Specification parameters are defined per ANSI/ISA—51.1—1979 (R1993). Performance of a particular model may vary from these specifications, and may also be influenced by environmental factors. For further data, please consult the factory.
| Accuracy: | Analog units: ±2.0% of full scale Digital units: ±2.0% of reading, ±1 least significant digit (Limited to accuracy of calibration standard) |
| Repeatability: | ±0.5% of full scale |
| Minimum Detectability: | 1.0% of full scale [Better on certain digital models] Note that any data obtained at the level of minimum detectability will not be accurate. |
| Linearity: | ±1.0% of full scale |
| Zero Drift: | ±1.0% of full scale |
| Span Drift: | Less than ±2.0% of full scale (24 hours) The zero and span drift specifications assume that the analyzer is equilibrated, and is at constant temperature, with a properly maintained sensor. “Drift” is defined as an undesired change in output over a period of time, which change is unrelated to input, operating conditions, or load. |
| Lag Time: | Less than 1 second |
| Calibration: | Against standard gas mixture, or via INTERSCAN’s Electronic Calibration Service |
| Compliance with EC Directives on RoHS and WEEE: |
Compliant. Refer to detailed information. |
