DESCRIPTION OF THE PHD-4
The PHD-4 portable leak detector permits fully
automatic detection of concentrations of helium down
to a lower limit of 2 parts for million (ppm).
The value of the leak is shown in real time on the
graphic display on the front panel.
The instrument, which emits an acoustic signal
proportional to the concentration of helium detected,
incorporates a self-test program, making it possible to
carry out any type of operation using the soft-keys on
the front control panel. The operator can use the straps
provided to carry the unit and locate leaks using the
extensible probe.
