Portable Infrared Natural Gas Calorific Value Analyzer KGD - MQ -
515 Product Introduction The Portable Infrared Natural Gas Calorific Value Analyzer KGD - MQ
- 515 adopts non - dispersive infrared (NDIR) gas analysis
technology with independent intellectual property rights. It can
simultaneously measure the calorific values of coal - bed methane
and natural gas, as well as the volume concentrations of multi -
component gases such as CH₄ and CₙHₘ. Product Features - Simultaneously measures gas components and calorific values: It can
simultaneously measure the volume concentrations of multi -
component gases such as CH₄ and CₙHₘ, and automatically calculate
and display the calorific values of coal - bed methane and natural
gas, replacing the combustion - type calorific value meter.
- High measurement accuracy: Using non - dispersive infrared gas
analysis technology, there is no cross - interference among multi -
component measured gases. The accuracy of natural gas calorific
value can be ensured by accurately measuring the concentration of
CₙHₘ, and CₙHₘ has no interference on the measurement result of
CH₄.
- Portable body design: Easy to carry, it can meet the needs of both
on - site industrial measurement and laboratory airbag sampling
analysis.
- Simple data management: Automatically stores measurement data, with
query and deletion functions, and can transmit data to the superior
centralized control system through multiple interfaces.
- Intelligent power management: Equipped with a soft - start power
switch to prevent the instrument from operating under low - power
conditions.
- Low cost of use: Compared with gas analysis technologies such as
Orsat and chromatography, the measurement process does not require
disassembly and installation, consumption of chemical reagents,
etc. It is easy to operate and has no consumables.
