The MS4810-Monitor is based on double wave length measuring principle photometer, Usually uses one beam by modulation system.
One single default absorption line without interference is chosen in the near infrared spectral range. A single mode diode NIR operating around room temperature scans this single absorption line continuously to get real time measurement. Then calculate the concentration of specified substance by professional mathematic. Automatic corrections for temperature and pressure variations are included(need extra Pressure sensor, or order separately ).
· Process liquid analysis
· Industry chemical process
· Research and Process optimization
· Applicable for Liquid with suspended particles less than 28.8mg/L;
The rugged industrial design and periodically purging make the NIR Gas Analyzer easy to maintain. There are no moving parts in the instrument and none of consumables are needed during normal operation.
All critical parameters are monitored continuously and warning messages are given if maintenance is required beyond the recommended maintenance intervals.
Reliable measurement was assured by the special reference system. Exact reference standard is fixed. Unless it is not stable, you need not any calibration for this system.
Periodically correction is good for extern contaminants overcome.
The routine maintenance interval is three of months.
The MS4810 Monitor is easy to install and operate. Several model structure were designed for variety of industry.
The TR transducer is one unit integrity, can be used for most case; Inserting the sensor part into sample container or pipeline where suitable, and fixing the instrument with attached flange.
The TA model consists of 3 basic units: Transmitter unit,. receiver unit and electronics unit.
The transmitter and receiver units are mounted directly to the process device across against each other of the transmitter and receiver by DN50/F165 flanges. These are going to be used for high pressure or temperature system only.
There are no moving parts in the instrument, thus preventative maintenance is limited to visual inspection and cleaning of optical windows.
Purging to prevent dust from collecting on the optical windows maybe needed for very dirty system. Experience shows that a three months preventative maintenance interval is sufficient for most applications without special contaminants.

Detection limit: Refer to Table 1
Min. measuring range: Refer to Table 1.
Max range: Refer to Table 1.
Dynamic range: 100 to 10000 :1
Instrument span drift: < 4% of measuring range between maintenance intervals
Instrument zero drift: Negligible (<2% of measuring range between maintenance intervals)
Maintenance interval: Recommended every 3 months (no consumables needed)
Calibration: Not deeded in general running. In situ with flow through cell, or in separate calibrationsample.
Analogue output: 0/4 - 20 mA current loop, 500 Ω max. the range to be sent can be set by user. And any parameter can be chosen to send .
Digital output: RS 232 or RS485 by protocol of Modbus or STIMcom
Relay output: High gas relay (normally closed-circuit relays)
Warning relay (normally closed-circuit relays)
Fault relay (normally closed-circuit relays)
Analogue input: Optional 0/4 - 20 mA.(for flow meter, or pressure sensor in special application suit )
Ambient temperature: -20C to +55C
Maximum Sample Pressure: <1Mpa or 10 bars abs for general model. High pressure system under requirement;
Maximum Sample Temperature:

Standard mounting: DN50/PN10, F165
Alignment tolerances: Flanges parallel within 1° with <1m light path(AR Model only).
Purging of air: Dry and oil-free pressured air or gas, or by fan. The pressure of purging air must be 0.1 kgf/cm2 higher than that of samples in pipe.
Cooling air: adjust the flow to assure the temperature inside sensor is lower than 70 °C, this temperature could be read by instruments. In the case of high temperature application, cooling air must be guaranteed to supply continuously, once stop longer than seconds might damage the sensor. It was recommended to select AR model for high temperature application if possible.
