Eco Sensors Division of KWJ Engineering Inc. is the premier designer and supplier worldwide of low-cost ozone sensing instruments. These are used to monitor safety in the workplace, control ozone generators, monitor and control processes such as food production and storage, deodorization, sterilization, and measuring ozone dissolved in water. Our instruments are simple, user-friendly and inexpensive. We have also always designed and manufactured VOC (volatile organic compounds) instruments which continue to enjoy market acceptance. Most of our ozone related product have been the result of a client’s R&D project.
