We sell many different models, and while I wish I could just keep one in stock, I can’t. The reason is simple, the answer depends on what it is needed for.
Here are a number of key factors:
Required Temperature Range: Temperature data loggers have a key range that they were designed for. Most of the common loggers on the market are designed for -20° to about 40°C. We have units that will log all the way down to -80°C and others that will log all the way up to 140°C, but there is nothing that will do the entire range. More importantly, the extreme models are not designed for the mid-range, but are really good at the extremes.
Size: This is an odd one because we sell one of the smallest loggers on the market but at the same time will try to make it larger for customers. Some customers like something “substantial” to see or hold onto. Others love having something small and discrete.
Indicators and displays: Indicators such as LEDs, and displays showing the temperature are great for many customers. They give immediate feedback to the user that everything is OK or if there is a problem. For others, they use the temperature data logger as an audit tool and they don’t want other people to know that the logger has detected a problem. Or the temperature data logger is in a box and wil never be seen.
Battery life: The indicator/display comes at a cost, and that cost is battery life. There are units with replaceable batteries but they are typically in units that will chew through power within months or a year. We also sell temperature loggers that will last up to a decade with its built-in battery.
Sensor type: Most of our temperature data loggers have a built in temperature sensor. For some customers, however, they need an internal temperature to be made and so the option for an external temperature sensor is essential.
Cost: Gone are the days of a temperature data logger costing hundreds of dollars, but there is still a bit of variation from an entry level unit up to the top of the range.
There are some other factors involved, but these are probably the key differences. Which leads me to the two reasons for writing this blog:
1. If you ring up asking us for the best temperature logger then please let us ask you a couple of questions. That way we can recommend the best unit for you. That’s a question we can answer.
2. If you need any advice, please give us a call or email firstname.lastname@example.org. We will gladly discuss your application and provide advice on the best temperature data logger for your needs.
