多气体分析仪

7901DN4气体分析仪，用于连续热处理和工业工艺过程，单一气体分析仪，甲烷，壁挂式，防护等级NEMA4（IP65）
The Nova 7900 Series Heat Treat Analyzer System utilizes high stability infrared detectors for the simultaneous measurement of CO, CO2, and CH4. In addition, the analyzer can also be supplied with a non-consumable, long life thermal conductivity cell for hydrogen that is compensated for the interference effects of CO, CO2, and CH4.This ensures that Hydrogen will always read correctly regardless of the background gas composition. A long life electrochemical sensor is used for PPM or % O2 analysis. In most cases, sensors are installed in a temperature controlled box to improve reading accuracy. All detected gases have a separate digital readout and linear recorder output. Various versions available for either exothermic or endothermic mixtures, or for other industrial process gases.

The Nova 7900 Series Heat Treat Analyzer System utilizes high stability infrared detectors for the simultaneous measurement of CO, CO2, and CH4. In addition, the analyzer can also be supplied with a non-consumable, long life thermal conductivity cell for H2 that is compensated for the interference effects of CO, CO2, and CH4. This ensures that H2 will always read correctly regardless of the background gas composition. A long life electrochemical sensor is used for PPM or % O2 analysis. All sensors are temperature controlled or tempeature compensated for maximum stability. All detected gases have a separate digital readout and linear recorder output. Various versions available for either exothermic or endothermic atmosphere gases, or for other industrial process gases. Calculations can be displayed such as gas ratios and heating value of flammable gases.

7900P-4E便携式气体分析仪，用于热处理及其他氢基工业生产过程，四气体分析仪，氧气，二氧化碳，甲烷及氢气
The Nova Model 7900P Series Heat Treat analyzers utilize a three channel high stability infrared detector for the simultaneous measurement of CO, CO2, and CH4 in exothermic or endothermic gas mixtures. In addition, the analyzer can be supplied with a fully compensated thermal conductivity cell for H2. A separate O2 detector can also be supplied for measuring low (PPM) or percent levels of oxygen in the atmosphere gas stream. Dew point is detected by a dielectric ceramic sensor and is available in standard and low ranges. All detected gases have a separate LCD digital readout and a linear recorder output. The customer may choose any combination of gases to be measured.

The 7900P series analyzers are complete with integral sampling pump, rechargeable battery, filters, flow meter, and sampling hose. Solenoid valves are used to isolate low range dew point and O2 sensors during purges and when analyzer is not in use to prevent ambient air contamination of the sensors and greatly reduce purge time during start-up.
