"ATIs Model Q45H\/84 Hydrogen Peroxide Monitor is designed to continuously monitor processes that utilize hydrogen peroxide for bleaching or disinfection purposes. 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 Q45H\/84 is available in two flowcell configurations. 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 Sealed Flowcell is available for applications with lower flow rates.","Available in loop-powered transmitter, AC operated analyzer, or battery operated portable versions, the Q45H\/84 is well suited for almost any hydrogen peroxide measurement requirement. Even a portable data-logging version is available for temporary installation or process studies."
