Performance Indicators Of Flue Gas Acid Dew Point Meter

As an indispensable instrument in process heating furnaces and boilers, flue gas acid dew point meter plays a very important role. The performance indicators of the acid dew point detector are the key to evaluating its quality, so it is very necessary to choose a certified acid dew point meter product that meets the requirements.

 

 

Main performance indicators of flue gas acid dew point meter:

1. Indication error:

After calibration by the manufacturer, the uncertainty and accuracy within the measurement range reach ±0.5%.

2. Drift:

The zero drift and indication drift of the acidity dew point meter must be within the indication error limit and must not exceed the set value.

3. Repeatability:

The repeatability test is carried out under specified conditions, and the standard deviation should be controlled within 1%.

4. Reaction time:

The time from the introduction of standard gas to the display of stable value of the acid dew point detector should not exceed 60 seconds.

5. Alarm error:

Since the measured SO2 and SO3 content exceeds the standard, which may pose a serious threat to personnel health, the alarm error of the acidity dew point meter should not exceed plus or minus 10% of the set value.

 

As a device for explosion-proof areas, it is particularly important to select certified products for the flue gas acid dew point meter to ensure that its performance indicators and safety performance meet the requirements and effectively ensure production and environmental safety.
