Questions to Ask Before Buying A Data

Questions to Ask Before Buying A Data

So you need a DAQ system. Congratulations on your decision, but, don’t rush and buy the first one you see on the market. Research. Ask questions. Here’s a list of the most important questions to ask when buying data acquisition system

What do you need it for?

Classic data logging and Data Acquisition (DAQ) solutions focus on gathering data to determine the effectiveness or upkeep timing. Try to look for a system that will fit your specific needs, maybe even go for a custom built device as well as data acquisition software.

How fast is it?

Data loggers are usually able to acquire data at speeds of up to 1Hz (once a second). More often than not, this will affect the price of a device. If you need top speed device go ahead and get one, but if your project does not require a high-speed data logger don’t waste money on that factor, invest it where you’ll need an improvement. 


Would you like to be notified instantly in case the readings are higher or lower than expected? Many devices offer the option to push notifications via SMS, email, sound an alarm or even a phone call. 

What kind of sensors do you need?

This is essential and is connected with the question number one. Don’t miss an important sensor or get those you don’t need. If you’re looking for a temperature data logger, get one with only those sensors. 


How often will you download data from the data logger and how much information will you need will give you the answer to this question. You may need only a couple of minutes a day recorded or you may want the device to save readings 24/7. 


A device can be fixed to a location or a portable one you’ll carry with you. In case the device is constantly fixed at a certain location, you’ll need to make sure it is durable for the conditions in there. If it measures water, it has to be waterproof. It may sound obvious, but many people overlook these factors and regret it later. 

These are only the essentials. There are more factors and specifications you’ll need to look into and we’ll talk about that in some of our future articles.
