The new mini nutrient controller can work in units of EC, CF or TDS and comes complete with a powerpack andsensor. The controller continuously measures the nutrient concentration in the mixing tanks and adds A and B nutrients as required to maintain the EC set point.
The controller counts the number of doses and in the event of the dose count per hour exceeding a set value, an alarm can be sounded. In addition, alarms can be sounded should the EC wander outside user set limits. If the dose count per hour exceeds a user setting, the controller will stop dosing.
This product is aimed at the budget conscious and for those who don't need a computer interface. Ideal for hobby gardeners, schools, etc. Even large commercial growers use them - particularly for water pre-treatment (pH) or if they have a trial area with a number of reservoir tanks.
Warranty is for two years providing that the controller is installed in a clean, dry position out of direct sunlight, and is not damaged either mechanically or chemically.
The EC Mini-doser is cheap enough to use as a mains powered monitor, continuously displaying the measured electrical conductivity. By adding solenoid valves or dosing pumps it becomes a low cost dosing system.
- Reading can be changed to EC or CF
- Timed dosing for easy set-up
- Range from 0 to 99CF (0 to 9.9mS)
- Resolution 0.1CF (0.01mS) below 10CF, then 0.5CF (0.05mS) from 10 CF to 40 CF and finally 1CF(0.1mS) above 40CF.
(this provides accuracy at the lower end where it is required)
- Two year warranty
- Graphite electrodes for minimal contamination
- Easy to recalibrate by using 27.64CF standard solution
- Built-in alarm (can be turned off)
(solenoids/ feeding kit is addtional)
