Condition: Good condition, checked and calibrated
CleanAir Europe offers the reconditioned Ametek 921 analyzer for SO2 gas analysis. It is housed in a single 19-inch rack-mounted unit. It can be integrated into EMC systems or used alone for a variety of gas monitoring applications. The Model 921's design with no moving parts was specifically developed to enable the high sensitivity and low concentration measurements required by the latest environmental regulations.
The Model 921 can be configured to measure most UV absorbing gases. The optional low range white cell offers a longer path length for measuring lower concentrations. For example, the minimum full scale for SO2 is 25 ppm, with an accuracy of 1% of full scale. The simple, rugged design of the Model 921 is complemented by powerful data processing capabilities.
Key points:
- No noise pollution
- Accuracy better than 0.25 ppm SO2
- Excellent baseline stability, minimal range drift
- Linearity less than 1% over 4 ranges
- No interference from H2O and CO2
