Product Description

The HI 9913 is a wall-mounted, dual Electric Conductivity (EC)/Total Dissolved Solids (TDS), and pH controller for dosage of fertilizer solutions in hydroponics. Two separate points can be user-adjusted from 4.0 to 7.0 pH and 1.0 to 4.0 mS/cm. The controller provides for pH and conductivity/TDS relays, and proportional control to save on the use of chemicals and fertilizers. It operates with the optional Hanna four-ring probes to provide a linear and repeatable measurement.

The EC/TDS probes incorporate a temperature sensor, and the pH circuitry provides for a ground probe to avoid electrical noise and interference. Both are sold separately and can be installed quickly and easily. The controller automatically compensates (ATC) for the temperature affect, and measurements are displayed on a large, LCD screen. It incorporates a triple contact alarm system, which trigger the mechanism of choice, and is housed in a modular, fiber-reinforced ABS housing.

Range is 0.00 to 14.00 pH; 0.00 to 10.00 mS/cm (EC) + or 0.02 pH; 2% F.S., with resolutions 0.01 pH; 0.01 mS/cm. The device operates on 220/240V or 110/115V at 50/60Hz. Dimensions are 181 x 221 x 142 mm/7.1 x 8.7 x 5.6 (H x W x D), and weighs 1.6 kg (3.5 lbs.).

Wall-mounted conductivity/TDS, and pH controllers meet a variety of process control requirements in horticultural, hydroponics, and agricultural applications, as well as boilers and cooling towers.

Hanna Instruments manufactures analytical instrumentation and supplies, including pH meters, electrodes, chemical reagents, and buffer solutions. The company, founded in 1978 and headquartered in Woonsocket, RI, meets International Organization for Standardization (ISO) 9001 standards.
