Extremely accurate and simple to install, Hanna’s mid-range controllers offer economical, constant monitoring of pH, Oxidation Reduction Potential (ORP), Electrical Conductivity (EC), and Dissolved Oxygen. The compact, easy-to-use controllers are designed to consistently perform in most environments and conditions twenty-four/seven.
- Panel mounted conductivity controller 0.0-199.9 mS/cm
- An analogue controller can be configured by you to your exact process requirements.
There is no need to worry about space or cost, as all the controllers can be installed in confined spaces and the low cost means previously manual monitoring can now be automated, saving time and money.
A simple panel mounted conductivity controller designed for easy operation. The HI-8931 range should be used with the HI-8936 transmitter series. Using the correct transmitter will ensure a strong, interference-free signal at a distance of up to 300 metres (1000 feet).
The output configuration for connecting a recorder or a PLC can be chosen between 0-20 or 4-20 mA.
Use a HI-7135 electrode for in-line applications or the HI-7638 with external threads for tanks. The electrodes contain a built-in NTC sensor for temperature compensated conductivity measurements.
The controllers have large, easy-to-read displays, fire-retardant casing, electrode input, automatic alarm features, recorder output, plus dosing consent feature on ORP and pH models.
The front panel is protected behind a transparent splash-proof cover.
