Designed for ease of use, whether you are an air quality consultant, safety engineer, maintenance manager, or just concerned about total volatile organic compound (TVOCs) in your environment. Our Baseline VOC-TRAQ II detector is an excellent way to monitor and record PID detectable TVOC`s. Based on the latest Baseline piD-TECH eVx photoionization sensor, the VOC-TRAQ II is both compact and economical. It has no moving parts and operates using the simplicity of diffusion, yet still offers a fast response time. Eight (8) different detection levels between two lamp energies offer a broad range of detection capabilities.
