A data logger, also referred to as data recorder or datalogger, is an electronic device which was created to record data over a period of time. They are often based on a computer.
Data loggers have long replaced chart recorders when it comes to different applications. With that, many professionals are looking into purchasing their very own data loggers or data recorders. However, not all data logging products are considered great. Some actually offer poor interfaces, designs as well as functionality.
That being said, there are several factors to consider when it comes to buying the best data loggers which will offer the best features and services available.
It must have accurate measurements.
One of the main purposes of data loggers is to measure. Regardless of what you are trying to measure, the accuracy of the measurement is essential. For instance, measuring temperatures in air-conditioned places or temperature-sensitive products must be taken into account when it comes to deciding which data logger to purchase. Some professionals may need data loggers which possess the accuracy, for instance, on the order of 0.2C.
Because specifications on accuracy depend on the different types of data loggers, the buyer must know and understand well which accuracy specification is necessary for the data logger applications. You will want to avoid paying much more for an accuracy that you do not really need.
It must have a good battery life and it must be durable.
In general, when buying technological devices or gadgets, you want to make sure that you are not purchasing that lasts only 2 days or perishes after 1 month. As a general rule, do purchase a data logger that has a battery life expectancy of 1 year.
When it comes to durability, always make sure that the data logger you purchase is enclosed and designed to endure the environmental conditions of where you are intending to deploy it. If you are planning to place it in an office, the data logger should, therefore, be enclosed in hard plastic.
It must have easy options when it comes to data access.
The final purpose of collecting data is to actually view it after the monitoring period. Basically, this is why the options for data access is essential when it comes to purchasing a data logger. For instance, stand-alone data loggers make use of USB to directly transmit the data to the computer. However, we cannot deny that there are some situations wherein computers or laptops may not be available and so, data retrieval would definitely be much more difficult. This is why wireless data nodes have been dominating the data logging picture, wireless data loggers are able to relay data to a central location without the hassle of wiring, critical data points, manual retrieval and the like.
It must have good data logger resolution.
The data logger’s resolution is also an important factor. When we say resolution, this refers to the number of increments of a value in which a data logger is capable to report. For instance, a 12-bit resolution data logger can report as much as 4,000 values over a given range of temperature whereas an 8-bit may offer less number of values. However, do keep in mind that higher resolution does not automatically mean a better measurement.
These checklists are so important when purchasing your very own data logger. An example of data loggers that have the mentioned important qualities are Daqifi’s high quality DAQ systems. Daqifi’s products are some of the trusted data logging systems available for purchase. When purchasing, please go through the lists of considerations before actually making a purchase just to ensure your data logger’s worth.
