Digital Temperature Indicators
Portable, Panel Mounting, Multipoint and Infrared
Models: PE 221, PE 221 P, PE 221-6
Temperature Indicators for Thermocouples & RTDs
Four types of indicator for industrial temperature measurement: portable, panel mounting, multipoint and infrared (contactless). The portable and panel models work with thermocouples and RTDs, with automatic cold junction compensation.
