FCH 99M-PVA
ADJUSTABLE CALIBRATED LEAK
R134a, R1234ze, R1234yf, R32, R410A, R600a, R290, CO2, H2/N2
The FCH 99M-PVA adjustable calibrated leak is intended for sensitivity checking and calibration of production and laboratory leak detectors operating by sniffing at atmospheric pressure.In the same range:
For refrigerant gases R134a, R1234ze, R1234yf, R32, R290, R600a, the FCE 24-PVA-DR adjustable leak features a built-in dual reservoir (expansion chamber + liquid gas reservoir) for standalone use. For gases such as helium, argon, H2/N2, H2 or CO2, the FCH 99M-PVA-R150 adjustable leak with its built-in reservoir is the most suitable option.
Compatible with:
The FCH 99M-PVA adjustable calibrated leak enables calibration of multi-gas production detectors: MTD 920 and MTD 930.
- Leak rate adjustable over a range depending on the applied pressure.
- Designed to be supplied with gas in the “dry” vapour phase.
- Connects directly to a gas cylinder fitted with a suitable pressure regulator, via a ¼ FL adapter valve.
- Delivered with a calibration certificate and a pressure/leak rate curve.
Available for:
- R134a, R1234ze, R1234yf, R32, R410A, R600a, R290, CO2, H2/N2
Use | The FCH 99M-PVA is an adjustable continuous-flow leak that must be supplied with gas in the “dry” vapour phase. Connects directly to a gas cylinder fitted with a suitable pressure regulator, via a ¼ FL adapter valve. |
| Leak rate | Leak rate adjustable between approx. 1 and 10 g/yr [±20%] depending on the applied pressure. The adjustment range depends on the version of the leak and the type of gas. Other values on request. |
| Gas | R134a, R1234ze, R1234yf, R32, R410A, R600a, R290, CO2, H2/N2. Other gases on request. |
| Delivered with | Leak delivered with its calibration certificate valid for 1 year and a pressure/leak rate curve. |
