PARwise USB Light Meter - ITC Reefculture

PARwise by ITC Reefculture is a cutting-edge, dual-purpose aquarium light meter designed to deliver the most accurate light readings possible—both in air and underwater. Built to help reef keepers and aquascapers fine-tune their lighting, PARwise eliminates guesswork by providing comprehensive light data essential for coral and plant health.

⚠️ Requires Chrome browser for access to the web-based PARwise app (not compatible with iOS devices).

Key Benefits:

Measures PAR, Spectrum, Kelvin, LUX, DLI & More

Smart Submersible Quantum Sensor – Functions underwater and in air

Optimize Light Settings – Tailor light intensity, duration, and spectrum for ideal coral or plant growth

USB-C Compatibility – Includes free adapter for Android devices, tablets, and computers

Web-Based Interface – Works with Windows, macOS, and Android

What PARwise Measures:

PAR (PPFD – Photosynthetic Photon Flux Density in µMol/m²/s)

Kelvin (Color Temperature)

LUX

Full Light Spectrum (380–800 nm)

DLI (Daily Light Integral)

Peak Wavelength

Hue/Color

How It Works:

PARwise features a precision optical engine beneath a user-replaceable cosine corrector. It reads light quality and quantity, sending data via USB to your device, where results are displayed through the downloadable web app. Just place the sensor next to your corals or plants and pause the reading to capture accurate values.
