Portable methane and hydrogen sulfide detection USB interface

Waterproof, dustproof, explosion-proof, shockproof, intrinsically safe circuit design, anti-static, anti electromagnetic interference,

Passed national standard testing and CMC measuring instrument production license certification

The protection level is IP66, which can prevent rain and water splashes. Built in water vapor and dust filters to prevent moisture and dust pollution

Damaged sensors and instruments, suitable for high humidity and high dust environments

Built in pump suction measurement, integrated with water vapor and dust filters, can be equipped with professional accessories for high temperature, high humidity, and high dust environments, with rapid response; Special road design, with a sampling distance greater than 10 meters.

The 2.5-inch high-definition color screen displays real-time concentration, alarm, time, temperature, humidity, storage, communication, printing, etc

The menu interface displays information such as battery level and charging status, and uses high-definition simulation icons to show the function names of each menu

● Large capacity data storage function, with a standard storage capacity of 100000 pieces of data, and larger capacity can be customized. real-time support

Storage, scheduled storage, or only storing alarm concentration data and time, supporting local viewing of data, can also be done through

Upload data to a computer via USB or RS232 interface, and use upper computer software to analyze, store, and print the data.

● Bluetooth communication interface (optional), USB interface, RS232 interface, optional external micro Bluetooth 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 precision

Accurate battery level display, supports USB hot swapping, 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.

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 800 degrees Celsius, and can customize gas detection for higher temperatures (with optional high-temperature sampling, cooling, and filtering handles or high-temperature and high humidity pre-treatment systems)

Can simultaneously detect 1-5 gases, with unit switching freely. Conventional gases do not require input of molecular weight, while special gases require input of molecular weight to automatically detect

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 it is possible to set whether to display large values, small values, gas names, and view historical curve graphs.

The interface is selectable in both 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 selectively restore or fully restore, eliminating the worries caused by misoperation

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

Multi level calibration of target points ensures measurement linearity and accuracy, and can simultaneously comply with national and local 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
