The HATO ONE is an all-in-one light meter. A must-have for every poultry specialist who is aiming to improve animal welfare and performances by means of lighting. This product is able to measure all key aspects of light that matter for poultry: • Light intensity • Critical Colour Temperature • Light spectrum • Colour Rendering Index • Light flicker After measurement, the HATO ONE enables you to compare specific measurement results with poultry needs, human needs or other lamps on the spot to directly allocate points of improvement. All measurement data can be exported to a PC for further analysis as well. The results after measurement can immediately be seen at the HATO ONE App. Furthermore, the HATO ONE APP makes it possible to measure from a distance, so you don’t have to keep the meter in your hands all the time. Improve performances, start measuring! More information? www.hato.one
OSpectrometer
This app uses your device's camera and screen to perform basic optical spectroscopy. Analyze the visible light spectrum of objects, map light wavelengths to RGB values, and save or share your findings. It functions offline without external hardware.
- Visible light spectrum analysis
- RGB color value mapping
- Wavelength selection and scanning
- Front camera reflection sensing
- Save and share results
- Offline functionality

Optical spectroscopy in the visible light spectrum is a commonly used tool in different fields such as health, manufacturing, art, and forensic research. OSpectrometer implements basic spectrometer functions using the built-in camera and screen without requiring external devices or programs. - Visible light spectrum is transformed and mapped to a function that generates RGB (Red Green Blue) color values - A specific light wavelength can be selected and used to illuminate a desired target (i.e., close to the screen) - The whole spectrum or a specific part of the spectrum can be selected and scanned - Front camera is used to sense the reflection from the target object - Consistent and repeatable reflection/absorption amplitude with respect to the color spectrum - The result can be saved and shared - Works offline, no need to connect to any network or internet Privacy-policy: https://software.nanorescenter.com/osprectrometer-privacy-policy Terms of use: https://www.apple.com/legal/internet-services/itunes/dev/stdeula/
