ROC pH/ORP-5500 series pH ORP online transmitting controller
This series instruments are widely used for online pH/ORP monitoring in environment protection water treatment, pure water treatment, industrial process and so on.

This series instruments are widely used for online pH/ORP monitoring in environment protection water treatment, pure water treatment, industrial process and so on.

Single stage RO controller used for conductivity monitoring and process program control .

Suitable for large residential/light commercial applications
Fully adjustable, 5-cycle control delivers controlled upflow backwash, downflow brining and slow rinse, rapid rinse, timed brine refill and downflow service
Backwash capacity handles tanks up to 24″ diameter
Mechanical control (7- or 12-day clock or metered initiated regeneration)
Valve body is solid, lead-free brass
Time tested, hydraulically-balanced piston, seal, and spacer concept to pilot service flow and regeneration

Widely used for online measurement of acid&alkali in low concentrations and the low viscosity single-phase fluid of non-trade settlement process.

On-line analysis and process control of the oil refining, metallurgy,chemical synthesis industry process;

Meter and time dual mode, the meter mode, its inflow meter achieved all station can be set according to the water volume demanded , as long as set by the swap of tank volume (L) backwash water and wash water, set cycle running water volume(ton), according to the set value for each station after descending to the switch when the “0”, discontinued or no water stop decreasing and maintain. This series of products have beautiful appearance, high material precision of valve body parts, good strength and high temperature resistance, and the main valve body is connected with metal inserts with good maintainability.

Easily-adjustable, 5-cycle, downflow-brining control
Rugged, long-life construction features a lead-free brass valve body
Uses conditioned water for regeneration

Digital Laser Turbidity online analysis sensor,It can be used for on-line monitoring of water quality in different water bodies such as waterworks and membrane filtrate,The sensor internally completes all measurement calculation compensation

Widely used for online measurement of acid&alkali in low concentrations and the low viscosity single-phase fluid of non-trade settlement process.
