Particles Plus Air Quality Monitors

Particles Plus has released its Air Quality Monitors — a line of particle counters that measure particle mass concentrations and total particle mass while monitoring and recording essential environmental conditions such as temperature, relative humidity, and carbon dioxide (CO₂) or total volatile organic compounds (TVOC).

Power management features enable the monitor to be placed into remote environments, monitoring the air quality for more than a month on a single battery charge. The sleep mode function allows the instrument to sample air and then shut down all processes for a user-defined set time. After the programmed sleep time, the unit wakes up and takes the next sample, repeating this process. Depending on the amount of time between samples and settings and the sample time, the unit can run from one to two months on a single charge.

The small, lightweight monitors are said to enhance the services provided by air quality testers and air sampling experts. The range includes the stand-alone model 7301-IAQ, which can be placed on a surface to monitor an environment for temporary testing, while the model 5301-IAQ is designed for fixed, wall-mounted installation.
