Four in one gas detector

Portable four in one gas detector
MS400

The MS400 portable four in one gas detector is used for portable and rapid detection of various gas concentrations, temperature and humidity measurements, and alarm for exceeding standards. The MS400 composite four in one gas detector adopts a 2.31-inch high-definition color screen to display concentration in real time. The selected gas sensor mainly detects electrochemical, infrared, catalytic combustion, thermal conductivity, and PID photoionization principles. Advanced circuit design, mature kernel algorithm processing, and multiple software works have been obtainedpowerMS400 can detect gas concentrations in pipelines, confined spaces, and atmospheric environments. It can detect gas leaks or high concentration single gas purities with various background gases such as nitrogen or oxygen, and can detect over 500 types of gases.

● Sound and light alarm, vibration alarm, visual alarm, undervoltage alarm, fault alarm, fall alarm, and multi-directional three-dimensional display of alarm status during alarm.

The alarm value can be set, and the alarm methods can be selected from low alarm, high alarm, interval alarm, and weighted average alarm

High precision temperature and humidity measurement (optional), with temperature compensation for the sensor. The instrument operates within a temperature range of -40 to 70 degrees Celsius,

Can detect gases up to 400 degrees Celsius, and can be customized for higher temperature gas detection (optional high temperature sampling, cooling, and filtering handle or high temperature and high humidity pretreatment system)

Can simultaneously detect 1-4 types of gases, with freely switchable units. Conventional gases do not require input of molecular weight, while special gases require input of molecular weight and automatically

Calculate and switch, units available: PPM, mg/m3, Vol%, LEL%, PPHM, ppb, mg/L

Three display modes can be switched: simultaneous display of four gas concentrations, large font cyclic display of single channel gas concentration, real-time curve, and each channel

The automatic or manual cycle can be switched between, and the display of MAX value, MIN value, gas name can be set. Historical record curve graphs can also be viewed.

The interface is selectable in both Chinese and English, with a default Chinese interface and concise Chinese or English operation prompts

● Data recovery function, which can selectively restore or fully restore, eliminating the worries caused by misoperation

● Zero point automatic tracking, long-term use is not affected by zero drift.

Three level calibration of the target point ensures the linearity and accuracy of the measurement, and can simultaneously comply with national standards and local metrology bureau standards.

Automatic identification and prevention of concentration calibration errors can avoid adverse effects caused by human factors.

It can detect in real-time or at regular intervals (for situations where the amount of gas being measured is relatively small), and the pump can be turned off to extend the start-up time when not detected.

● It can record calibration logs, maintenance logs, troubleshooting solutions, remind sensor life expiration, and remind the next concentration calibration time
