KEITHLEY System, Scanning and Thermometer Model: 740

Product Information

The KEITHLEY Model 740 is a system scanning thermometer capable of making temperature measurements using seven different thermocouple types or millivolt measurements, covering a wide range from -200°C to +1820°C. It features automatic scanning and data storage, with a scanning rate of 20 channels per second, and the ability to expand to 81 channels. The device offers open thermocouple detection, IEE Smart Print mode, and digital calibration, making it a versatile and reliable tool for various temperature measurement applications. This system is expandable to 81 channels, allowing for extensive data collection and analysis. The Model 740 is designed to operate in an environment with temperatures ranging from 0-50°C with relative humidity below 80%. It is a powerful, dependable tool for temperature measurement and data collection in laboratory settings.
