This promotional package includes a SQ-100X-SS2 Original X Quantum sensor (with a 2 meter cable), a microCache Bluetooth micro-logger, an AA-090 protective Neoprene Case, an extra 2545 microCache battery, and an AM-020 Apogee PVC Sensor Platform. 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-100X 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 free ApogeeConnect app. The app allows you to make real-time measurements, set custom datalogging intervals, monitor and graph daily lights integrals, assure photoperiods, download datasets, and more.
