Buyer's Guide: Temperature Monitoring

January 2022 - Vol.11 No. 1 - Page #16
Category: Temperature Monitoring

With health care’s increasing reliance on wireless systems, the day is coming when all laboratory refrigeration equipment will need to be continuously and positively monitored, and deviations automatically tracked. As the technology matures and accreditation bodies revisit their existing guidelines and regulations, clinical laboratories have come to rely more on continuous, positive monitoring for all temperature sensitive materials.

Ultimately, positive temperature monitoring helps ensure the highest quality patient care through accurate results and shortened turnaround times by reducing the need to prepare additional reagents and perform unnecessary QC and calibrations. While there are distinct costs involved in employing dedicated, medical-grade refrigeration equipment, along with sophisticated and robust monitoring systems, to seamlessly maintain tight temperature ranges, these costs are counter balanced by the benefits of persistent, best-quality conditions for reagents, controls and calibrators, patient samples, and testing equipment, as well as the ultimate benefits to the patients.

The following is a sampling of key temperature monitoring systems now available. Please visit for a full listing of laboratory vendors and products.
