In one of the hottest environments in the world, keeping ice cream cool and frozen is a very difficult task. A leading manufacturer of ice cream in Dubai uses a network of Dickson data loggers to monitor this task. The goal is to monitor temperatures and deliver sweet frozen treats across the Middle East.

Constant monitoring is a necessity with outdoor temperatures routinely exceeding 90°F. The monitoring solution has to log past data to meet government regulations, but also allow Quality Assurance Officials the ability to view current conditions. This is necessary so action can be taken if environmental conditions change. It also allows staff to react and save inventory or fix a potential problem.

Short answer – NO!!!

In fact, to those of us in the industry who truly know what it takes to recalibrate instruments to objectively defined standards, a better question might be— Are you using the equivalent of a meat thermometer to validate conditions in your processing plant or laboratories?

Picture the situation you like to picture least…

A drug your company manufactures is suspected of causing a rash of untimely deaths. A recall is initiated, an FDA investigation is launched, and personal injury attorneys start readying their suits. Every aspect of your operation goes under the microscope, so to speak, and that's when you learn that your plant's 'rigorous' quality control protocols for compliance (FDA GMP and 21 CFR Part 11) were not that 'rigorous" after all…

An array of instruments is available for monitoring temperature and humidity in high and low-tolerance environments.

Monitoring temperature and/or humidity conditions is an essential ingredient of a wide range of quality assurance applications. There are many common methodological errors, however, in ways that this task is approached that either compromise quality standards or add unnecessary time and expense to the monitoring task. Insufficient calibration of temperature and humidity monitoring instruments is high on the list of problematic areas. Mismatching technology to the monitoring task at hand is another problematic area. This article will revisit technology trends in monitoring instrumentation, provide tips on calibration and discuss common methodological errors that quality managers should avoid.
