M-900H Combustion AnalyzerDetailed product description：

Characteristics of M-900H Combustion Analyzer:

Adopting a high-end carrying case, it is small in size, portable and sturdy (300 × 160 × 190mm).
Adopting microcomputer technology, the instrument has functions such as self checking and automatic calibration; The instrument adopts a fully Chinese interface to achieve human-machine dialogue and automatically prompt the working status and operation steps of the instrument.
Adopting a new generation of imported sensors, it has fast response, high accuracy, good stability, and long service life.
The oxygen sensor can be used for about 2 years, and the CO sensor has a lifespan of about 5 years.
The instrument is equipped with a rechargeable battery, which can work continuously for 6-8 hours when fully charged. It can also work directly with an AC 220V power supply.
The unique "step frequency response" technology greatly improves the response speed of the instrument, which is 2-3 times faster than similar products. The test can be completed in about 30 seconds at a time.
It can randomly store 510 sets of on-site test data, and can also be equipped with an external printer to print test data in real time.
The instrument is equipped with an RS232 communication port, which can be connected to a computer for analysis of test data and printing of reports through configured software. All M-series products can be optionally equipped with desktop or laptop computers.
The instrument has six combustion options including natural gas, city gas, liquefied gas, heavy oil, light oil, and coal, and is suitable for detecting flue oxygen; The instrument can directly calculate and display CO '(CO α=1); It is also suitable for testing gas appliances.
The instrument has multiple configuration combinations and can simultaneously measure various parameters such as gas and flue gas temperature and pressure. Users can choose according to their needs.
