Datasheet: MicroDPD™ Chlorine Residual Analyzer

Source: Severn Trent Services

The MicroDPD analyzer uses proven DPD colorimetric technology for monitoring chlorine in both municipal and industrial applications. The instrument may also be used for controlling a pump or a valve via user selectable alarms or when used in conjunction with a 1450 or 1451 controller to provide residual control. It meets EPA guidelines for direct reporting to state agencies.

The MicroDPD has many superior features over competitive instruments. The 0-10ppm range allows for diverse applications. When above 10 ppm, the display will flash indicating an out of accurate range condition but it will continue to trend up to 20ppm. The measurement signal is forwarded to a monitoring device using either the 4-20 mA output or RS485 Modbus.

This on-line instrument is ideal for accurately monitoring and controlling free and total chlorine residuals up to 10ppm. The MicroDPD allows operator to view the color measurement, and comes fully assembled and calibrated. One-year maintenance kit, RS485 sample strainer and other accessories included.
