With dimensions of 62 x 47 x 19mm (2.4 x 1.8 x 0.75in) TR-5i series loggers may be small, but they are built to last. In addition to the LCD on the front panel, the built-in alarm LED makes warnings easily visible. TR-55i-Pt is designed for use with Pt sensors and measures in the wide range of temperature from -199℃ to 600℃ with superior accuracy. Note: We carry Pt sensors as optional parts.
