A standard pH sensor placed in ultrapure water does not measure the pH of the water. It measures a drifting, unstable number that is influenced by the sensor’s own reference...

Auto-Dosing Unit
Compact Dosing, Built to Run Unattended
An Auto-Dosing Unit (ADU) pairs a peristaltic dosing pump with a timer, controller, or programmable circuit board inside a single, wall-mountable enclosure. The peristaltic pump moves chemical by compressing a flexible tube against a rotor — a simple mechanism with no seals or check valves in contact with the fluid, which suits viscous, corrosive, or particulate-laden liquids well. The controller decides when and how much to dose: on a repeating schedule, on a signal from host equipment, or from a live process reading.
Peristaltic dosing — a rotor compresses a flexible tube to move chemical, so no pump seals are exposed to the fluid being dosed
Timer or controller-driven — dosing follows a programmable schedule, an external signal, or a live pH/ORP/chlorine reading, depending on the application
Compact and self-contained — pump and control electronics share one IP65-rated enclosure, ready for wall mounting near the point of use
Four application types — Self-Service Laundry, Enzyme Dosing, Dishwashing, and Swimming Pool, each matched to its own dosing profile

All Application Types
Peristaltic Pump + Controller
Self-Service Laundry ADU
Dosing units for coin-op and self-service laundromats, dispensing detergent and softener into each wash cycle on a timed or signal-triggered basis. Multi-pump controllers run several wash programmes from one unit.
Peristaltic Pump + Controller
Enzyme Dosing ADU
Timed enzyme dosing for grease traps and drain lines in commercial kitchens, breaking down FOG (fats, oils and grease) and keeping lines clear. A weekly programmable timer schedules dosing automatically, with no daily intervention required.
Peristaltic Pump + Controller
Dishwashing ADU
Dual-pump dosing units for professional dishwashers, metering detergent and rinse aid independently, each set to match wash chemistry and rinse-cycle requirements.
Peristaltic Pump + Controller
Swimming Pool ADU
Digital pH, ORP and free-chlorine dosing controllers for pool water treatment, using dosing pumps driven by live probe readings to keep pool chemistry within range automatically.
