The AM-140 mounting adapter is a high-quality 3D printed part designed to accommodate S2 series NDVI and PRI sensors, which consist of upward-facing (models S2-111, S2-422, S2-121, and S2-421) and downward-facing sensors (models S2-112, S2-412, S2-122, and S2-422). The AM-140 fixture comes with a 12" mounting rod and has an integrated bubble level to make leveling simple and accurate for proper sensor installation. The 12" mounting rod interfaces with the AM-500 Net Radiometer mounting bracket. This mounting adapter purchase does not include any sensors.
