The peracetic acid sensors are available in two configurations: flowcell and submersion. The Constant-Head Flowcell is used to maintain a constant flow rate and pressure at the face of the sensor. The only requirement is that the sample inlet flow rate be at least 7 gallons per hour. A Low Volume Flowcell is available for clean water application with a flow rate of 1-3 gallons per hour. The submersion sensor requires flow velocities of at least 0.4 ft/sec for proper operation.

Available in loop-powered transmitter, AC operated analyzer, or battery operated portable versions, the Q45H/85 is well suited for almost any peracetic acid measurement requirement. Even a portable data-logging version is available for temporary installation or process studies. And for even more flexibility, the instrument is available with an optional pH sensor input that allows a single unit to provide both peracetic acid and pH analog outputs.
