Brief Introduction

Characteristics of MS600 Toxic and Harmful Gas Detector:


Waterproof, dustproof, explosion-proof, shockproof, intrinsically safe circuit design, anti-static, anti electromagnetic interference, passed national standard testing and CPA type certification for measuring instruments

Protection level IP67, can withstand rain and short-term immersion, built-in replaceable water vapor and dust filters, can be used in high humidity and high dust environments without damaging sensors and instruments

Built in pump suction measurement, fast response, sampling distance of more than 10 meters, special gas path design, optional accessories can detect negative or positive pressure of -0.5 to 2 kilograms of gas, without affecting the measurement results

The high-definition 2.5-inch color screen displays real-time information such as concentration, alarm, time, temperature, humidity, storage, communication, printing, battery level, charging status, etc. The menu interface uses high-definition simulation icons to display the function names of each menu

● Large capacity data storage function, customizable for larger capacities. Optional SD card storage function, supporting real-time storage, timed storage, or only storing alarm concentration data and time, supporting local viewing and deletion of data, and can also upload data to the computer through USB, infrared communication, RS232 interface, and use upper computer software to analyze, store, and print data. Support remote wireless transmission (optional function)

● Infrared communication interface (optional), USB interface, RS232 interface automatic recognition, optional external micro wireless infrared printer, printing: company name, gas name, date and time, environmental temperature and humidity, concentration data, test results (whether qualified)

● USB charging interface, can be charged with a computer or power bank, compatible with mobile phone chargers, overcharge, overdischarge, overvoltage, short circuit, overheating protection, 5-level accurate power display, supports USB hot plugging, and the detector can work normally during charging

Adopting a 6000mAh high-capacity rechargeable polymer battery, it can work continuously for a long time

Sound and light alarm, vibration alarm, visual alarm, undervoltage alarm, fault alarm, and multi-directional stereoscopic 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 and can detect gases up to 1300 degrees Celsius (optional high temperature sampling, cooling, and filtering handle or high temperature and high humidity pretreatment system)

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 be selected to simultaneously detect 1-6 types of gases, up to 8 types of gases, and the units can be freely switched. Conventional gases do not require input of molecular weight, while special gases require input of molecular weight to automatically calculate and switch. Units can be selected: PPM, mg/m3, Vol%, LEL%, PPHM, ppb, mg/L

Three display modes can be switched: simultaneously displaying four gas concentrations, large font cyclic display of single channel gas concentration, real-time curve, automatic or manual cycling between channels can be switched, whether to display maximum value, minimum value, gas name can be set, and historical record curve graphs can be viewed.

The interface can be switched between Chinese and English, with a default Chinese interface and concise Chinese or English operation prompts. Users of all ages can easily operate it

● Data recovery function, which can be selectively restored or fully restored. Automatic identification and prevention of concentration calibration errors to avoid adverse effects caused by human factors.

● Zero point automatic tracking, multi-level calibration of target points to ensure measurement linearity and accuracy. Can simultaneously comply with national standards and local metrology bureau standards

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