The control unit The control unit is a robust hand-held instrument for measuring temperature, humidity, pressure, velocity, 2,, current and voltage. User friendly Our easily read graphics display allows simultaneous tracking of 6 parameters, simple menu driven operation and 4 user defined function buttons. Touch pen operation is available as an option. User defined probe sockets 4 additional, user defined probe sockets can be added to the control unit with each attachable logger. Giving you the proper number of probes for your application. Simultaneous measurement at several locations The simultaneous measurement of data at several locations is carried out by the slave loggers. Measured data is transmitted via the Testo data bus. The control unit is able to control the entire measuring system. Data output - every conceivable option The measured data may be printed on location with the integrated printer. The measured data may also be analysed, documented and stored on your PC. The readings are output as a current signal (4-20 ) through the analog output box for process control or output on an analog recorder.
