MediSafe Logger Options

Options for Medisafe fridge owners

For older Medisafe Plus fridges

Up until a few years ago, the manufacturers of Medisafe Plus vaccine fridges included LogTag temperature loggers with some of their models. They built the LogTag probe cable into the fridge so that the LogTag sensor was located right next to the sensor for the fridge’s temperature display. 

If you have one of those fridges, these are your options for replacement loggers…

Latency explained

What is latency?

Latency, when it comes to temperature logging, refers to the delay between a change in temperature and when that change is detected and recorded by the logger. This delay can be due to the sensor’s design, the materials it’s placed in, or the logging interval. While it might sound like a disadvantage, latency can actually serve a useful purpose in certain environments—particularly where short-term temperature spikes are common but not harmful.

For example, in a busy commercial fridge, the temperature may briefly rise every time the door is opened. A logger with high latency won’t immediately react to these short fluctuations, helping to avoid unnecessary alarms or false data indicating a problem when there isn’t one. In these cases, a slight delay in response acts like a filter, focusing attention on real issues—such as prolonged exposure to unsafe temperatures—while ignoring the everyday ups and downs that don’t affect product quality or safety.

Differrnt connections

Connecting your logger

Depending on the type of logger you have, connecting your logger to your PC means either:

  • inserting into the Reader,
  • plugging it into a USB port, or
  • connecting it via a USB cable.

What's so good about USB?

First Generation LogTags use a separate Reader (sometimes called a dock) for configuration and for downloading recorded data. 

The Second Generation loggers only require a USB port or cable. Apart from saving the cost of the Reader, this makes them much better suited for shipping, because the recipient doesn’t need a LogTag Reader to download a report about the shipment’s journey.
