Overview of PQ-500 Package microCache and Full-spectrum Quantum with 30 cm cable

User's Manual

This promotional package includes a SQ-500-SS full spectrum quantum sensor with 30cm cable, a micro Cache Bluetooth micro recorder, an AA-090 neoprene protective sleeve, an additional 2545 micro Cache battery and an AM-020 Apogee PVC sensor platform. After pairing, these devices are powerful tools for monitoring photosynthetically active radiation.

The new AT-100 microCache (µ Cache) micro recorder is a rugged, independent battery powered device that can collect more than 400000 data points, and use our free Apogee Connect application to connect your sensor to your iOS or Android device through Bluetooth. The application allows you to perform real-time measurements, set custom data recording intervals, monitor daylight integration and draw charts, ensure light cycles, download data sets, and more.
