The smallest detectable leak rate of the Ecotec E3000 for helium is 1 x 10
-6
mbar l/s
(higher than for refrigerant).
You can use a PRO-Check calibrated leak for the internal calibration of helium.
Because the PRO-Check calibrated leak does not fit into the opening on the front
panel of the Ecotec E3000, you have to connect it with a SUB –D cable, see
installation manual of the ECO-Check.
If you are working with diluted helium, you can have the determined leak rate also
displayed as the gas-equivalent leak rate. For further details, see "Gas equivalent to
helium and hydrogen, settings for diluted gas [}46]."
Special features with
hydrogen / forming
gas
If you are sniffing for hydrogen / forming gas, the Ecotec E3000 needs longer for an
analysis than with refrigerants. Therefore stick to the following minimum measurement
times.
Length of sniffer line Minimum measurement time
3m 2.7s
5m 3.0s
10m 3.8s
15m 5.0s
Table8: Minimum measurement times for hydrogen
If you work with hydrogen (forming gas), you can have the determined leak rate also
displayed as gas-equivalent leak rate, see "Gas equivalent to helium and hydrogen,
settings for diluted gas [}46]."
If you want to verify hydrogen, the warm-up phase of the device must be extended to
1hour before the first calibration.

Methane Methane cannot be calibrated with the built-in ECO-Check because methane can be
detected only on mass 15 (which is outside the range for the permissible internal
calibration from 40 to 105).
Therefore use the external calibrated leak “TL4-6 for methane” for calibration.
