        Frequently Asked Questions

        Can’t find your answer? Get in touch with our team.

        • No. Whilst a monitor can initially pass the start-up process and indicate that the monitor is functional, what this doesn’t tell you is if gas can actually reach the sensor, as the sensor membranes can become clogged with muck, dust and particles that are not visible to the human eye and thus not allowing the gas molecules to reach the sensor and react in a timely fashion.

        • No, however we would suggest that you undertake a Confined Space Course which covers the use of gas monitors. Our sister company Citrus Training offers these courses.

        • Of course you can, but please try to give us as much notice as possible and ensure that you have any relevant paperwork and purchase order numbers.
