Electronics International provides the budget-conscious pilot the option to monitor their Carburetor Temperature and Outside Air Temperature with the same precision found in the most advanced analyzers on the market, while not breaking the bank. The CA-1 provides pilots with One Channel of Carb Temp and One Channel of OAT readings in a stable, one-degree digital format. An “Ice Zone” Warning Light alerts the pilot when either temperature is between 10 Degrees to 39 Degrees (Fahrenheit). With a toggle switch, select which temperature you would like to monitor. The large, crisp LCD is viewable in direct sunlight, and is backlit, making it easy to monitor your Carb Temp and OAT.
