Series-04 Personal Single Gas Detectors

Product Features

Cost of Ownership:

Disposable gas detectors are low cost but users can suffer high failure rates, this can result in safety concerns. Users often find the cost of ownership often outweighs the small initial cost saving over a reliable renewable gas detector. Customers constantly have to replace failed units resulting in personnel down time and the lost productivity.

Applications

Facilities such as oil refineries, petrochemical storage facilities, water and wastewater treatment plants, pharmaceutical labs, Utilities, Fire-fghting and Chemical Plants are hazardous areas. workers and visitors need personal gas protection at all times without the addition of extra bulky equipment. Personal Single Gas Monitors are ideal for this.
