PHG-2081Pro
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 BOQU 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.
