SM-600: Apogee Guardian Multi-Sensor Monitor

(1-4 week lead time)

The Apogee Guardian is an elegant device that provides accurate measurements of important indoor environmental parameters. It is a user-friendly datalogger with multiple integrated sensors to measure ePAR (SM-600), air temperature, humidity, vapor pressure deficit and dewpoint, CO₂ concentration, barometric pressure, and daily light integral* and photoperiod* (*only accessible via Bluetooth). Graphical summaries of these measurements can be downloaded to dataloggers via Modbus or smartphones via Bluetooth with the Apogee Connect app (iOS/Android). While the Guardian can take measurements as a stand-alone device mounted to a mast or hung by thin wires, it can also integrate into systems for greenhouses, grow rooms, and vertical farms via Modbus or Bluetooth.

Includes a 5-meter cable; longer options available if needed.

Mounting
There are two primary ways the Guardian can be deployed: hanging from thin wires or being mounted to a mast. Each package comes complete with wires for suspending the Guardian. Apogee also sells a mounting bracket for attaching the Guardian to poles or masts called the AM-270 (coming soon).

Typical Applications
Accurate environmental measurements in controlled environments, such as greenhouses and growth chambers, help aid in decision making and environment management. Monitoring PAR or ePAR intensities, daily light integral and photoperiod, CO₂ concentration, barometric pressure, and other parameters is critical for plant health, growth rate, photosynthesis levels, plant morphology, and crop steering. Required levels vary greatly by species and should be measured and controlled for optimum specimen health.

Calibration
To ensure accuracy, each embedded quantum sensor located in a Guardian is carefully calibrated in controlled conditions and traceable to NIST reference standards.

Spectral Response
The Guardian comes in two different spectral ranges: 389 to 692 nm PAR (SM-500) and 383 to 757 nm ePAR (SM-600). The spectral responses of SM-500 (blue) and SM-600 (green) can be seen in the graph below.

Warranty and Support

All Apogee products are backed by an industry-leading four year warranty and outstanding customer support.
