pH and Conductivity Controller (Wall Mounted) - HI9913-2
- Proportional pH and conductivity (EC) control.
- Triple contact alarm system.
- Cost effective 2-in-1 design for versatility.
Easy Installation
Designed with mounting holes molded into the housing to assure simple, quick and secure installation without the need for additional hardware. Once all electrical connections are made, the protective cover can be installed over the front panel making it possible to perform all adjustments without disassembling any part of the unit.
Triple Contact Alarm System
When activated, the alarm contacts will open or close, triggering the mechanism of your choice, whether a buzzer, light or any other electrical device. The alarm is activated when the measurements stray away from the set point by a predetermined value in the 0.5 to 2.5 pH range.
Visual Status Indicators
Fertilization status can be ascertained from a distance through dosage and alarm LED’s.
Isolated Recorder Output
The ability to record the data from the process you are monitoring greatly enhances process troubleshooting. By simply connecting a recorder to the controller's output terminals, you are able to acquire a hard copy of the readings for demonstrative or analytical purposes. The recorder output terminals are isolated from the controller to avoid any interference and are user-switchable between 0 to 20 mA or 4 to 20 mA.
Durable Construction
This controller is housed in a rugged, fiber-reinforced, self-extinguishing rugged, modular, fiber-reinforced polypropylene housing. Polypropylene has properties that will resist the harmful effects of most chemicals.
BNC Connection
The electrodes can be installed quickly and easily. Simply plug the universal BNC connector into the socket and twist it into a secured position.
