Portable Coal Gas Analyzer KGD - MQ - 513 Product Introduction The Portable Coal Gas Analyzer KGD - MQ - 513 adopts non -
dispersive infrared (NDIR) gas analysis technology with independent
intellectual property rights, long - life electrochemical sensing
technology, and MEMS - based thermal conductivity technology. It
can simultaneously measure the calorific values of coal gas and
biogas, as well as the volume concentrations of gases such as CO,
CO₂, CH₄, H₂, O₂, and CₙHₘ.
Product Features - Simultaneously measures gas components and calorific values: It can
simultaneously measure the volume concentrations of gases such as
CO, CO₂, CH₄, H₂, O₂, and CₙHₘ, and automatically calculate and
display the calorific values of coal gas and natural gas, replacing
the combustion - type calorific value meter.
- High measurement accuracy: No cross - interference among multi -
component measured gases: CₙHₘ has no interference on the
measurement result of CH₄, and CO, CO₂, and CH₄ have no
interference on the measurement result of H₂. It is less affected
by the outside world, and the change of gas sampling flow has no
impact on the measurement result of the H₂ thermal conductivity
sensor. Measuring the volume concentration of CₙHₘ ensures the
accuracy of the calorific values of gases such as coke oven gas,
mixed gas, producer gas, and straw gas.
- Portable body design: Easy to carry, it can meet the needs of both
on - site industrial measurement and laboratory airbag sampling
analysis.
- Intelligent power management: Soft - start power switch and
intelligent battery power management avoid the instrument from
operating under low - power conditions.
- 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.
- 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 has a simple structure, is easy to operate, and has no
consumables.
