Gas Monitors

Gas checks prior to entering a confined space can be carried out by lowering your gas monitor via a drop line.  If this is not suitable you can purchase a monitor with a built in pump and connect a long small hose to be inserted into the space.  The type of gas monitor you require is obviously dependentPreview Changes (opens in a new tab) on your needs.  ALL 4 gas monitors are configured to detect the two most common toxic gases,  hydrogen sulphide (H2S) & carbon monoxide (CO); they look for the flammable gas of methane (CH4) and they measure the actual level of oxygen (O2).

If you have other gases that may be present, you may need to buy an additional single gas monitor for that gas, or see if you can have your four gas monitor changed to include that gas.  Remember that if you change it, you will need to remove one of the toxic sensors.

We also calibrate your gas monitors, which is required six monthly.

We also supply five gas monitors and PID Gas monitors… see below.

Remember staff using gas monitors need to be trained in their proper use.  We can provide that training..
