There are two models in the 6622T Thermometry Bridge Series providing increasing levels of accurary and are wellsuited for temperature calibration and research.


The use of a DCC bridge in thermometry is beneficial as it hasinherently better noise immunity to external electromagnetic noise and mechanical disturbance.


One of the key features of Guildline's Thermometry bridges is that they are verified at the lower currents found in thermometry.


The 6622T Provides the Widest Range of Temperature Measurement of Any Commercially Available Temperature Bridge Today!
