pH meter EzpH-L: Compact, accurate, and flexible for every lab

The EzpH-L pH Meter by Electrolab is a compact and powerful measurement solution, designed to deliver high accuracy in a flexible benchtop design. With professional calibration capabilities, an integrated rechargeable battery, and GLP compliance, the EzpH-L is the ideal tool for labs with limited space, applications requiring mobility, or educational institutions.

Key features of the EzpH-L pH meter

This product focuses on core functionalities, delivering reliability and efficiency in a practical design.

Professional calibration and high accuracy

The EzpH-L supports up to 5-point pH calibration, using international standard buffer sets (USP, NIST) or custom buffers. The auto buffer recognition and Automatic Temperature Compensation (ATC) features help eliminate errors, ensuring measurement results with high accuracy and repeatability (±0.01 pH).

Compact and flexible design with a rechargeable battery

With its small footprint and light weight, the EzpH-L saves valuable bench space. Notably, the instrument is equipped with a rechargeable battery, allowing users to easily move it and perform measurements in locations without direct power access, offering maximum flexibility.

GLP compliance and data connectivity

The device meets GLP (Good Laboratory Practice) requirements by storing and exporting fully documented reports. It can store multiple reports in its memory and can be connected to a computer via an RS 232 port for data transfer, suitable for record-keeping and management.

Frequently asked questions (FAQ)

1. What is the main difference between the EzpH-L and the EzpH (touch screen) model?
The EzpH-L is a more compact version that uses a graphic LCD and a membrane keypad, and it includes a rechargeable battery for flexibility. The EzpH model has a larger 7-inch color touch screen, more memory, and more modern USB connectivity, but it does not have a battery.

2. What does “Auto buffer recognition” mean?
When you immerse the electrode in a standard buffer solution (e.g., pH 4, 7, 10), the meter automatically recognizes the pH value of that solution and prompts for calibration at that point. This makes the calibration process faster and reduces errors.

3. Is this meter truly portable?
Yes. Thanks to its compact design and integrated rechargeable battery, you can easily carry the meter to different locations within the lab or even take it into the field to perform measurements without relying on a power outlet.

4. How do I connect the meter to a computer?
You can connect the EzpH-L to a computer via its RS 232 communication port. You may need an RS 232 to USB adapter cable if your computer does not have a serial port.

5. What other parameters can this meter measure besides pH?
In addition to pH, the meter can also measure Oxidation-Reduction Potential (ORP) by connecting an ORP electrode, relative mV, and the temperature of the solution.
