Technical Parameters:

1. 19-inch instrument rack, including oxygen, carbon dioxide and carbon monoxide analyzers
2. The oxygen analyzer is an oxygen analyzer that uses the method of measuring the change of paramagnetic pressure to detect the
oxygen concentration in the gas. Response time (T90) 3.5 s, internal signal processing time < 1 s, pressure sensor (internal)
50~200 kPa, zero drift< 0.5%/month of the minimum measuring range on the nameplate, 0.5%/month of the measured value drift < the current measuring range, repeatability error < 1% of the current measurement range, 1% of the current measurement range of the
minimum detection limit, linearity error < 1% of the current measurement range
3. The carbon dioxide analyzer and carbon monoxide analyzer are non-discrete infrared type, and the principle is based on the fact
that gas molecules have a specific infrared absorption band, and the single-beam alternating infrared analysis method is adopted.
The minimum detection limit is 1% of the current measurement range, the linearity error measurement is ±1% of the full scale of <
when the maximum range is in the maximum range, the repeatability is < ±1% of the minimum range on the nameplate, and the response
time (T90 time) is approximately 1.2 L/min of the sample gas flow< 30 seconds
4. The range of oxygen analyzer is 0-25%, the range of carbon dioxide analyzer is 0-10%, and the range of carbon monoxide analyzer
is 0-1%
5. The temperature controller is used to control the cold trap, and the water is fully removed during the gas refining process of
the test
6. The double-head pump for gas sampling can transfer the gas samples generated during combustion to the analyzer about 30 meters
away
7. Data acquisition system (including operation and control procedures)
8. The acquisition board adopts 16-bit wide gain range, analog and digital I/O boards
9. Thermocouple type: K type, range: ambient temperature ~ 1500 degrees Celsius.
10. The data acquisition system can collect data through the installation and activation of data loggers or field pointers
11. The data acquisition system is composed of the following parts:
Bit thermocouple input module, 16-bit analog input module, digital input/output module, 12-bit analog output module, 4 and 8-slot
base plate, connection base, network module, power supply 24 volt 5A DC universal power input, data acquisition computer, printer
