CALIBRATION GAS CYLINDER

CALIBRATION GAS

R134a, CO2 / R744

The calibration gas cylinder is mainly used for the calibration, adjustment and periodic verification of fixed or portable atmosphere monitoring detectors.

In the same range:

For sensitivity verification of sniffer leak detectors, rather than concentration calibration in ppm, the FT 92-T test leak delivers a leak rate of 5 g/yr of HFC, HFO, HC refrigerant gases or H2/N2 tracer gas.

Calibration gas in a disposable, single-use cylinder, compliant with ISO 6141.

Available for the following gases:

R134a, CO2 / R744 and other gases on request.

Concentration:

R134a, value 500 or 1000 ppm
CO2, value 500 or 1000 ppm

Delivered with an analysis certificate.

Use	For the calibration, adjustment and periodic verification of fixed or portable atmosphere monitoring detectors. The cylinder must be fitted with a compatible flow/pressure regulator.
Concentration	R134a: 500 or 1000 ppm. CO2: 500 or 1000 ppm. Other values on request.
Gas	R134a, CO2 / R744. Other gases on request.
Delivered with	Cylinder delivered with an analysis certificate.

Usage tips

Bump test and calibration: a bump test checks that the alarm works, not that the measurement is accurate. A strongly desensitised sensor can still trigger the alarm; only calibration reveals this drift.

Choice of regulator: a diffusion detector is calibrated using a fixed-flow regulator, at the flow rate recommended by the detector manufacturer, and a calibration cap. The gas must be applied until the reading stabilises, which can take several minutes with some sensors.

Calibration gas or calibrated leak: a leak is expressed as a flow rate (g/yr), a concentration in ppm. Calibration gas is used to calibrate atmosphere monitoring detectors, which measure a concentration in a room; sniffer leak detectors are checked with a test leak or a calibrated leak.
