Information available in ppm & percent solution ranges
With a versatile dual-parameter measurement range capability, the HP80 hydrogen peroxide analyzer from Electro-Chemical Devices is a highly flexible and reliable instrument designed to measure H2O2 in both the parts per million (ppm) range and the percent solution range to support a variety of process applications.
The HP80 analyzer is an easy-to-use measurement solution that is ready to go out of the box with a plumb-and-play design—a single technician can set it up in less than 15 minutes with no special tools. It is a complete analyzer system including an H2O2 sensor, a pH sensor, a constant head flow control device and a transmitter with power supply, all mounted on a PVC wall panel that is ready to hang.
The HP80 analyzer features amperometric H2O2 sensors that are manufactured with a gold cathode, a silver anode and a rugged microporous membrane. They are smart sensors with identity and calibration information stored internally. Communication between the T80 transmitter and the sensor occurs via Modbus. The sensors are flow sensitive, requiring a minimum flow rate of 0.5 ft per second; above this flow rate, the reading is virtually independent of the flow rate.
A constant head flow control device (CFD) maintains the optimum flow rate moving past the sensor for sampling purposes. The CFD’s automatic flow control capability eliminates the need for pressure regulators and rotameters, which many other H2O2 analyzers require, to reduce system maintenance and life-cycle operating costs. The minimum flow rate required by the CFD is 10 gal per hour, and the maximum flow rate is 80 gal per hr, with the sample draining at atmospheric pressure.
