The Extech MO210 pocket moisture meter is an essential diagnostic tool for investigators, field inspectors, and professionals tasked with environmental monitoring and structural resource management. This compact device allows for the immediate evaluation of whether wood, stabilized soil, or various porous components have suffered water intrusion or unwanted moisture accumulation—factors that can compromise structural integrity or promote microorganism growth. Its operation is extremely simple and intuitive: just insert the sharp pin electrodes into the material's surface to obtain a direct reading of its physical-chemical condition.
Thanks to its integrated selection switch, the instrument adapts its measurement principle based on the substrate being analyzed. In the building materials mode (such as sheetrock, wallboards, concrete, mortar, and plaster), the device accurately detects moisture levels within a range of 0.2% to 2.4%. By sliding the selector to the wood function, the portable meter calibrates its parameters to determine moisture concentrations from 6% to 44%. This versatility makes it indispensable field equipment for conservation projects, natural material optimization, and biological control in green buildings or botanical warehouses.

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.
