Low cost gas detector are not necessarily poor quality. Each manufacturer goes into a different segment. For example, MSA enters the expensive segment, the machine has many high-end features such as water resistant, high sensor life, integrated motion alarm sensor and Bluetooth to connect the phone. In contrast to MSA, BW Technologies chose the basic segment, their machine criteria are just to measure gas, a pop-up button, and then turn it off.
When comparing machine prices, users should compare brands, quality, features and price. Some gas detector are cheap, but they offer very high prices, or sellers sell high. Therefore, once again affirming, cheap is not necessarily inferior and expensive is not necessarily good.
In addition, some handheld gas detector are made in China but are labeled Korean or American. Buyers should thoroughly learn about the manufacturer before placing an order.
