The Tech Center >The Common Specifications

(Applicable to all instrument configurations)

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]
Linearity:	±1.0% of full scale
Zero Drift:	±1.0% of full scale (24 hours)
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.
