Replacement O-ring for HOBO Pro loggers - 85-ORING2

A data logger (or datalogger), commonly referred to as a 'HOBO', is an electronic instrument that records measurements (temperature, relative humidity, light intensity, on/off, open/closed, voltage, pressure and events) over time. Typically, data loggers are small, battery-powered devices that are equipped with a microprocessor, data storage and sensor. Most data loggers utilize turn-key data logger software on a personal computer to initiate the logger and view the collected data.
