Echo Meter Touch 2 Bat Detector

Turn your smartphone or tablet into a professional bat detector, available in Standard and PRO versions for real-time monitoring and high-fidelity recordings.

Echo Meter Touch 2 PRO Bat Detector Tutorial Videos

The Echo Meter Touch 2 (Standard and PRO) transforms your smartphone or tablet into a professional bat detection tool. Designed for researchers, environmental consultants, and wildlife enthusiasts, it provides high-fidelity recordings with noise reduction and enhanced bat call capture. Compatible with Android (USB-C or Micro-USB) and iOS devices, it works in the field without internet connection. Includes real-time listening modes, interactive spectrograms, geolocation, and automatic species suggestions via Bat Auto-ID technology.

Bat echolocation calls are ultrasonic and generally inaudible to humans. The Echo Meter Touch 2 combines a specialized microphone with advanced circuitry and software to convert these ultrasonic calls into audible sounds. Calls are displayed in a scientific-level interactive spectrogram. Users can pause audio, zoom in on recordings, and listen in one of three professional modes: Real-Time Expansion (RTE), heterodyne, and post-recording time expansion.

Both Standard and PRO models allow real-time bat monitoring, probable species identification, visualization of echolocation, recording location tracking on maps, and easy sharing of findings. The PRO version adds higher sensitivity, electronic noise reduction, and advanced recording options, while the Standard version delivers reliable professional performance for bat research and observation.

Signal-to-Noise Ratio (SNR)

The SNR measures the volume of bats relative to background and electronic noise in a recording. A bat detector with high SNR is preferable, as it can capture faint or distant 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 record high-frequency bats (above 60 kHz).

Sensitivity and Noise

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

Directionality

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

Key Features

Listen to and record bat vocalizations in real time.
Automatic identification of the most probable bat species via the free Echo Meter Touch app for iOS and Android.
Visualize echolocation calls in real time with an interactive spectrogram.
Track recording locations and routes on zoomable maps.

Sistema de análisis de Eijkelkamp para medir el contenido de oxígeno del suelo

$ 4,795.00 USD $ 5,110.00 USD

Con el sistema de análisis del contenido de oxígeno en el suelo, realiza un análisis de gases del suelo de forma fácil y rápida con la ayuda de una sonda de aguja y un medidor de contenido de oxígeno, sin necesidad de perforar.

Mida la contaminación del suelo sin necesidad de perforaciones complicadas.
El medidor le permite medir hasta 0% O2.
Inmediatamente muestra las condiciones de vida de las raíces.

Este robusto sistema consta de una sonda de suelo corta y un medidor de contenido de oxígeno. La sonda se introduce en el suelo manualmente. Una vez en la profundidad adecuada, la sonda se levanta ligeramente para abrirla. Posteriormente, el medidor de contenido de oxígeno se conecta a la sonda y, con la ayuda de un fuelle, se aspira el gas del suelo a través del medidor y se mide el contenido de O2, que es un parámetro de crecimiento importante para árboles y plantas.

La sonda tiene un volumen muerto pequeño, por lo que se puede realizar una medición precisa en unos pocos minutos. El medidor permite mediciones de hasta 0% de contenido de O2.

El medidor de contenido de oxígeno funciona con una celda electroquímica. Esta celda tiene una vida útil limitada (alrededor de 1,5 años), pero se puede calibrar fácilmente con aire (21 %) y con un gas libre de oxígeno (gas natural, nitrógeno).

Nota: tenga en cuenta que el medidor requiere una renovación periódica del sensor de O2.

Eijkelkamp Beeker Sediment Core Sampler

Request Quote

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

EMS Band Dendrometer DRS26 for Large Trees from 30 cm

Precisely Monitors Radial Tree Growth With Fast Detup for Research and Forestry Applications

The EMS DRS26 band dendrometer is a digital sensor that accurately measures the circumferential increment of large tree trunks with micrometer precision, without affecting their natural growth. Its non-invasive design and high resolution make it ideal for studies of plant growth, water stress, and environmental response.

Features

Precise digital measurement with sub-micrometer resolution.
Non-invasive installation that does not affect tree growth.
No upper limit on trunk diameter.
SDI-12 digital output for easy integration with monitoring systems.
Low maintenance and energy requirements.
64 mm measurement range for circumferential growth.
Provides data on growth, water stress, and trunk freezing.
Compatibility with different tree diameters by changing the base plate.

Non-Invasive Tape Fixing System

The EMS DRS26 dendrometer uses a tape fixing system (D RL 26 C) that does not damage the tree or affect its natural growth. This innovative method:

No effect on tree growth
Integrated value for the entire radial profile at the measured height
Almost identical thermal expansion of wood and stainless steel

Complex Dendrometric Data

Dendrometer data

Efficient tool for field measurement
Includes information on growth, water stress, and trunk freezing
Low maintenance and energy requirements compared to sophisticated systems like sap flow
Together with soil water potential measurement, it provides a realistic picture of water stress and tree response

SDI-12 Data Output Asynchronous serial communications protocol for intelligent microprocessor-based sensors. The sensor typically takes a measurement, performs calculations based on the raw sensor reading, and outputs the measured data in engineering units. It allows the connection of a set of sensors in series on a cable line. For more information, visit the SDI-12 website. Measure trees with different diameters by simply changing the base plate.
