Guth Laboratories 34C is an alcohol breath simulator, an instrument used to provide a precise calibration standard for testing and calibrating alcohol breath analyzers. It works by maintaining a water-alcohol solution at a precise temperature of
34∘C34 raised to the composed with power cap C
 (
±0.05∘Cplus or minus 0.05 raised to the composed with power cap C
) to accurately simulate human breath for testing.

  • Function: It simulates human breath by heating a water-alcohol solution to a stable
    34∘C34 raised to the composed with power cap C


  • Calibration: It is used to calibrate and test alcohol breath analyzers, ensuring they provide accurate readings.

  • Technology: It is an electronically temperature-controlled instrument with electronic temperature controls, often with dual temperature probes for precise control.

  • Application: It can be used with a pump to test handheld or evidential breathalyzers, simulating a live subject test more accurately than dry gas canisters
