"ATIs Model Q45H\/85 Peracetic Acid Monitor is designed for on-line monitoring and control of processes the contain peracetic acid. Q45H systems utilize a membrane-covered polarographic sensor that does not require the addition of chemical reagents. The Q45H system has no moving parts, so there are no pumps or motors that burn out or tubing breaks that create maintenance nightmares. All normal maintenance items are included with each system.","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."
