The extended 2 meter cable of the SQ-500-SS2 allows the microCache to be positioned safely away from the water while taking readings of your reef tank. The SQ-500 sensor is a trusted industry standard for making accurate measurements. The new AT-100 microCache (µCache) micro-logger is a rugged, standalone, battery-powered device that can collect over 400,000 data points and connects the sensor to your iOS or Android device via Bluetooth using the ApogeeConnect app. Together, the sensor and bluetooth datalogger are a powerful tool for monitoring photosynthetically active radiation (PAR) with research-grade accuracy. This takes the guesswork out of setting up your lighting, and ensures that you are providing a proper range of light intensity for your corals to support healthy growth and vibrant colors.
Sensor designed for underwater use
Full Spectrum
Works with all lighting types
Improved spectral response
2-meter shielded cable
ApogeeConnect App for iOS & Android
The app allows you to make real-time measurements, set custom datalogging intervals, measure photoperiods, and more. With the microCache, the sensor can transmit real-time readings, graphs, and tables of photosynthetic photon flux density (PPFD), daily light integral (DLI), and photo period. It also includes adjustable darkness offsets, an optional immersion correction factor, and custom sample averaging settings.
