Online pH/ORP Meter

Online pH / ORP meters and pH / ORP controllers are one of the most common water quality analysers in use today in water treatment and process plants and yet online pH / ORP meters cause continual problems for their operators. What is needed is a stable, reliable, online pH/ ORP analyzer for a reasonable cost. That is exactly what you get with the HACH Instrument.

A pH and ORP meter consist of a pH or ORP sensor, transmitter and process adaption, combined to best suit your pH control needs. The online ORP meter from BOQU Instrument provides accurate process pH measurements in a wide range of environments, from ultrapure water to hygienic measurements in a bioreactor to dirty chemical production.

pH/ORP sensors are based on two different measurement techniques: Conventional combinational and Differential Electrode Measurement Technique (DEMT). Our range of conventional combinational sensors can withstand extreme temperatures from -5°C to 140°C. They have large reference junctions to minimize clogging problems by process media.

Unlike run of the mill pH/ORP sensors we also provide the DEMT sensor technology. These DEMT sensors provide unsurpassed accuracy, reduce reference junction fouling, and virtually eliminate ground loop problems. A field reparable model is also available to reduce downtime. These sensors are certified for use in hazardous areas too.

Our range of analyzers and transmitters come with a wide array of functional capabilities and control strategies to suit your needs.

pH / ORP has a variety of process ph analyzer and orp analyzer designed specifically for waste water, clean water, pure water, fermentation, and sterilization. PHG-2091 Online ph analyzer is popularly used for wastewater and clean water such as pulp & paper, textiles, metal plating, and heavy industries, drinking water, bottled water, farming, swimming pool, aquaculture etc. PHG-2081X is a multifunctional ph orp analyzer, widely used for pure or ultra-pure water, such as steam and water analysis systems in power plant. for food, dairy industries, brewing, Pharma, Biotech, CIP, SIP, users mainly choose pHG-2081X or VBQ online ph orp analyzer, because the temperature compensation can be up to 130C and with FDA certificate. On the other hand, VBQ Online pH meter warranty is 1 years.

The economical PRO-P3 Transmitter is easy to use with its menu-guided user interface. The NEMA 4X enclosure can be panel, wall, pipe, or integral sensor mounted. The interface is identical to GLI's 33-series analyzers. Versatile 2, 3, or 4-wire hookup capability. Isolated 4 - 20 mA output. The transmitter is also passcode protected.
