Hanwei gas detector originate from China. More than 10 years ago, TES Industry used to import to check the quality before selling to the market, but we stopped immediately because the quality did not meet our requirements.
Hanwei has been the fastest growing force in recent years. Its products range from single-gas detector, 4-gas detector, detect to 6 gases, and fixed gas detector. In particular, its packaging is very beautiful, industrial goods that are packed as gifts!
Last! If you need some advice, we recommend that customers use a European or American gas detector at a price that is not much more expensive than the Hanwei Gas detector.
