Description
The Keithley Model 740 System Scanning Thermometer offers precise temperature and millivolt measurements using seven distinct thermocouple types (J, K, T, E, R, S, B). With a scanning capability of up to 81 channels, this unit facilitates automatic data storage and features digital calibration, a 24-hour clock, and an open thermocouple detection. Designed for use in high-demand laboratory environments, it can measure temperatures from -200C to +1820C. In very good condition, the system shows minor cosmetic wear from previous usage and includes a power cord. It has passed functional tests confidently, ensuring operational readiness for advanced laboratory applications.
