Portable 4 In 1 Multi Gas Detector Gas Analyzer for H2S CO O2 , combustible gas detector

Product Overview

Description

1,Product Description:

MDWCK200-H4  Portable pump suction four in one detector is used for rapid detection of four in one gas concentration exceeding the standard alarm. The 2.8-inch high-definition color screen is used for real-time display, and the imported well-known brand gas sensor is selected. The main detection principles include: electrochemistry, infrared, catalytic combustion, thermal conductivity, PID photoion, etc. Advanced circuit design, mature kernel algorithm processing and unique shape design. It can detect the gas concentration in the pipeline, confined space and atmospheric environment, gas leakage or high concentration single gas purity of various background gases such as nitrogen or oxygen, and detect more than 500 kinds of gases.

 

2,Functional features:

-1 ~ 4 gases can be detected at the same time, and the unit can be switched freely (the molecular weight of conventional gas does not need to be input, and the molecular weight of special gas is calculated and switched automatically). The unit can be selected: ppm, mg / m3,% vol,% LEL, PPHM, ppb, mg / L.

 

- rich man-machine interface

 

2.8-inch HD color screen, displaying real-time concentration, alarm, time, storage, communication, printing, 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 names of each menu.

 

- large capacity data storage function, supporting multiple storage modes

 

150000 data storage capacity is standard, and larger capacity can be customized; Support real-time storage, timing storage, or only save alarm concentration data;

 

It supports the local machine to view and delete data. It can also upload data to the computer through USB interface, directly analyze data, store and print data, and realize the plug and play data function.

 

- the display mode can be switched

 

Four gas concentrations are displayed at the same time, and large font circulation displays the concentration of single channel gas.

 

#standard USB charging, with charging protection function and supporting USB hot plug

 

It can be charged by computer or charging treasure, compatible with mobile phone charger; Overcharge, over discharge, overvoltage, short circuit and overheating protection; Level 3 accurate power display;

 

The tester can work normally when charging.

 

#5200ma high-capacity rechargeable battery is adopted, which can work continuously for a long time (if the battery capacity is larger, it can be explained in advance)

 

# multiple alarm modes, multi-directional three-dimensional indication of alarm status during alarm

 

It includes audible and visual alarm, vibration alarm and display visual alarm.

 

# set low alarm, high alarm and section alarm in various alarm modes.

 

# the default Chinese interface can be selected for the Chinese and English interface, with concise Chinese or English operation tips

 

# the air pump switch can be detected in real time or regularly (for the case of small measured gas volume), and the pump can be turned off to prolong the startup time.

 

# meet the design requirements of intrinsically safe circuit, anti-static and anti electromagnetic interference

 

# protection grade up to IP66, waterproof, dustproof, explosion-proof and shockproof
