Tips to Help You Buy a Temperature Data Logger
Whether you’re a beginner to data logging or have experience in the field, you need to do some serious thinking before you buy a temperature logger. To select the right instrument there are a few factors that need to be considered. Here are some tips that will help you look for a few specific features when buying a temperature data logger online.
Accuracy of Measurement
When you are measuring a parameter, you need to be aware of the accuracy requirement. This is essential especially if you are monitoring the temperature of a controlled environment since the accuracy should be up to a few decimal units. Spaces that are not temperature-sensitive can even get away with an accuracy of +/- 2 degrees. Therefore, when you are choosing a temperature data logger, be sure to check if it offers an accuracy that fits the purpose.
Data Access Methods
When you evaluate a data logger it is a good practice to look at all options available for accessing collected data from the instrument. Some temperature loggers can be connected to the computer via the USB port. Another tip is to bring the data logger to the computer since it is small and easy to move from one place to another. A device called the data shuttle can also be used to transfer information from the temperature logger to the computer. This method prevents the temperature logger from being disturbed and allows uninterrupted logging of temperature.
If the temperature data logger is to be used in an environment with extreme conditions then it should also be designed in such a way that it can withstand them. If you are going to place it in a hallway where people pass by frequently then it should be made of hard plastic and enclosed in a safety box. In an experiment that involves condensation, the temperature logger must be water-proof and moisture resistant. You can even buy protective cases separately if they are not included with the temperature data logger. These safety enclosures increase the durability of the equipment and help them last longer.
Temperature loggers generally consume very little power but since they can be used in many different ways the battery lifetime varies for each one. It is generally advised to buy a temperature data logger that lasts for at least one year. Temperature loggers are available with replaceable batteries as well however it is important to check if the replacement battery is available locally or has to be shipped by the manufacturer. Temperature loggers that operate on standard batteries are the most convenient out of all the other types.
Temperature loggers are now very low cost due to the decrease in production costs for sensors and microprocessors. Many instruments are now available at attractive prices but the cost of ownership includes the price of additional software, battery and other accessories. These expenditures should be added before deciding which one is the most economical temperature data logger.
