Multi-Parameter Analyzer

4 TO 8 SENSORS The Insite Instrumentation Group MPA 48 multi-channel analyzer is a unique system that combines ad- vanced electronics with the latest in sensor technology. The analyzer will accept any combination of DO, SS, pH, or ORP sensors and automatically configure for the correct operation. The system allows for flexi- ble and economical process monitoring and control. The DO sensor does not need membranes, fill solu- tions, nor replaceable sensor caps. The SS sensor is based on near infrared technology, eliminating inaccu- racies caused by changes in the process color. The pH electrodes are flat glass, double reference junction Optical Dissolved Oxygen—Suspended Solids—pH—ORP—Any Sensor Combination FLUORESCENCE DISSOLVED OXYGEN —THEORY OF OPERATION A very specific energy wavelength is transmitted to a ruthenium compound immobilized in a sol-gel matrix. The ruthe- nium will absorb this energy, changing the outer electron’s energy level. The electron will then collapse back to it’s original energy state, emitting the energy as a photon with a different specific wavelength. This is called fluorescing. If the intensity of the transmitted wavelength is tightly controlled, the amount of fluorescing is both predictable and re- peatable. If oxygen molecules are present the amount of fluorescing is reduced, referred to as fluorescence quench- ing. By measuring the amount of quenching it is possible to determine the amount of oxygen present.

The ORP elec- trodes are flat glass, double reference junction. Both pH and ORP electrodes feature a quick dis- connect design that makes changing electrodes a snap and reduces down time due to electrode main- tenance. Measuring Range DO — 0 to 25 ppm SS — 0 to 30,000 mg/l pH — 2 to 12 pH ORP- +/- 2000mV Accuracy DO — 1% of reading or .05 ppm, whichever is greater SS — 3% of reading Sensitivity / Resolution DO — .01 ppm below 4.00, .1 ppm above 4.0 SS — 1 mg/l below 1000 mg/l 10 mg/l between 1,000 and 9,999 mg/l 100 mg/l above 10,000 mg/l Repeatability DO — .01 ppm SS — +/- 1% Sensor Drift DO & SS — Less than 1% per year Temperature Range DO & SS — 0 to 60 degrees C pH & ORP — 10 to 100 degrees C Response Time 95% in less than 60 seconds Sensor Check Automatic self diagnostics Outputs Up to 8 Opto-isolated 4-20 milliamp (one for each channel) Optically isolated RS-485 Modbus RS-232 serial Up to 8 dry contact 10 amp relay setpoints (one for each channel) 1 alarm relay 1 clean relay Memory Backup Yes Display Backlit graphical LCD display with UV protection Contrast adjustment via keypad Continuously displays all channels Sensor Cable Length 33 feet standard (optional lengths up to 2000 ft) Ambient Temperature minus 20 degrees C to 70 degrees C Ambient Humidity 0 to 100 percent Enclosure Rating NEMA 4X Wetted Materials Epoxy, polyurethane, glass, and PVC Maximum Pressure 100 psi MPA 48 SPECIFICATIONS Insite Instrumentation Group e-mail - info@insiteig.com Website– www.insiteig.com OR CONTACT YOUR LOCAL TECHNICAL REPRESENTATIVE AT:
