Extech Video Particle Counter with Built-in Camera VPC300

VPC300 Video Particle Counter

6-channel environmental particle counter with color TFT LCD display, built-in camera for photo and video recording, and NIST-traceable calibration certificate.

The Extech Instruments Model VPC300 Video Particle Counter is an advanced diagnostic and environmental monitoring scientific instrument, essential for indoor air quality (IAQ) assessment, cleanroom verification under ISO standards, and filtration system optimization in conservation and environmental protection projects. Equipped with an internal controlled-flow pump and an isokinetic probe, this field device allows for the precise quantification of airborne particulate matter concentration (such as dust, smoke, mold spores, and chemical byproducts) that alter the balance and comfort of enclosed ecosystems and biological research laboratories.

One of the most innovative features of the VPC300 is its built-in 320 x 240 pixel camera, which captures JPEG images and 3GP videos of the exact sampling points. This visual evidence directly correlates with the collected physical data, facilitating the precise localization of airborne pollution sources. The meter features a 74 MB internal memory capable of storing up to 5,000 full records and 20 minutes of video, externally expandable via a Micro-SD card. Thanks to the included PC software, researchers can download the collected information through the USB interface to process statistical data and structure professional analytical reports based on historical pollution profiles.

Beyond particle analysis, this comprehensive measurement equipment simultaneously monitors critical climate variables such as air temperature and relative humidity, automatically calculating dew point and wet bulb temperature values. These metrics are fundamental in environmental studies, as the combination of high relative humidity and temperature drops serves as a predictive indicator for mold colony formation and the degradation of sensitive organic materials. Its 7.1 cm color TFT LCD display incorporates a color-coded alert scale (green for low counts, yellow for moderate levels, and red for hazardous concentrations), ensuring an immediate visual diagnosis during field assessments.
