T9282C Online Phosphate Monitor
I. Overview
With the improvement of the specified standards of power plants and the requirements of desalination and water purification projects, the timeliness and accuracy of phosphate monitoring have also been greatly improved, especially the low phosphorus treatment technology that is basically implemented at present, and the accuracy of the measurement of the low content of phosphate is more important. The company launched the T9282C type phosphate analyser, using photoelectric metering dosing method, cold light source spectroscopic measurement, no dead volume reaction pool, thus ensuring the accuracy and reliability of the instrument measurement.
II. Characteristics and technical parameters
2.1 Features:
- Adopt photoelectric metering dosing method, accurate measurement;
- Cold light source spectroscopic measurement, extending the service life of the light source;
- Automatic adjustment of the light intensity of the light source, light source attenuation can also ensure the accuracy of the instrument measurement;
- Automatic control of reaction temperature, constant temperature measurement and calibration;
- Large-capacity memory, can save 5 years of measurement data;
- 7-inch touch type colour LCD screen, operation and display are more intuitive;
- 4-channel isolated current output, configurable to any channel, any range or PID;
- 4-channel relay output, which can be configured to over-limit alarm, broken sample alarm or system failure alarm;
- RS485 interface for remote data monitoring;
- Queryable curve and measurement alarm in any time period.
