Zahner TEMP/U Addon-card



TEMP-U enables the measurement of temperature by direct connection of two different thermocouples. Two additional electrochemical potential measurements can be done by connecting auxiliary electrodes to the medium level inputs.


Unless otherwise noticed, the TEMP-U is delivered pre-configured for two NiCrNi-(type K)-thermocouples, temperature range –70C to +250C and two voltage inputs in the range of ±4V. An optional automatic cold junction compensation can be activated by a switch at the top of the front plate. All channels are bandwidth limited by means of anti aliasing filters.
