The 8200-104 Opaque Long-Term Chamber builds on the trusted and patented technology from the previous generation. This line of long-term chambers withstands the elements with improvements to the design. The 8200-104 accepts industry standard SDI-12 connections to include the sensors and measurements you want at each chamber.
A motorized chamber finished in durable and reflective white enamel rotates away from your soil collar. This allows the soil in the collar to see natural environmental conditions when a measurement is not taking place. The chamber may be left unattended for extended periods of time to make automated measurements, with low power draw (7.5W maximum when opening or closing).
