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.
Detailed specifications on all instruments are available in the comprehensive catalog portion of this website.
|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.|
|Operating temperature range||4000 Series: 32°-120° F (0-48.9° C) ¦ LD and Multipoint models can be outfitted with thermostatic enclosures.|
