Temperature Thermometer
Multi-channel Thermometers with Data Loggers ( TCD-72A / TCD-74A / BT-747D )

Multi-channel Thermometers with Data Loggers (TCD-74A / BT-747D)

Description
TCD-74A / BT-747D are the multi-channel thermometers / dataloggers for monitoring and documentation the fluctuations of thermocouple temperature in the fields of Production Processes, Laboratories, Engineering and After Service/Maintenance.

The real time data-logger accepts 4 thermocouple channels with Type K, J, T, E, R, S or N thermocouples. Store log data up to 10000 sets of readings real time for each channel with a perpetual calendar real time function. The unique CALL-FIT function allows you to read & search the desired log data from memory by 50 pages per second speed. All the data collected by the data-logger during long-term monitoring over periods can be sent to computers via RS-232C (BT-747D) or USB (TCD-74A) interface for further analysis using software based on Windows®.
