Product Overview

QTMC Series

QTI’s miniature NTC precision thermistors feature a small 0.038 inch maximum bead diameter providing an extremely fast thermal time response. The QTMC mini bead NTC thermistor is an extension of the QTI Interchangeable series for applications that require interchangeability in a smaller size. The small 0.038 inch bead diameter provides an extremely fast thermal time response. Standard 6 inch long #34 AWG insulated leads enable direct placement into probe housings or remote temperature sensing where space is limited. This thermistor is ideal for life science and/or medical applications.
