How accurate are the temperate loggers?
We are often asked how accurate are the Temperature MicroLoggers. The manufacturer claims an accuracy of ±1°C with a recording resolution of either 1/2°C or 1/8°C depending on the model. Typically we see the vast majority of loggers with an accuracy of ±0.5°C or better. The temperature sensors of individual loggers are QCed at the factory with NIST-traceable equipment, but the loggers are not issued with calibration certificates. Some clients will put the loggers into a stirred ice bath to calibrate individual loggers and record an ‘offset value’ for each logger. An ice bath calibration will give you greater accuracy and higher confidence, and will provide the type of documentation required for eg EUREPGAP.
