Entech HDSTM Personal Monitors

Introducing the latest HDSTM (Helium Diffusion Sampling) Personal Monitor from Entech. A breakthrough technology based on helium diffusion yields a sampler that is small, light weight, cost-effective, universal, and defensible. HDSTM Personal Monitors simplify the collection of chemicals in the workplace and deliver highly reliable results unaffected by factors that create errors in other diffusive samplers – such as matrix concentrations, varying humidities, and fluctuating face velocities.
