I was recently asked to make a daily min/max graph. I questioned the wisdom of this and showed how it was built on old compromises that don’t need to exist anymore. It’s time to move on.
Twenty years ago we had domestic fridges with min/max thermometers and had to daily downloads to ensure they weren’t freezing. Now we have vaccine fridges and temperature loggers, and we are still downloading daily. Why?
No cause for alarm Modern vaccine refrigerators are fantastic devices and take much of the worry out of storing vaccines safely. When they’re working properly, that is. We recently had a customer who was getting some slightly strange readings from her temperature logger, despite not getting an alert from her refrigerator. The graph of readings […]
RPA is now asking hundreds of mothers with new born babies to contact them because a vaccine fridge may have been failing.This strikes me as an amazing problem for a major hospital. For more information see the full article from the SMH Low cost temperature loggers have now been available since I started this business […]
Getting the mix right with reporting It is common practice to print a report of results for future reference. Traditionally there were two extremes – a detailed report that could go on for 30 pages, or a daily/min max report that summarised it all to 30 lines. A better option for many users is the […]
This is the first blog in a series that will discuss various aspects of temperature monitoring, with a focus on temperature loggers. Much of what is discussed can also be applied to thermometers. One of these blogs will actually discuss the differences between thermometers and temperature loggers. Money, reputation and lives There are some things […]
The Pharmacy Guild of Australia have donated temperature loggers to an “exceptional cause” Over the years we have been approached by a number of charities for discounted or free products. Unfortunately about 30% of our customers are linked with charitable organisations, or are products that are aimed at “good causes”. But every now and then […]
Once again, this problem is really obvious in hindsight but is easily done. The way it comes about is quite simple and this is fairly common… Someone buys a logger and uses it They leave the company The new person has no idea that the logger exists, let alone that they need to do something […]
As mentioned in the last post, this one is obvious, but more often than not, it is really obvious in hindsight. The way it comes about is quite simple and this is fairly common… Someone buys a vaccine fridge and is all happy and excited about their new purchase. They turn it on, let it […]
After common temperature logger mistake 2 of sampling too quickly, mistake number 3 is the exact opposite. There are some users who sample as fast as possible. This is typically once a minute for Thermocron loggers and possibly even faster for Logtags. The likely cause For the sampling too slowly issue, the cause was historical however with sampling […]
After common temperature logger mistake 1 of not being turned on, mistake number 2 is reported to us less, but more common. There are many users who set their sample rate to one sample every couple of hours. This is typically 4 hours for the Thermocron and even slower for Logtags. The likely cause […]
There are two main causes for this. Getting a new unit and placing it straight in a fridge without starting it Stopping it to retrieve results, and not restarting it The problem is quite simple – the unit is off and has no idea what is happening. This problem tends to lead to some […]
We are often asked what is the best sample rate for vaccines. Or worse, we aren’t asked and we find out what some people are doing. The worst option Sampling once per day (or once every 4 hours depending on the logger’s capability) is the least effective approach. This is a hangover from the […]
We are often asked about temperature logger calibration versus certification. There is some confusion between the two and what is required. This should clarify many of the questions: What is Supplied: 1. Our temperature loggers are tested at the point of manufacture to make sure they meet the specifications. This is the Quality Control […]
It’s Friday, so a bit of light hearted content. Here are some entries you are not likely to find in the Office Dictionary: LECTURE: An art of transmitting Information from the notes of the lecturer to the notes of students without passing through the minds of either CONFERENCE: The confusion of one man multiplied by […]
This USB temperature logger review looks at the strengths and weaknesses of the standalone USB loggers. The fact that it has a built-in USB port means it doesn’t require any additional hardware to program or retrieve results. This makes it ideal for shipping type applications. It also reduces the overall price, especially when only one […]
