Review: Quality gas meter - Very good gas meter. Quality and reliable product. Happy to use.
Review: PRODUCTO NO VALIDO PARA EUROPA - este producto no esta certificado con normativa ATEX europea. Esta prohibida su distribucion y venta en Europa, engañan al decir que tiene calibracion europea.. esto es verdad. viene con esta calibracion, pero no con la certificacion. a la hora de devolverlo es practicamente imposible , faltan sus datos como el nif , el email de la persona de contacto de la devolucion y por supuesto admiten la devolucion a portes que corren por tu cuenta. por otra parte la factura viene desde USA y no desde Grecia (UE) que es su centro de logistica europeo por tanto tambien te comes el IVA. NO PUEDEN VENDERLO EN EUROPA Y LA DEVOLUCION LA HACEN IMPOSIBLE.

## Questions & Answers

**Q: when measuring oxygen readings, can you set a range of time, duration or frequency for data logging?**
A: Great question, see video for a detailed answer.

**Q: will this unit pick up propane and natural gas leaks during a home inspection?**
A: This is not made to pick up leaks during a home inspection. What would be more appropriate is a gas leak detector with GOOSE NECK. The gas leak detector is more sensitive (in ppm) range where this detector is a LEL % detector, for exposure safety purposes.

**Q: Does this 4 gas detector come with a clip to attach to my FR shirt?**
A: The detector has installed on its back a belt clip. Thanks

**Q: Is there a calibration kit available?**
A: The detector comes with a calibration cap to be plugged into calibration gas.
 For calibration, a standard mixed gas NIST gas bottle with a regulator will work very well. Our recommended product is ASIN: B015O16X32.
Multi Calibration Gas: 25 PPM Hydrogen Sulfide, 100 PPM Carbon Monoxide, 2.5% (50% LEL) Methane, 19% Oxygen, Balance Nitrogen
