Extech VPC300 Video Particle Counter with built-in Camera

Extech logo

Measure up to 6 Channels of Particle Sizes plus Air Temperature and Relative Humidity

The Extech VPC300 is a Video Particle Counter with built-in Camera. Measures up to 6 channels of particle sizes plus air temperature and relative humidity. Used for capturing videos and photos that are stored onto internal memory or a micros card. The VPC300 can measure up to 6 channels of particle sizes plus air temperature and relative humidity.

Microscopic fragments of mold or other airborne particles can be inhaled causing health impacts, so sampling the air during and after mold cleanup may make sense to determine how effective the process has been at removing or containing these contaminants. Restoration professionals sometimes use a particle counter to determine the level of airborne particles. Use the included software to generate reports with videos, photos and data points. Complete with NIST-traceable calibration certificate, Universal AC Adapter/Charger with multiple plugs, USB cable, PC software, tripod, filter, 7.4V NiMH battery and a hard, protective case.

Using the Extech VPC300 – Particle Counter Considerations

Particle pollution is a mixture of various components including smoke, dust, chemicals, mold, and gases. Particle concentrations can affect our health and comfort levels.  Evaluating the quality of the air by determining the concentration and size of these particles can help to determine if a problem exists.  Locating the source of these various particles can help to determine effective methods of reducing these and improving the Indoor Air Quality (IAQ).

One way to determine the source of air particulates in a room is to test the air outside of the room under investigation.  Determine the concentration and size of particulates at the air intake to that room.  Purge or Zero the particle counter and then measure the concentration and size of particles in multiple areas of the room to be tested, to determine the effectiveness of the incoming air filtration.  The air temperature, relative humidity, and CO2 levels are also an important consideration for IAQ as high humidity and lower temperatures can bring about mold creation.

If a room is classified as an ISO clean room or clean zone, the counts of particle sizes for that class cannot be exceeded when tested.    Refer to the ISO Clean Room Class chart (ISO 14644‐1:1999) for values.

The VPC300 is equipped with a still/video camera to directly see the areas under test. Data, images, and video can be stored on up to an 8GB micro‐SD card (not included) or in the meter’s internal 74MB memory.

The life of the meter can be maximized by testing only when necessary and securely storing the instrument when it is not in use. Continuous use is not recommended and can shorten the life of the instrument especially in dusty environments. Setting up a common sense maintenance schedule and testing to the schedule will go a long way in lengthening the life of the instrument sensor.
