Spherical Quantum Sensor

LI-193SA

Measure light in the entire room

Because plants use light from all directions, it’s useful to measure reflectance from the surfaces in your greenhouse, grow rooms, and chambers.

Why measure light from all directions?

Originally designed as an underwater sensor, the LI-193SA Spherical Quantum Sensor also measures light in the air, providing insights on how to maximize the efficiency of your grow lights and reflective surfaces. Its compact size makes it easy to map light intensity and its impact on your grow in all areas of your space, including within canopies to map light reaching lower leaves. Use the LI-193SA with the LI-250A Light Meter and the 2222UWB-3 cable to capture PAR from a near 360° range.
