T9280C Online Silicate Monitor
I. Characteristics and technical parameters
2.1 Features:
- Adopt photoelectric metering dosing method, which can achieve 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, save 5 years of measurement data;
- 7-inch touch type colour LCD screen, intuitive operation and display;
- 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.

II. 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 silicate monitoring have also been greatly improved. For this reason, the company launched the T9280C on-line silicate analyser, which adopts photoelectric metering and dosing method, cold light source spectroscopic measurement, and no dead-volume reaction pool, which ensures the accuracy and reliability of the instrument measurement. The external structure of the instrument is shown in the figure.
