OPTICAL PARTICLE COUNTERS
MET ONE HHPC 6+ HANDHELD PARTICLE COUNTER
MET ONE HHPC 6+ handheld optical particle counter is suitable monitoring of controlled environments and mini-environments, easy filter leak troubleshooting for particle-contamination issues, spot-checking critical areas, and targeting particle generation within process equipment. It has up 6 channels detection and the range of particle detection is from 0.3 μm to 10.0 μm.
GRAYWOLF PARTICLE COUNTER 3500
PC-3500 is a stand-alone optical particle counter that measures the concentration is the size range of 0.3 μm to 25.0 μm with 2.83 LPM flow rate. It can measure up to 6 channels of simultaneous data and it can approximate mass concentration in μg/m³ with density and refractive index corrections, including PM2.5, PM10 and TSP.
METONE PARTICLE COUNTER 804
Met One Instruments’ 804 handheld optical particle counter is a 4-channel portable particle counter that counts particles 0.3 microns to 10.0 microns. The unit is configurable, allowing you to choose your particle sizes of interest from seven sizes: 0.3, 0.5, 0.7, 1.0, 2.5, 5.0 or 10.0 microns.
NONDISPERSIVE INFRARED CO2 SENSORS
HOBO® MX CO2 Logger (MX1102)
The HOBO MX CO2 data logger records carbon dioxide, temperature, and relative humidity (RH) data in indoor environments using non-dispersive infrared (NDIR) self-calibrating CO2 sensor technology and integrated temperature and RH sensors.
HOBO Data Logger U12-012
The instrument can record real-time temperature, relative humidity and light intensity. It can also record CO2 data when connecting with Telaire 7001 via CO2 cable.
TELAIRE 7001
The Telaire 7001 handheld carbon dioxide sensor features patented Absorption Infrared technology. Each sensor measures CO2 (0-2500 ppm) and temperature with quick response and can calculate and display real-time ventilation rates. It is capable of estimation of ventilation rate per person of measured rooms.
OTHER MULTISENSORS
GRAYWOLF ADVANCEDSENSE PRO
Is a moderately accurate sensor with high response, which is suitable for both quick walk-through surveys and for long term IAQ trending in real buildings. It can detect CO2, CO, TVOCs, relative humidity, air temperature, SO2, NO2 and formaldehyde.
OCCUPANCY SENSORS
HOBO® Occupancy/Light Data Logger (UX90-005x/-006x)
The HOBO Occupancy/Light data logger monitors room occupancy up to 5 or 12 meters away (depending on the model) as well as indoor light changes with its integrated sensors. Using HOBOware®, you can easily configure both channels to record occupancy and light on and off conditions for building energy audits.
