Product Description
Monitoring of water resources has become a global challenge with high priority.  Therefore innovative measuring technology is essential to meet the challenge.  The WQL-pH, pH dataloggers are the first launched product of the new WTW product family.  The pH dataloggers meet the requirements of continuous long-term pH measurement and data logging.  Applications for the WQL-pH, pH Dataloggers are characterized by the need for a large quantity of reliable data measurements at multiple measuring positions which are difficult to access.  With a diameter of only 1 inch (25 mm) the pH dataloggers are ideal for both ground and surface water monitoring projects.  The pH dataloggers consist of four parts including the end cap which covers the USB data transfer port, the main body which houses the battery, the replaceable long life pH electrode, and the guard that protects the pH electrode.
pH Datalogger's USB port, indicator light, and quick start button. pH Datalogger's battery compartment.
The pH datalogger's huge memory can record up to 600,000 data sets containing the pH measurement, temperature, date, and datalogger ID number.  This massive amount of data storage is ideal for detailed pH monitoring studies.  The data is recovered from the pH dataloggers using a mini USB connection for fast data transfer directly to a PC.  The pH dataloggers have a status LED which provides information on memory and measurement operation.  A quick start button located under the pH datalogger's end cap allows you to have further control over the pH measurements. pH Datalogger Software
A user-friendly software interface allows you easy and fast access to all important functions and settings on the pH datalogger.  The software allows you to easily follow the pH datalogger's detailed one or two point calibration protocol and configure several key parameters including time interval, starting and stopping point, and the datalogger's ID.  The pH datalogger software includes a graphing function to simplify data analysis.  The pH datalogger's software can pre-filter the data by date and time then easily export the data via .CSV format to other software programs for more detailed analysis. Power for the pH Datalogger
The pH datalogger uses a high quality lithium battery as its power source.  The pH datalogger uses special intelligent battery power management to maximize the battery life.  While the battery life is dependent upon the frequency of measurement, the battery can last up to 16 months with a sample rate of 10 minutes or more.  Changing the battery is as easy as opening the conveniently located battery compartment on the pH datalogger's main body. pH Datalogger Electrodes
The pH dataloggers use the SensoLyt pH electrode or ORP electrode, both with integrated temperature sensor and extremely stable polymer reference electrolyte allowing for precise measurement over a long period of time.  The pH datalogger and electrodes have a robust design with an IP 68 rating which can withstand depths up to 328 ft (100m).  The pH datalogger's electrodes are replaceable and has a SMEK plug for easy removal and installation.  The stainless steel basket guard provides complete protection to the pH datalogger's electrodes.
