What can I measure with a water data logger?

If you work for a water board or conduct scientific research, then being able to monitor the quality of groundwater and surface water easily is of great help. You can do this with the help of a water data logger. A water data logger gives you information about temperatures, cloudiness or light transmission, pH values, dissolved oxygen, conductivity and salinity of water. A water data logger also gives you information about water levels.

Water data loggers continuously record the water quality without you having to do anything yourself, making forgotten measurements or lost papers a thing of the past. Comprehensive, user-friendly analysis software helps you chart all measured values.

 

You can easily retrieve readings from your water data logger using Bluetooth or other connection methods.

A water data logger records exactly the values you want to measure. This information can be checked periodically. This can be done on-site either with a single universal, handy and waterproof ONSET mobile reader or with a cable and a laptop. Since recently, Pedak has also been supplying ONSET Hobo Data loggers with Bluetooth connectivity. You can retrieve data using your phone or tablet without the need for a reader. So it’s even faster and more convenient!

 

Which water data logger do you need?

Choosing the best water data logger depends on what you want to use it for. There are water data loggers that measure temperature and light. Other loggers measure conductivity, pH values, dissolved oxygen (DO) or water levels. Sometimes, you will find various options are available among the different types of water data loggers.

It is handy to ask yourself some questions in order to determine the best choice of water data logger for you.

  • How accurate does your water data logger need to be? Do you only need to see that changes are taking place, or do you want to measure, say, conductivity values or the water level to a very accurate degree?
  • At what depth do you want to take measurements?
  • Do you want to be able to check easily the collected data on-site?
  • Will you be taking readings in an estuary or an area exposed to fresh, salt or brackish water? Choose your water data logger accordingly.
  • Check the water data logger’s response time. Do you need to take readings every second, every minute, every 15 minutes or every hour?
  • Is it important that the sensor is easy to clean?
  • Check whether you can easily sink the water data logger. Do you need a weight for this purpose?
  • How do you want to fix the water data logger in place? For example, does it need to have a mounting eye?
  • The smaller the water data logger, the easier it is to handle and hide. What is important to you?
  • A water data logger with an optical interface in the housing prevents water damage or errors when retrieving the collected data. A mechanical plug-in connection is a weak point in the waterproofing.

 

What requirements does the software of your water data logger need to meet?

The software that analyses and displays the collected data must be user-friendly and compatible with your operation. When choosing the software, check whether it meets your requirements. Here are some other helpful tips:

  • Check whether you can configure and retrieve data from the device wirelessly.
  • Will you receive alarms without logging in?
  • Check whether it is possible to enter your own coefficients.
  • Do you need software to compensate for other parameters?
  • Check whether it is easy to enter calibration points.
  • Check whether you can combine measurement data from different data loggers on one graphic display.
  • Choose software that allows the easy export of data, say, onto a spreadsheet. It is also handy if it lets you copy charts and other graphic representations into other programmes for creating reports.
  • The software should make it possible to save any changes you make to charts.
  • Can you share measurement data directly using WhatsApp or email, and can you upload it to a server or network printer?

 

As you can see, there is a lot to consider when you are looking for a water data logger.
