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. The TR-55i-V can measure and record analog signals output from instrumentation such as sensors in a range of 0-22 V.
