Extech VPC260 : 6-Channel Particle Counter

The VPC260 is a 6-channel particle counter for monitoring workplace environmental health and quality. Measure up to 6 channels of particle sizes plus air temperature, relative humidity, dew point, and wet bulb. Check indoor air quality for exhaust, smoke, respirable crystalline silica dust (RCS), airborne combustible dust, and other harmful air pollutants. General Air Temperature 0°C to 50°C (32°F to 122°F); Accuracy: ±1.8°F (±1.0°C) Coincidence Loss 10% @ 2,000,000 counts per ft³ Counting Efficiency 50% @ 0.3 µm (100% for particles >0.5 µm) Dew Point 0°C to 50°C (32°F to 122°F) Max Flow Rate 0.035 ft³/min (1.0 L/min) controlled by internal pump Particle Size 0.3 µm, 0.5 µm, 1.0 µm, 2.5 µm, 5.0 µm, 10 µm Readout Modes Cumulative, Differential, Concentration Relative Humidity 0 to 100% RH; Accuracy: ±3.5% RH (20% to 80% RH) Size [L × W × H] 238 mm × 73 mm × 50 mm (9.3 in × 2.8 in × 2.0 in) Storage Capacity 1000 data sets Wet Bulb 0°C to 50°C (33°F to 122°F)
