This promotional package includes both an SQ-500-SS2 Full-spectrum Quantum sensor (with a 2 meter cable) and microCache Bluetooth micro-logger at a special introductory price. The extended 2 meter cable of the SS2 model allows the microCache to be positioned further from the sensor, such as out of the water when used with coral reef tanks or for other applications. When paired, these two devices are a powerful tool for monitoring photosynthetically active radiation with research-grade accuracy for optimal specimen growth. The SQ-500 sensor is a trusted industry standard for making accurate PPFD 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 your sensor to your iOS or Android device via Bluetooth using our ApogeeConnect app. The app allows you to make real-time measurements, set custom datalogging intervals, monitor and graph daily lights integrals, measure photoperiods, download datasets, and more.
