ITC PARwise (Seneye) - Light measuring

Understand your lighting

ITC Reefculture originated from the desire to create unique and functional tools for all aquarium owners. Tools and accessories to help us all keep our aquariums and inhabitants in better condition. Livestock welfare is at the heart of our business, whether it's helping produce tools for those who want to restock corals, shred them, or stop pests! PARwise is the latest tool that puts an end to the question of what setting my lamps should have, be it brightness, color (spectrum) or photoperiod. PARwise enables you to make the right decisions about your lighting settings and to share and discuss lighting in depth with the aquatics community, with accuracy – whether your organism is aquatic or not!

What is it?

PARwise is a unique light meter with the ability to measure spectrum. It can be used underwater and in the air. It gives you all the relevant lighting measurements needed to make informed decisions.

What does it measure?

PARwise measures 'PAR' (PPFD – Photosynthetic Photon Flux Density µMol/m2/s), Kelvin (Color Temperature), LUX, Spectrum, DLI (Daily Light Integral), Peak Wavelength, Hue (as colour)

How does it work?

PARwise uses the in-house created and designed optical engine nestled beneath a user-replaceable cosine corrector to 'read' the spectral content and amount of light incident on it. We then determine the results on board within PARwise and send them via USB to your device for display. Our web-based app automatically downloads to your device (pc, mac, android) the first time you use it, so you can use it completely offline. We're including a free USB-C adapter that fits Android smartphones, tablets, and modern computers that don't have a full-size USB port.

Note: Does not work with iOS or iPadOS yet, as Apple does not allow USB OTG on their mobile devices.

How to use?

Follow the instructions to get your PARwise up and running – simply place the sensor next to your photosynthetic organism, such as a coral or plant, and take a measurement. Use the on-screen pause button to capture the measurement in that position and compare your spectrum to a known spectral response curve or other light setting you want to copy or tune to.

Which languages are available?

The web app currently offers English, French, German, Dutch, Italian, Portuguese.
