AM1660/1640/1620 Precision Industrial PRTs

OVERVIEW

The AM1660/1640/1620 series


Precision Industrial PRTs (IPRTs) are
rugged probes with excellent
accuracy and stability. These IPRTs
cover a wide range of temperatures
from -200°C to 670°C, with an
FEATURES amazing accuracy of ±0.035°C and a
Temperature range: -200°C to 670°C short term stability of ±0.01°C.
