Product Name: gas detector
Specification and model: ms400
Ms400 series portable composite gas detector is used to quickly detect various gas concentrations and ambient temperature and humidity measurement, and alarm will be given if the measurement exceeds the limit value. Ms400 adopts a 2.31 inch high-definition color screen for real-time display, and uses industry-famous gas sensors. The main detection principles are: electrochemistry, infrared, catalytic combustion, thermal conductivity, PID photoion, etc. Advanced circuit design, mature kernel algorithm processing, unique shape design, has obtained a number of software works and appearance patents. Ms400 is suitable for detecting gas concentration in pipeline, confined space and atmospheric environment; gas leakage or purity of single gas with high concentration of nitrogen or oxygen as background gas. More than 500 kinds of gases were detected.
It can detect 1-4 kinds of gases at the same time, and the units can switch freely
Units: ppm, mg / m3, vol%, LEL%, PPHM, ppb, mg / L.
Built in pump suction measurement, integrated water vapor and dust filter, fast response, support long-distance sampling
The built-in water vapor and dust filter can prevent the sensor and instrument from being damaged by water vapor and dust, which can be used in high humidity and high dust environment;
The sampling distance is more than 10 meters, special gas path design, can be directly detected; negative pressure or positive pressure - 0.5-2kg gas, the measurement results have no impact.
Rich man machine interface
The 2.31 inch high-definition color screen displays real-time concentration, alarm, time, temperature, humidity, storage, communication, power, charging state, concentration unit, gas molecular formula, gas name and other information; the menu interface uses high-definition simulation graphics to display the function name of each menu.
Large capacity data storage function, supporting a variety of storage methods
Standard configuration of 100000 data storage capacity, larger capacity can be customized; support real-time storage, fixed time storage, or only store alarm concentration data; support the local machine to view and delete data, or upload the data to the computer through USB interface, and use the upper computer software to analyze the data, store and print.
High temperature gas detection (optional)
The selection of high temperature sampling cooling filter handle or high temperature and high humidity pretreatment system can detect the flue gas at 400 ℃. Higher temperature gas detection can be customized.
Three display modes can be switched
Four kinds of gas concentration can be measured (according to customer requirements) and displayed at the same time. The concentration of single channel gas can be displayed circularly in large font, and real-time curve display can be achieved.
The change trend of gas concentration in a period of time is reflected in the form of curve.
Data recovery function, partial or full recovery can be selected to avoid worries caused by misoperation.
Whether to display the maximum value, minimum value and average value can be set
Standard USB charging, with charging protection function, supports USB hot plug, can be charged by computer or power bank, compatible with mobile phone charger; has overcharge, over discharge, overvoltage, short circuit, overheating protection; 5 levels of accurate power display; the detector can work normally when charging.
It adopts 4500ma high capacity rechargeable polymer battery, which can work continuously for a long time
High precision temperature and humidity measurement (optional)
It supports real-time detection or timing detection, and the pump can be turned off to extend the startup time when it is not detected.
Multiple alarm modes, multi-directional and three-dimensional indication of alarm state
It includes sound and light alarm, vibration alarm and display screen visual alarm. Alarm types include: concentration alarm, undervoltage alarm and fault alarm.
Multiple alarm mode settings
Low alarm, high alarm, interval alarm, weighted average value alarm.
● misoperation identification function
The misoperation of concentration calibration can be automatically identified and prevented, which can avoid the adverse effects caused by human factors.
Zero point automatic tracking, long-term use is not affected by zero drift
The multi-level calibration of target points ensures the linearity and accuracy of measurement
Chinese and English interface can be selected
Wide working temperature: - 40 ～ + 70 ℃, supporting temperature compensation
Record calibration log, maintenance log, troubleshooting countermeasures, sensor life expiration reminder, next concentration calibration time reminder function.
