- Neutralization systems
System Overview
The BL-981411-0 continuously measures pH using a connected electrode and activates external control equipment, such as dosing pumps or valves, to maintain the desired pH level. This ensures stable process conditions and reduces the need for manual adjustment.
What's Included
- BL-981411-0 panel-mounted pH controller
- Mounting hardware
- Instruction manual
Measurement Method
The pH is measured using a glass electrode connected to the controller. When the measured value deviates from the setpoint, the relay output activates external dosing equipment to adjust the pH level accordingly.
Why Choose BL-981411-0?
- Compact and easy-to-install solution
- Reliable pH control for continuous processes
- Ideal for panel integration in existing systems
- Cost-effective control solution

Description
Description
Mini panel-mount pH controller 12 volt supplied with wall brackets & 12vdc adapter.
**Please ask for HI-75220VAC when planning to use in Europe, and ask that HI-12VDC be removed.**
Adjustable Dosing Relay
The BL981411 features a dosing relay which may be configured to dose above or below a user programmable pH setpoint.
Selectable Overdose Protection
The mini controller may be programmed to deactivate a valve, pump, or connected device if its activation continues over a selected time; adjustable from 5 to 30 minutes.
Selectable Control Override
With the flick of a switch, normal “Auto” operation may be overridden turning your connected device “Off” from operation or always “On.”
Fuse Protected Dosing Contacts
The mini controller is protected for up to a 2A load from a connected pump or device.
Easy Peripheral Connection
Quick-connect terminal blocks provide for easy connection to power, communication, dosing control, or sensors.
Matching Pin Connection
An included matching pin option helps protect the sensor from ground loop effects that may lead to erratic readings or system damage.
Mains powered - All mains operated equipment is compatible with UK AC voltage and frequency – 230V, 50Hz.
Interchangeable Electrode - One controller for all jobs thanks to HANNA’s wide range of interchangeable electrodes. Simply change the electrode for the task ahead.
