    KEITHLEY System, Scanning and Thermometer Model: 740

    **This unit has been tested to specifications. Has slight cosmetic blemishes from normal use. See photos for further details.

    The Model 740 is a system scanning thermometer that can make temperature measurements using seven different thermocouple types ( J, K, T, E, R, S, B) or millivolt measurements. With the use of the various thermocouple types, temperature measurements in the range of -200 C to +1820 C can be made. A single internal channel is standard equipment in the Model 740. The installation of a Model 7057A scanner card into the Model 740 expands the available measurements channels to nine. The measurement system is expandable to 81 channels with the addition of four Models 705s, or one Model 706 with eight scanner cards installed.
