J,E,K Type THERMOCOUPLES FOR GENERAL USE
DATA SHEET
FTA,B,D
These thermocouples are convenient for measuring
a wide range of temperature in general plants, and are
availble in J, E and K type.
They are insulated with a porcelain tube, and then
housed in a metal protecting tube for heat-, pressure-and
corrosion-proofing.
