Enthos Butterfly Bait Trap

$ 85.25 USD

Attract and Capture Butterflies with this Professional Bait Trap

Lightweight and Foldable Design for Efficient Field Sampling

These butterfly bait traps easily fit into backpacks for field trips. They are lightweight, weighing only 310 grams, and extremely compact—21 cm in diameter and 5 cm thick when folded. The traps are made of polyester mesh measuring 96 x 26 cm. They stand 100 cm tall and feature a side zipper opening (~90 cm) along the full length for removing captured butterflies. The trap is held open by foldable rings measuring 38 cm in diameter at the top and bottom of the black cylinder.

The conical trap includes a white funnel with a 10 cm diameter opening. A removable bait tray measuring 20 cm in diameter and 3 cm deep is supplied for use with these traps. It hangs from hooks beneath the trap cylinder. When properly attached, this tray is wind-resistant. To attach the tray to the cylinder, insert the hook through the tray hole so that the open part of the hook faces outward. An 8 cm skirt is sewn onto the bottom and can be folded to adjust the distance between the bait tray and the lower entry as needed. For a larger landing platform, simply place cardboard or hard plastic sheets at the bottom of the tray.

Key Features

• Ultra-Portable and Lightweight Design. Weighing only 310 grams with a foldable structure, it easily fits into any field backpack.
• Easy Access to Captures. A nearly 90 cm long side zipper allows quick and safe removal of specimens.
• Removable and Wind-Resistant Bait Tray. Includes a 20 cm diameter tray that secures firmly to withstand wind.
• Efficient Capture Design. The combination of a conical entry funnel and an adjustable skirt optimizes butterfly capture and retention.

Extech MO210 Moisture Detector ²⁶

$ 137.25 USD

MO210 Pocket Moisture Meter

Portable digital hygrometer with sharp pin electrodes, designed for the fast and accurate assessment of moisture levels in wood and porous building materials.

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.

Key Features

• Dual operating mode optimized for wood and porous building materials.
• Replaceable sharp pin electrodes that ensure optimal surface penetration.

Extech Video Particle Counter with Built-in Camera VPC300

$ 2,123.75 USD

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.

Key Features

• Simultaneous measurement and display of 6 independent channels of particle sizes (down to 0.3 µm).
• Built-in digital camera to capture photos (JPEG) and videos (3GP) with date and time stamps.
• Built-in meteorological sensors for direct readings of air temperature, relative humidity, dew point, and wet bulb.
• 7.1 cm color TFT LCD display with intuitive menus based on hotkeys.
