Model: TK


Fischer TK is long distance expansion thermometer and serves as indicator, monitor and controller. It is used in all industries where temperature need to be monitored.

The instrument’s temperature measuring unit is filled with nitrogen. Temperature changes at the end of the probe stem causes pressure changes in the filled system. An integrated coil spring converts this pressure change to a tension which intensified by a motion work and transferred to indicator dial, having 270° scale.
