The CEA 700 is a continuous, infrared carbon dioxide analyzer that also measures and displays temperature levels in either °F or °C. Each handheld, compact unit is equipped with a large digital display, ac adapter, flip-out stand, and operation manual. Standard alkaline batteries last up to 80 hours for portable use, says the company. The units are said to be low cost, durable, and easy to use and maintain. Adjustments for automatic calibration and altitude changes plus other features are also included, the company says.
