FTB 92-T

TEST LEAK WITH RESERVOIR

R1234ze

The FTB 92-T test leak is intended for checking the sensitivity of on-site and workshop refrigerant gas leak detectors.

In the same range:

When a gas cylinder is already available, the FT 92-T test leak connects directly to it (¼ FL valve); it is available for R134a, R1234ze, R1234yf, R513A, R290, R600a and H2/N2.

Compatible with:

The FTB 92-T test leak with its built-in R1234ze reservoir enables quick sensitivity verification of portable refrigerant gas detectors: DXR 240 and HRD 92 SC.

For checking the sensitivity of on-site or workshop refrigerant gas leak detectors.
Connected directly to its own R1234ze reservoir.

Usage tips

Effect of temperature: the leak rate is given at 20 °C. As the pressure of R1234ze increases with temperature, a leak exposed to a higher temperature has a leak rate above its nominal value.

Probe positioning: the probe is placed facing the leak orifice, without blocking it, sheltered from air currents.

Orifice cleanliness: the leak orifice must never be touched with the fingers or blocked with a plug; no grease or other substance should be allowed to enter it.
