A versatile Doppler velocity log (DVL) that balances compact design with high precision and high functionality.

To meet the growing global demand for measurement, we have expanded DVL's product lineup. And now, the long-awaited navigation package, which incorporates DVL and AHRS, has been newly launched in a palm-sized form, making it one of the smallest in the industry! It is adopted and mounted on various platforms, from small/micro-sized to work-class vehicles. In recent years, it has also been successfully used in large ASVs, UUVs, underwater gliders (specialized components), and even in ocean racing yachts (UK). Introducing the Nucleus1000!! An ultra-compact DVL navigation package equipped with DVL functionality and AHRS Measurement height: 0.05m to 50m, pressure resistance: 300m DVL1000 Measurement height: 0.2m to 75m, pressure resistance (2 models): 300m/4000m DVL500 (Compact) Measurement height: 0.3m to 175m, pressure resistance (2 models): 300m/4000m DVL500 Measurement height: 0.3m to 200m, pressure resistance (2 models): 300m/6000m DVL333 Coming soon Measurement height: 0.3m to approximately 400m, pressure resistance (2 models): 300m/6000m

What if waves and currents could be measured simultaneously at an offshore wind power site? Do you have concerns like this?

The Signature series is an ultrasonic current meter (ADCP) that can simultaneously perform direct measurements of sea surface elevation, measure circular motion current velocity below the sea surface, and obtain current velocity profiles. Using time series analysis and spectral calculations on the acquired data, it is possible to derive various wave parameters, including wave height and wave direction. For water depths exceeding the measurable range for wave measurement, the device can be mounted on a mid-water float for measurement. (*Nortek patented technology) The maximum water depth for wave observation is 150m, making it suitable for surveys at floating offshore wind power sites exceeding 50m in depth. 【Features】 - Direct measurement of sea surface elevation using ultrasonic technology with vertically arranged transducers - Continuous and simultaneous measurement of waves (sea surface elevation, circular motion current velocity) and current velocity profiles (multi-layer current velocity) (Nortek patented technology) - The measurement position of circular motion current velocity can be changed during post-processing (Signature1000/500) *For more details, please download the PDF or contact us.

A new ADCP equipped with a scientific fish finder sensor (frequency 70~120 kHz)! It can measure both flow and biomass with a single device.

The Signature100 is a completely new ADCP equipped with both a flow direction and velocity profiler (with a measurement range of 400m) and a scientific fish finder sensor (echo sounder). For example, when focusing on the relationship between the behavior of fish and microorganisms (such as krill) in the ecosystem and ocean currents, it was previously necessary to measure acoustic reflections (echograms) and flow direction and velocity data with separate devices. The Signature100 allows for the acquisition of both types of data with just one device. Specifications of the scientific fish finder sensor: Beam width: 15° (70 kHz), 8.7° (120 kHz) Monochromatic pulse: 70kHz, 90kHz, 120kHz Frequency chirping: center frequency 100kHz (BW50%, 70kHz–120kHz) Vertical data spatial resolution: 0.375–4m (1800 data points) Pulse length: 0.5–6ms Resolution: 0.01dB Dynamic range: 130dB

A lightweight, compact, and simple-shaped ultrasonic flow direction and velocity profiler. It also features pressure wave measurement (PUV) capabilities, catering to various measurement applications.

The Aquadopp Profiler is a highly versatile ultrasonic Doppler current profiler (ADCP). There are four types in the lineup depending on the measurement range (distance). It is the ideal ADCP for those who want to simply conduct multi-layer current and velocity observations. In particular, it allows for wave measurements using a pressure gauge to be performed between current and velocity measurements, making it a series with high cost performance. The model equipped with the Z-Cell function can emit sound waves horizontally from the sensor head, allowing for the measurement of flow around the instrument. This feature enables the measurement of flow very close to the instrument, which was difficult with conventional ADCPs. The measurement range is from less than 1 m to over 85 m. The measurement range is determined by the acoustic frequency of each model. (Model name: Maximum measurement range) - Aquadopp Profiler 2MHz: 20m - Aquadopp Profiler 1MHz: 25m (including Z-Cell) - Aquadopp Profiler 600kHz: 40m (including Z-Cell) - Aquadopp Profiler 400kHz: 90m

A super small current velocity profiler (ADCP) for shallow waters equipped with numerous new features!

We have streamlined the complex mechanisms involved in handling flow velocity sensors and revamped the design and functionality to enable measurements with as few steps as possible. For the first time at Nortek, data quality verification and processing will be performed in the cloud (eliminating the need for dedicated analysis software). Japanese language support is available. [Easy Operation] Automatically sets three water depths and continues measurements while tracking water level changes. Users do not need to specify the measurement depths. [No Cables Required] Non-contact communication (for Eco and disconnection device settings) *Uses the built-in Bluetooth communication function of a smartphone or PC. [No Battery Replacement Needed] Uses a built-in rechargeable battery with non-contact charging. [Simple Setup] Settings can be configured via a web page on the internet or a smartphone app (iPhone and Android compatible apps are available: Nortek Eco; the web page can be accessed via "Related Links"). [Features, etc.] - Low water depth compatibility: Measurements can be taken from 30 cm above the device. - Number of measurement points (water depth, layers): 3 - Equipped with GNSS - Multi-color LED for operation confirmation *Installation is only upward. *Output data will be the horizontal flow velocity (east, west, south, north) at three water depths, but the measurements are three-dimensional flow velocities.

Japan is one of the top 10 countries in the world with frequent earthquakes. The 2020 White Paper on Land, Infrastructure, Transport and Tourism has also reported an increase in the probability of major earthquakes occurring. Regarding the Nankai Trough earthquake, the probability of an earthquake with a magnitude of 8 to 9 occurring within the next 30 years is estimated to be 70 to 80%. At Hotron, we recommend the introduction of seismic devices for earthquake countermeasures in buildings and equipment. The seismic device 'HK-2' is a product that automatically performs various controls that have been pre-set when it detects strong shaking equivalent to a seismic intensity of 5 lower or higher. For example, it can automatically execute actions such as: "Open automatic doors and gates to secure evacuation routes and access for emergency vehicles" "Transmit signals to the control room and stop facility equipment" "Unlock the keys to locked lockers" "Automatically play voice guidance" For more details, please download the materials or contact us.
