Abstract

A soil tester is disclosed, and comprises a housing and a sampling apparatus. The housing includes an interior sampling chamber configured to receive a sample container. The sampling apparatus comprises a photodetector and a light source. The photodetector is mounted along a portion of the interior sampling chamber and has a variable resistance determined by a property of incident light. The light source is mounted to the interior sampling chamber in a transmissive orientation relative to the photodetector so that a beam of light can be transmitted from the light source to the photodetector through the interior sampling chamber. A display on the housing is responsive to the photodetector.
