Excellent, my order arrived in Piura, Peru, exactly in 18 days, thanks to the supplier. Now I have to send the equipment for calibration due to a certification issue that companies require for confined spaces, but everything works well from there. I will continue buying from you. Thank you.

The device works perfectly, but the shipping is a disaster. It was supposed to be delivered on 28.02, but the shipping will only happen on 25.02. There was a delay in providing information about the shipping; it could have been done on 13/14.02. This is customer service from Oberhausen, Germany.

Every thing works fine. Good and fast detection. Also ex levels.
I could not check H2S, as I have no source for that.
Pity that the pump does not fit in de case with the gas detector.
Minor issue is the poor hose: it was so strong bend, that the diameter collapsed. Any hose works fine.
Good value for money. Happy with the instrument.
