Product Description
The detector adopts a 2.31 inch high-definition color screen for real-time display. MS104K is built in imported high performance electrochemical, infrared, catalytic combustion, thermal conductivity, PID gas sensors and high-precision capacitive digital temperature and humidity sensor. Advanced circuit design, mature kernel algorithm processing, unique shape design, has obtained a number of software work patents and appearance patents.Main FeaturesThe measurement unit can be switched freely. (no need to input molecular weight for conventional gas, input molecular weight of special gas, the detector will automatically calculate and switch)
Units optional: ppm, mg/m3, Vol%, LEL%, PPHM, ppb, mg/L.
Diffusion measurement.
Human-machine interface.
2.31 inch high-definition color screen, display real-time concentration, alarm, time, temperature, humidity, storage,
communication, power, charging status, concentration unit, gas molecular formula, gas name and other information, the menu interface uses high-definition simulation graphics to display the function names of each menu.
Large-capacity data storage function, support multiple storage methods.
Standard configuration of 100,000 data storage capacity, larger capacity can be customized; SD card storge is optional, support real-time storage, timing storage, or only alarm concentration data and time. Support local view and delete data, also can upload data to computer through USB, use upper computer software to analyze data, store and print. RS485 is optional.
Three display modes can be switched.
Simultaneous display of four gas concentrations, large font cycle display of single channel gas concentration, real-time curve. Automatic or manual cycle between channels are switchable. Can set whether to display the maximum value, minimum value, gas name, and view the historical curve graph.
Graphical display to reflect the trend of gas concentration change in a curve in a period of time.
Data recovery function.
Partial or full recovery can be selected, eliminating worries caused by wrong operation.
Can set whether to display the maximum value, minimum value, average value.
USB charging interface, with charging protection function, support USB hot plug.

2100mAh large-capacity rechargeable polymer battery, it can work continuously for a long time.
High-precision temperature and humidity measurement (optional).
It can do temperature compensate to the sensor at same time.
Support real-time detection or timing detection.
When not detecting, you can turn off the pump to extend the working time.

Contains sound and light alarm, vibration alarm, visual alarm. Alarm types include: concentration alarm, under-voltage alarm, and fault alarm.
Alarm value can be set, multiple alarm mode settings.
Low level alarm, high level alarm, interval alarm, weighted average alarm.
Mis-operation recognition function.
Mis-operation of concentration calibration can be automatically identified and prevented, which can avoid the defects caused by human factors.
Zero point automatic tracking, long-term use is not affected by zero drift.

Chinese and English interface for selection.
Logging
Record calibration log, maintenance log, troubleshooting measures, sensor life reminder, reminder for next concentration
calibration.
Intrinsically safe circuit design.
Anti-static, anti-electromagnetic interference, passed the national standard test and CMC measuring instrument production license.
Protection grade up to IP65, water-proof, dust-proof, explosion-proof, shock-proof.
