The notice has been issued following investigations by Health & Safety Laboratory (HSL) on behalf of HSE into the Mentor PGD2, which is intended to be used for the protection of personnel entering or working in an environment where there is a possibility of flammable or toxic gas being present.
Tests and discussions with Status Scientific, the manufacturer, have determined that the low battery voltage cut-off setting may be incorrect in some instruments having an older version of software.
This older software may allow the instrument to continue to remain active when there is insufficient power for it to work accurately. In this case the indicated measurement may be below the actual gas concentration in the sampled atmosphere and the alarm may not be activated when the actual gas concentration reaches the alarm set-point.
The HSE recommends that no Status Mentor PGD2 gas meter should be used until it has been verified that the correct software version is installed and that the low battery alarm point is correctly configured in accordance with the instructions provided on the Status Scientific Controls website - click here to access.
