Monitoring and documenting the temperature of sensitive goods Having the ability to keep track of the temperature storage of sensitive goods is crucial in healthcare. Everything from incubators to medical refrigeration units must be kept within the strictest boundaries.

O’Neill said the testo system has ironed out previously inefficient processes at the company. The system can consistently log data - storing up to 40,000 measurement values - and is highly accurate. “Before testo, we had a series of individual local temperature monitoring systems on each applicable device and we had to go round and actually manually check and record that those devices were operating at the right temperature,” he said. “That manual checking, depending on the device, may have only been on a 24-hour basis. “[Using the testo Saveris system] means that all of our devices are being monitored in a universal, continuous manner. It’s exactly the same process no matter what the device is - if there is an alarm, we know exactly what device it is. Our response to the alarm can be simply recorded, which makes it easier to manage and track issues, if any. We also have the ability to monitor devices located in areas which may not be staffed 24
