Useful Info and Tips for Gas Detector buyers
1.
When you buy used gas detectors, you are saving a lot of money. Gas detectors are expensive and prices keep going up. Besides that gas detectors require maintenance, calibration and sensors replacement.
2.
Sensors degrade with age, regardless if the unit was in use or not. They cost 0-0 each, depends on brand and model. Oxygen sensor degrades much faster than all others.
3.
When some sellers state that unit “works fine”, they often mean that it powers up, has sound and pump draws an air. But it doesn’t mean that all sensors are working. That may double the price you pay for the unit.
4.
Ask seller to disclose if all sensors work properly and when the unit was serviced last time. Ask seller to post a picture showing screen with actual readings. Be skeptical if sellers avoid answering these questions.
5.
Be skeptical if seller posted stock photo from manufacturer website, not actual unit he is selling. Be skeptical if seller’s description of the unit is very vague and include words like “seems to work fine”, “the unit lights up or beeps…“
6. Gas detectors sold by sellers from other countries very often have different, non US default alarm setting.
