Digital Thermometer 390

E-OPT CA 022


The T390 digital thermometer is a digital device with four input channels for type K and type J temperature sensors and two input channels type Pt100 temperature sensor. The T390 digital thermometer has an internal memory through a SD card (from 1 to 16 GB). Data is registered in the memory card (xls format) of the T390 digital thermometer so any additonal software is required for further analysis.

The optional software of the T390 digital thermometer, which comes included with a RS-232 cable, allows the user to store values so that this data can be transferred to a computer for further analysis. Time intervals can be programmed for using the digital thermometer as a data logger ensuring that all readings get stored over an extended period of time. The T390 digital thermometer can be used to measure online or as data logger. The display of the T390 digital thermometer simultaneously shows the four channels temperature (when they are connected to the corresponding sensors).

 The T390 digital thermometer can be used as a handheld device in situ or as a data logger for monitoring temperature fluctuations over a period of time. The T390 digital thermometer can be used in an almost unlimited capacity in maintenance, conservation, machine diagnostics and quality control. The T390 digital thermometer  can also be used for measuring in real time or as a data logger. Type-K, J and PT100 temperature sensors can be connected to the T390 digital thermometer.
