Structured to assist in consistent experimental procedures, the Climate Measuring Device Testo 440 Laboratory Set is designed for versatile use across various climate-related parameters. This hand-held measuring device supports measurements in degrees Celsius, percentage relative humidity, meters per second wind speed, hectopascals pressure, parts per million carbon monoxide and carbon dioxide levels, and lux illumination. Its expandability allows integration with an extensive collection of digital probes, smart probes, or multiple temperature probes. The device stores menus for swift, dependable, and efficient execution of measuring tasks, featuring a graphical display that concurrently shows three measured values. It comes equipped with an internal memory capable of storing up to 7500 measurement logs, which can be accessed via a USB interface and exported as a CSV file. Enhanced user convenience is achieved through cordless measuring with Bluetooth
