USB DrDAQ pH måling-sættet hjælper dig med at foretage præcise og kontinuerlig pH-målinger.

Sammen med USB DrDAQ datalogger og software, indeholder denne pakke også en ekstern temperaturføler og en pH elektrode.

  • Måler den fulde pH-skala
  • Automatisk temperaturkompensation
  • Ingen strømforsyning nødvendig
  • Velegnet til brug både i laboratoriet og i marken

PH måle-kittet indeholder al den hardware og software, der er nødvendig for præcist at overvåge, registrere og analysere surhedsgraden af en opløsning ved hjælp af en PC.

The pH logger
The focal point of the kit is the pH logger which allows accurate pH measurements to be continuously measured and stored. The logger connects to the PC via the USB port and does not require an external power supply — making the pH Measuring Kit suitable for use both in the lab and in the field.

The pH logger uses PicoLog data acquisition software — a powerful yet flexible package that enables you to control both the frequency and quantity of measurements that are taken.

PicoLog allows the collected pH measurements to be viewed both during and after data collection, and in both spreadsheet and graphical formats. The data can then be printed, emailed or exported to other applications such as Excel.

PicoLog includes many other features — including the ability to set an alarm that will warn you if a pH value goes beyond a designated range — enabling the pH Measuring Kit to offer greater flexibility and performance than a standard pH meter.

Along with the pH logger the kit also includes a robust pH sensor that measures the full pH scale (0 to 14) together with a temperature sensor that measures temperatures from -10 to +105 °C.

Existing owners of a USB DrDAQ data logger can upgrade to a pH Measuring Kit by purchasing a pH sensor and a temperature sensor.

Automatic temperature compensation
Since pH values are temperature dependent, the pH Measuring Kit features Automatic Temperature Compensation (ATC). Using this practical solution the pH logger receives a continuous signal from a temperature sensor and automatically corrects the pH value based on the temperature of the solution.

An inexpensive answer to your data acquisition needs
By connecting suitable sensors the pH kit can also be used to measure other parameters such as temperature, light and sound — greatly expanding the capabilities of the kit.

The pH Measuring Kit is suitable for use in many industries and the educational sector, and provides accurate pH measurements and versatile pH data logging capabilities in an easy-to-use package.
