The Madgetech LCS140 Lethality Compliance System is a wet-bulb dry-bulb unit designed to calculate humidity in high temperature locations such as smokehouses, ovens and drying kilns. The LCS140 kit includes a dual-probe temperature data logger with two rigid probes. The dry-bulb probe is 2 inches for measuring ambient temperature and the web-bulb probe is 5 inches, allowing it to be covered with the included sock. Capable of withstanding temperatures from -40°F to 284°F (-40°C to 140°C), the dual probe LCS140 takes wet-bulb and dry-bulb readings simultaneously to determine the amount of humidity present.

This high temperature humidity data logger is compatible with the latest MadgeTech 4 Software making starting, stopping, and downloading simple and easy. Graphical, tabular, and summary data is provided for analysis and can be viewed as customizable engineering units. When coupled with the MadgeTech 4 Software, the LCS140 eliminates the need for complex calculations with a psychrometer.
