Formulated to support synthetic operations, the Climate Measuring Device Testo 440 Basic is designed to measure various climate-related parameters such as temperature, relative humidity, air velocity, pressure, carbon monoxide, carbon dioxide, and illuminance. This versatile instrument can be expanded with an extensive collection of digital probes, smart probes, or multiple temperature probes. Its user-friendly design features intuitive operation, clear menu structures, and a graphical display that simultaneously shows three measured values. It offers an internal memory capable of storing up to 7500 measurement logs, which can be accessed through a USB interface and exported as a CSV file. Enhanced convenience is achieved with cordless measuring using Bluetooth probbes within a maximum range of 20 meters. Compatible with NTC, Pt 100, and TE temperature sensors, this device boasts a wide temperature measuring
