FD-4S

Does the job.

I am vetting inspector working on board ocean going Petroleum and Gas ships. As a part of my job and to be a good role model to the ships crew, I carry this personal gas detector with me. I bought it 3 months ago. It works perfectly. Battery - I use it for about 3 hours every ship and it lasts about 3 ships ebfore recharging. I also like that it has a usb recharge and no need to carry a separate bulky charger. It clips on the boiler suit pocket. It also looks very stylish. It does the job from the safety point of view. It arrived with a calibration document valid for 12 months. I highly recommend it.

Very nice product, can definitely compete with the more known brands. It keeps up very well. Battery life is satisfactory it keep stamina a full day. We use it in a HVAC setup, to enter steam/hot water boilers. cleaning, repairs (refractory, tube repairs) and inspection of the boilers. So you got an idea what conditions we expose it to.

My normal unit failed in the field and I purchased this unit with overnight delivery. I opened the package, and found a well built unit that was easy to use, calibrated (with certificate) and ready to charge. I used it the following day and I am hear to tell you about it, so it must have worked, or at least I was in an area where I was safe, and ensured that it was safe due to this product. The only thing I might mention in a negative fashion was, in direct sun light the screen was difficult to read, but in my Sump and indoors, I could read it easily. I was able to complete my work thanks to this product. Carl

I was in a bind looking for a 4X monitor to use at a job site for a site engineer. I did some research and chose this one instead of another major brand. For half the price, this is a great option. It's not just a compliance item, but a reliable tool people can use with trust.

I was worried when I bought it because of the price tag, I didnt want to buy some knock off trash that I could have spent 100$ on. I wanted quality. I knew it worked when I breathed on it and it warned me every time. I trust this and will be taking it with me while cave exploring.

Worked well, but battery failed less than a year from purchase. I cannot even get any charge to stay when plugged in. I wrote website for help and to inquire about 1-year warranty. Have not heard anything back. Please contact me to resolve. Thank you.

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.

Very good gas meter. Quality and reliable product. Happy to use.

Ya solo funciono 2 semanas y ya lo hace las lecturas , tubimos una fuga de gas y nunca la detecto

Funktioniert gut..... Leider kostet es noch mal extera Zoll (ca. 70 Euro).
