The PC-5000 series six-channel particulate meter recently introduced by GrayWolf Sensing Solutions (Shelton, Conn.) is a modified version of the portable PC-4005 launched last year. The wall-mounted monitor optionally incorporates sensors for additional environmental parameters such as total volatile organic compounds (TVOCs), carbon dioxide (CO2), temperature and relative humidity. The device displays and logs calculated particle mass concentrations while simultaneously displaying and logging all installed optional sensors.
A long-life laser diode-powered sensor and a precision brushless internal pump enable reliable particulate measurement down to 0.3 microns. A high-accuracy photo-ionization detector (PID) for TVOC measurement and a dual-wave NDIR CO2 sensor, both optimally suitable for indoor air quality (IAQ) applications, are offered.
The PC-5000 series monitors may alternatively be connected to GrayWolf’s AdvancedSense®, DirectSense® or WolfPack®. These instruments cover additional parameters (e.g., formaldehyde, ozone, carbon monoxide, nitrogen dioxide, ammonia and more) logging into the same data file as other connected sensors. This also allows the user to take full advantage of the broad range of features offered by GrayWolf such as on-board educational info, including help videos, IAQ particle size charts, government/industry particulate guidelines and more.
The PC-5000 series wall-mount particle/mass monitors may integrate into a building automation system using Ethernet, USB, RS232 or (optional) wireless 802.11 b/g or RS485. Access readings are effected via Modbus RTU or (optional) cloud-based GrayWolfLive™. PM1.0, PM2.5, PM10 and other particle mass size ranges may be concurrently displayed and logged. These monitors measure particles sized from 0.3 µm to 25 µm with a flow rate of 2.83 LPM (0.1 CFM). The monitors can display six particle count size ranges simultaneously: 0.3µm, 0.5µm, 1.0µm, 2.5µm, 5µm, 10.0µm are standard. Alternative size “binning” is available as an option.
