Zhongjiaohua Portable Six in One Gas Detector ZJAH-MS600 Product Overview:
The ZJAH-MS600 portable six in one gas detector is used in situations where a mobile, fast, and accurate detection of the concentration, temperature, and humidity measurement values of multiple gases on site is required, and an alarm is triggered for exceeding the standard. The ZJAH-MS600 portable six in one gas detector adopts a 2.5-inch high-definition color screen to display concentration in real time. It uses the best brands in the industry, including electrochemical or infrared, catalytic combustion, thermal conductivity, PID photoionization principle gas sensors, Swiss high-precision capacitive digital temperature and humidity sensors, advanced circuit design, mature core algorithm processing, and has obtained multiple software copyright patents and appearance patents. ZJAH-MS600 can detect gas concentrations in pipelines, confined spaces, and atmospheric environments, as well as detect gas leaks. It can detect over 500 types of gases and can also detect high concentration single gas purity with various background gases such as nitrogen or oxygen.

Zhongjiaohua Portable Six in One Gas Detector ZJAH-MS600 Product Features:

● Sound and light alarm, vibration alarm, visual alarm, undervoltage alarm, fault alarm, fall alarm (optional)
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.
● Can simultaneously detect 6-8 gases, with freely switchable units. Conventional gases do not require input of molecular weight, while special gases require input of molecular weight to automatically calculate and switch. Units available: PPM, mg/m3, Vol%, LEL%, PPHM, ppb, mg/L
Three display modes can be switched: simultaneously displaying six 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
