Product Details
In - situ Zirconia Gas Analyzer KGD - MQ - 511
Product Introduction
The In - situ Zirconia Gas Analyzer KGD - MQ - 511 is a high -
temperature analyzer for oxygen and combustible gas COe. It can
simultaneously monitor the contents of oxygen and combustible gas,
and control the combustion efficiency at an optimal level. Based on
the principles of zirconia limiting current and thick - film
catalysis, it is installed with a flange and measures gas through a
flow - guiding method. It can maintain continuous and real - time
stable monitoring in harsh environments such as high temperature
and high dust.
Product Features
- Simultaneously measures oxygen and combustible gas COe with high
precision.
- Wide measurement temperature range, up to 1500°C at most.
- The sensor is treated with constant temperature to avoid the
influence of ambient temperature and inlet gas temperature.
- The sampling probe rod is equipped with a filter and a baffle
design, enabling use under high - dust conditions.
