HI-9913 is a 2-in-1 pH and conductivity controller engineered for dosage of fertilizer solutions in hydroponics and agriculture.

HI-9913 measures pH from 0 to 14 and EC from 0 to 10mS/cm. Two separate set points can be user adjusted from 4 to 7 pH and 0 to 6mS/cm. The relays are activated when pH exceeds the set point or conductivity falls below the desired value.

Descriptions

Two pumps or electro-valves can be wired directly to the controller and be powered through the terminal. The operator can adjust two independent proportional settings for pH and conductivity. The time cycle is adjustable from 0 to 90 seconds, while the proportional band is 0 to 2 for both pH and EC. A matching pin/ground probe can be connected to the appropriate terminals to eliminate interference and prolong the pH electrodes life.

HI-9913 provides for an alarm relay which is activated in several circumstances. These include when the pH is below the set point by the operator-adjustable threshold of pH 0.5 to 2.5, or EC exceeds the set point by a value in the 0.5 to 2.5mS/cm range. The alarm goes off if the pH and/or conductivity are not corrected within the operator-determined time frame of 1 to 10 minutes. The alarm can be turned off during maintenance.

Fertilisation status can be ascertained from a distance through dosage and alarm LEDs.
