Data loggers are electronic devices that, over time, records information with an instrument or sensor which are either built in or external ones. They are usually portable, battery powered and small which are equipped with internal memory used for info storage and microprocessor. Some use personal computers with a software that interface and activates them or have a local interface.
They have varying purposes for general measurement applications or for specific ones and are left unattended after activation for a certain duration. Data logging sensors could be programmed but others may be static with limited changes allowed for their parameters. Here are several tips when buying one for your particular need.
Determine the necessary measurement accuracy which depends upon the info you will be monitoring like the temperature inside the room or storage. They have varying specifications and it will help you avoid to pay more unnecessary accuracy when the requirements are understood. Another essential factor is resolution though the accuracy is not guaranteed with a higher resolution.
Information in these devices could be accessed in varying ways with some using USB interface connected directly to computers. But bringing the computer to site or the device back to office is an impractical and inconvenient activity. You can use instead a data shuttle which could retrieve info they collected and not interrupt or move the logger.
They have many different software packages for graphing and analysis but look for intuitive ones that have minimal learning curve. Their tasks such as offloading data, launching the logger and configuring parameters must be done quickly and easily. They must be capable in plotting, cropping, appending and merging information which can be exported easily.
When you purchase them, make sure environmental conditions of that area you would place them can be withstood by their enclosure. Hard plastic would be enough to monitor office hallways while non condensing areas need one that has moisture protection. Inquire the availability of protective cases that suits situations which require increased protection and durability.
These devices consume very low energy but their battery life varies greatly because their sample rates might not be similar with the environmental conditions. Make sure to select one which has a battery that will last for one year at least. Inquire if their batteries could be easily replaced by users and if specialized batteries are used or standard household ones only.
Loggers are generally easy to use and technical assistance is rarely required even when you have just started using them. But due to it being a highly technological product, you may have questions about them so find out if your supplier have support services. These should preferably include telephone and internet based resources and their financial stability would indicate they may last long and can help you longer too.
Find a supplier offering reliable performance in various monitoring environment like indoors, underwater, or outdoors. This would be your assurance about how knowledgeable and expert they are in assessing, meeting and understand your future and current needs. Ask about alarm capabilities if ever the environmental conditions would not meet the tolerance range you set.
