We are pleased to announce the introduction of a new measuring device to our product portfolio – the Hydrogeological Whistle (DepthWhistle). This practical and reliable tool is designed for quick and accurate determination of water levels in piezometers, wells, and other monitoring boreholes.
DepthWhistle is a compact measuring device used in hydrogeology, environmental geology, and fieldwork related to groundwater monitoring. Its operation is based on a simple yet effective acoustic signaling mechanism – when the probe comes into contact with the water surface, a characteristic sound signal is generated, allowing the user to precisely determine the water level.
Thanks to its design, the device is easy to use and well suited for everyday field measurements. The hydrogeological whistle enables quick measurements without the need for complex electronic systems, making it especially useful during monitoring work, environmental studies, and groundwater level inspections.
Key advantages of the device
- fast and simple water level measurement
- clear acoustic signal when the probe contacts water
- lightweight and durable construction suitable for fieldwork
- ideal tool for hydrogeologists, geologists, and environmental monitoring companies
Introducing DepthWhistle to our offer is another step in expanding our portfolio of tools designed for professional hydrogeological measurements and field operations.
