Toshcon Controllers and Sensor Inputs
Toshcon dosing is often paired with a controller that reads water quality and drives the pump. Inputs (select any two sensors, digital, analog or ISE):
- pH: analog or digital
- Chlorine sensor: potentiometric or ISE
- Conductivity / total dissolved solids: analog or digital
- Dissolved oxygen: optical, digital type
- Turbidity: optical, digital type
- Sludge level: optical, digital type
- UV-VIS sensor (any one): COD, BOD, TOC, TSS, nitrate, nitrite or colour. Operates in a spectral range of 200 nm to 750 nm with built-in colour and turbidity compensation.
- Ion selective electrode: analog
- Total suspended solids: IR based
Outputs: 2 x 4-20 mA active output (500 ohm maximum load).

Are you an authorized Toshcon dosing pump dealer in India?+
Yes. QuaSys Inc. is an authorized dealer for Toshcon dosing pumps and supplies them across India. Call +91 95408 15659.
What is a solenoid driven dosing pump?+
It is a diaphragm pump powered by an electromagnetic drive. It has no gland, gives excellent proportional control and, when installed and operated properly, needs no maintenance.
What is the price of a Toshcon dosing pump?+
QuaSys Inc. does not publish fixed prices online. A Toshcon pump is quoted by model, pressure, wetted material and control features. Share your dosing requirement. Call +91 95408 15659 for a specification-based quote.
Which Toshcon TJ-MD model do I need?+
Models 8 to 100 cover about 6 to 90 litres per hour at their maximum pressure. The right model depends on your flow, back-pressure and chemical, so send us those details.
Can a Toshcon pump be controlled by a PLC or a sensor?+
Yes. The pump accepts an external 0/4...20 mA control signal and a level-control connection, and Toshcon controllers can read pH, chlorine, conductivity and other sensors.
