High humidity and low sulfur flue gas analyzer

Heating solution

DetuHeating typeHigh humidity and low sulfur flue gas analyzerSolution, namelyThe testo flue gas analyzer is equipped with a testo fully heated sampling system, which includes a thermal sampling tube, a heating handle, and a fully heated sampling hose.

Full heating process:The sampling tube, handle, and hose are heated throughout the entire process to prevent condensation caused by smoke during the sampling processSO2 measurement error.

Constant temperature control:Fully heated flue gas sampling hose, length3 m， Equipped with a temperature control box, it can specify any heating temperature within the range of 50~180 ℃, achieving full temperature control without being affected by heat loss caused by environmental temperature.

Accurate measurement:The use of a fully heated sampling system eliminates the presence of smokeThe error caused by SO2 condensation can be accurately measured by using the professional flue gas analyzer testo 350.

national standard:Measurement of desulfurization backend using heating methodSO2， Meet the requirements of national standard HJ/T 397-2007.

Product advantages:

lHeated industrial flue gas sampling probes can ensure high measurement accuracy, even if the flue gas contains high concentrationsSO2/NO2 gas

lMaximum temperature resistance of sampling probe600°C

lPreheating time approximately20 minutes

leasy to operate

When the smoke contains high concentrations ofWhen NO2/SO2 gas requires high measurement accuracy, or when relevant national standards and regulations require a heated sampling system, it is recommended to use this sampling probe kit. The temperature inside the gas path of the heated sampling probe is constant and higher than the condensation temperature of water vapor, which can prevent the condensation of water vapor in the flue gas in the sampling system.

Heating typeHigh humidity and low sulfur flue gas analyzerflue gas analyzerSet, only compatible withThe testo 350 is easy to carry when used in combination.

Temperature resistance of sampling tubeAt 600 ℃, the sampling tube can be extended up to 3m in length by connecting it. The thermocouple (2.2m) can be installed inside a 2m long sampling tube for measuring smoke temperature. When the smoke at the sampling point contains a lot of dust, a pre filter can be installed at the end of the heated sampling tube.
