PARwise USB Light Meter – ITC Reefculture

Achieve Accurate Light Settings with the PARwise Aquarium Light Meter

Smart Submersible Quantum (PAR) Sensor

PARwise helps answer the question of how to set your aquarium lights, whether it involves brightness, color (spectrum), or photoperiod. PARwise empowers reef keepers to make informed decisions about their lighting settings. Achieving optimal growth rates requires three key factors: the right wavelengths, the correct light intensity, and precise timing. Light varies with depth and water clarity, as do the needs of plants and animals. Unfortunately, the human eye isn’t very good at judging light levels and colors! PARwise offers a user-friendly light meter that provides a clear understanding of your lighting and how to fine-tune it for optimal results, proudly designed and manufactured in the United Kingdom.

What is PARwise?

PARwise is a unique light meter with the ability to measure the spectrum. It can be used underwater and has a special mode for use in the air. Two light meters in one! It provides you with all the relevant lighting measurements necessary to make informed decisions about your light settings and photoperiod.

What PARwise Measures:

• PARwise measures ‘PAR’ (PPFD – Photosynthetic Photon Flux Density µMol/m2/S)
• Kelvin (Color temperature)
• LUX
• Spectrum
• DLI (Daily Light Integral)
• Peak Wavelength
• Hue Color

How It Works.

PARwise uses a proprietary, in-house made, and designed optical engine nestled underneath a user-replaceable cosine corrector to evenly ‘read’ the spectral content and quantity of light that hits it. PARwise sends the data over USB to the connected device to display the results. The web-based app automatically downloads to the device (Windows, macOS, Android) the first time it is used. Included in the box is a free USB-C adaptor to fit into Android smartphones, tablets, or computers (if needed).

Important Note: PARwise requires an Android device or a computer to operate. It is currently not compatible with iOS or iPadOS because Apple devices do not support USB OTG.

How To Use:

Follow the user instructions to get thePARwisedevice up and running – then place the sensor next to a photosynthetic organism such as a coral or plant, and then take a reading. Use the on-screen ‘pause’ button to capture the reading in that position and reference the spectrum against a known spectral response curve or another desired light setting.
