

if sensor fault detected (some pH faults cannot be detected) USB connection and software supports multiple controllers Sample pot supplied. 

Valves available separately with cables and flow restricting pipes Valves chemically resistant to 5% Phosphoric acid, 2% Nitric acid 

Compatible triple peristaltic pumps available separately as an alternative to solenoid valves.
