Echo Meter Touch 2 PRO Bat Detector ²⁵

$ 451.20 USD

Turn Your Mobile Device into a Professional Bat Detector

Detect, listen to, and identify bats in real time with the Echo Meter Touch 2 PRO: professional precision in the palm of your hand.

Echo Meter Touch 2 PRO transforms your smartphone or tablet into an advanced acoustic bat detection tool. Designed specifically for researchers and environmental consultants, this device offers high-fidelity recordings with reduced noise and more captured bat calls. Compatible with Android (USB-C or Micro-USB) and featuring a free app, it's ideal for field monitoring without an internet connection. Includes real-time listening modes, interactive spectrogram, geolocation, and automatic species suggestions powered by Bat Auto-ID technology.

Signal-to-Noise Ratio (SNR)

SNR measures the loudness of bats relative to background and electronic noise in a given audio recording. A high-SNR bat detector is preferable as it allows for capturing quiet or distant echolocation calls. This chart compares the SNR of the EMT 2 PRO and EMT 2 at different frequencies. Since the EMT 2 PRO has a higher SNR, it is more likely to trigger and record high-frequency bats (above 60 kHz).

Sensitivity and Noise

This chart shows the microphone sensitivity and electronic noise produced by the EMT 2 PRO and EMT 2 across the recording bandwidth. The difference between the two values determines the signal-to-noise ratio (SNR).

Directionality

Directionality indicates how many decibels (dB) are lost as a bat moves farther away from the most sensitive part of a microphone. EMT 2 PRO and EMT 2 detect bats broadly in front of you while minimizing any echoes bouncing off your body.

Key Features:

• High-Fidelity Recordings: Low-noise microphone captures even weak or distant echolocation, reducing false positives.
• Real-Time Listening: Patented RTE technology preserves the tone and rhythm of ultrasonic calls.
• Species Suggestions: Automatic identification of the two most likely species, based on advanced acoustic analysis (region dependent).
• Free App: Available for iOS and Android. Includes live spectrogram, maps, recording, and customizable features.
• Mapping and Sharing: View recorded paths and instantly share files.

Eijkelkamp Analysis System to Measure Soil Oxygen Content

$ 4,795.00 USD $ 5,110.00 USD

With the Soil oxygen content analysis system you carry out a soil gas analysis easily and quickly with the help of a needle probe and an oxygen content meter, without the need for drilling.

• Measure soil contamination without the need for complicated drilling.
• The meter allows you to measure up to 0% O2.
• Immediately shows the living conditions of the roots.

This robust system consists of a short soil probe and an oxygen content meter. The probe is pushed into the soil manually. Once at the right depth the probe is lifted slightly to open it. Subsequently the oxygen content meter is connected to the probe and with the aid of a bellows, soil gas is sucked through the meter and the O2 content is measured, which is an important growth parameter for trees and plants.

The probe has a small dead volume, so that a measurement can be taken accurately within a few minutes. The meter allows measurements up to 0% O2 content.

The oxygen content meter works with an electrochemical cell. This cell has a limited service life (about 1.5 years), but can be easily calibrated with air (21%) and with an oxygen-free gas (natural gas, nitrogen).

Note: Please note that the meter requires regular renewal of the O2 sensor.

Eijkelkamp Beeker Sediment Core Sampler

$ 6,921.00 USD

The Beeker type sediment sampler is rod-operated and has a closable cutting head and piston. This sampler is used for high accuracy sampling of very soft to medium hard sediment layers. A standard and extended set are available.

With the Beeker sampler, you can take undisturbed sediment samples in a fast and certain way from watery sediment to unconsolidated sand to a depth of 5 metres. Even in watery conditions, the sample will not be lost thanks to the closable cutting head. Using additional extension rods, sampling to greater depths is possible in certain cases. The Beeker sediment core sampler works almost the same way as a Multisampler / piston sampler, but with a lockable head with inflated membrane.

Key Feactures

• Takes samples fast and certain
• Sample can be emptied into clean stainless-steel bucket, or layer by layer in wide necked sample jar
• Soil profile description and classification
• Contaminant free stainless steel body
• Possible to hammer the sampler

Method

The samples are taken in a transparent tube which allows you to make a clear profile description. The sampler has long sampling tubes of 1 metre. The piston can be operated directly with a rod, so that the sample can be pushed out of the sampler on site into a sample bucket. The apparatus is pushed or hammered into the sludge. To avoid compaction of the layers, a piston is held at a stationary position relative to the sludge. The sample can then be emptied into a clean stainless-steel bucket, or layer by layer in wide necked sample jar. It is not necessary to assemble and disassemble the apparatus with every new sample. This set comes in an aluminium transport case.

Extended set

In addition to the standard set (04.23.SA), an extended set (04.23.SB) is also available for sampling and discharging core samples with a length of 1 metre or 1.5 metres, in bucket or jars and to transport and divide in subsamples with water pressure. This set is suitable for sampling of submerged soils to a depth of 5 metres from very aqueous sediments to unconsolidated sand.

Applications

• Soil profile description and classification
• Environmental soil research
• Undisturbed sampling
• Geohydrological research
• Sediment sampling

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.

• Removable and Wind-Resistant Bait Tray. Includes a 20 cm diameter tray that secures firmly to withstand wind.
