AIR QUALITY MONITOR PCE-PCO 2 is a portable handheld particle counter used to monitor particulate matter (PM) concentrations in the air. Designed to aid in indoor air quality (IAQ) assessments, this particle counter also measures formaldehyde air temperature, dew point and relative humidity.   The PCE-PCO 2 particle counter is ideal for monitoring clean rooms, exposure to exhaust, smoke and other harmful air pollutants, and levels of airborne combustible dust such as agricultural dust, carbonaceous dust, chemical dust, metal dust, plastic dust and wood dust. A variety of materials are explosive in dust form. Some examples include: food (e.g., candy, sugar, spice, starch, flour and feed), grain, tobacco, plastics, wood, paper, pulp, rubber, pesticides, pharmaceuticals, dyes, coal and metals (e.g., aluminum, chromium, iron, magnesium and zinc). These materials are used in agriculture, chemical manufacturing, pharmaceutical production, furniture, textiles, fossil fuel power generation, recycling operations, metal working and processing (including additive manufacturing and 3D printing) and many other industries and processes.   In addition to being a combustion hazard, certain kinds of dust can be a health hazard. Exposure (such as skin contact, eye contact and inhalation) can be linked to sneezing, a stuffy or runny nose, itchy or red eyes, headaches, fatigue, fever, cough, shortness of breath, dermatitis, asthma, bronchitis, pneumonia (e.g., Legionnaires’ disease and hypersensitivity pneumonitis) and cancer. When inhaled, PM 2.5 and PM 10 particles can settle deep into the lungs and result in damaging health effects. Since the PCE-PCO 2 particle counter monitors PM 2.5 and PM 10 particles, the device has many practical health and safety applications. Heating, ventilation and air conditioning (HVAC) technicians use PM 2.5 and PM 10 particle counters for HVAC system performance and filtration audits. In addition, industrial hygienists and workplace safety professionals rely on PM 2.5 and PM 10 particle counters when evaluating occupational health and safety risks related to hazardous and combustible dust.   - Captures 6 particle sizes - Measures air temperature, dew point and relative humidity - 2.8" TFT full-color LCD screen - Built-in camera for image and video recording - Cumulative, differential and concentration particle counting modes - Stores up to 5,000 data sets to memory - Power-saving automatic shutdown feature - PM channels: PM 2.5, PM 10 - Free software download on PCE Software web page   Particle specifications   Particulate matter channels PM 2.5 / PM 10 Particle concentrations 0 ... 2000 μg / m³ Resolution 1 μg / m³     Particle counter specifications   Particle sizes (in micrometers) 0.3 / 0.5 / 1.0 / 2.5 / 5.0 and 10 μm Flow rate 2.83 l / min Coincidence error < 5 % at 2,000,000 particles per cubic foot Counting efficiency 50 % at 0.3 μm; 100 % with particle size > 0.45 μm Memory capacity Stores up to 5,000 data sets Counting modes Cumulative, differential, concentration       Temp. and humidity measurement specifications   Air temp. measuring range 0 ... +50 °C / +32 ... +122 °F Dew point temp. measuring range 0 ... +50 °C / +32 ... +122 °F Humidity measuring range 0 ... 100 % RH Air temp. accuracy +10 ... +40 °C / +50 ... +104 °F: ± 0.5 ° Others: ± 1 ° Dew point temp. accuracy 0 ... +10 °C / +32 ... +50 °F: ± 1 ° +10 ... +40 °C: / +50 ... +104 °F ± 0.5 ° Humidity accuracy 0 ... 20 % RH: ± 5 % 20 ... 40 % RH: ± 3.5 % 40 ... 60 % RH: ± 3 % 60 ... 80 % RH: 3.5 % 80 ... 100 % RH: ± 5 %     General device specifications   Operating conditions 0 ... +50 °C / +32 ... +122 °F, 10 ... 90 % RH, non-condensing Storage conditions -10 ... +60 °C / +14 ... +140 °F, 10 ... 90 % RH, non-condensing Display 2.8", 320 x 240 pixel, backlit, TFT full-color LCD screen Power supply 1 x rechargeable battery Battery life Approx. 4 hours of continuous operation at full charge Battery recharge time Approx. 2 hours using AC charger   Complette Package: 1 x PCE-PCO 2 particle counter 1 x zero filter 1 x rechargeable battery 1 x AC charger 1 x USB cable 1 x user manual 1 x mini tripod 1 x hard case
