• Measures free or total chlorine using EPA-approved colorimetric DPD method
• User-selectable cycle times
• Two user-selectable alarms
• 4 to 20 mA and RS-485 with Modbus output
The monitor uses economical and reliable colorimetric DPD (N,N-diethyl-p-phenylenediamine) chemistry to measure either free or total chlorine up to 10 mg/L. Measurement cycles can be set between 90 seconds up to 10 minutes for reagent and control optimization. Measurements are preceded by a zero measurement to compensate for color of the sample. The monitor features a scaleable 4 to 20 mA output and RS-485 with Modbus, as well as two user-selectable alarm relays.
The monitor is housed in a NEMA 4X (IP66) corrosion-resistant enclosure that comes ready to surface mount. The enclosure has a transparent cover that allow direct view of the measured value as well as the sample chamber and removable cuvette.
Sample to the unit is provided by user-supplied 1/2" OD semi-rigid or rigid tubing that connects by a push-to-connect fitting at pressures of 1 to 200 psi. The sample drain is a 1/2" hose barbed fitting; order drain hose separately. The monitor accepts 100 to 240 VAC, 47 to 63 Hz power input,;order power cord separately below or directly hard wire. Monitor does not include dry chemical reagents; order separately. |
