OdaLog® L2 – Gas Logger User Manual

9.3. Tools and Test Equipment

The following equipment is required to perform a calibration on an OdaLog® instrument:
 Calibration mixture: To suit sensor type (refer to Table VII). The calibration mixture should be
equivalent to 25- 50 percent of full-scale concentration, ideally near mid-scale. However, lower
concentrations are recommended for toxic gases in the interest of safety. The calibration mixture
should be certified or analysed to be accurate to at least ±5 percent of the actual labelled
concentration.
 Gas bottle regulator: To suit gas type & flow rate (refer: Table VII)
 Calibration fitting/adaptor: Complete with suitable type, size & length tubing. [Part Number 11-
0001].
 Magnetic ended Allen Tool: [Part Number: 11-0000].
 Calibration procedure document: Section 9 of this manual.
P/N: 10-1000
