It can be a good way to cover if you're doing a lot of non-methane hydrocarbon work, but it has some serious drawbacks:
1. You need to reprogram the monitor to accept Pentane calibration gas instead of Methane. This means you need to buy a separate part and connect it to a computer, or send it in to a service shop. 2. You'll need to remember in the field that you're seeing 2x the Methane that is present in the room. Most customers we see run into Methane 98% of the time, so we don't recommend it to them. 3. The Pentane Simulant calibration relies on the correlation factors of the monitor, and these can change or degrade with time, giving you more inaccurate results. 4. You're no longer following manufacturer dictated guidelines, so you may fall out of warranty coverage. 5. If a person other than you goes to calibrate your Quattro using standard BW 4-gas mix they'll mess up the calibration, so you need to take meticous notes on what you're using to calibrate and train anyone that uses the detectors. On Quattros, unless you're seeing Pentane or other gases like it very frequently, I'd recommend just following the manufacturer recommend calibration gas settings. Usually we tell people to stick with the Methane as recommended, and just remember and advise employees that there may always be up to double the gas than what you see at any given time.
