Feature

• The pH meter offers a range of customizable user settings, including language selection, buzzer control, LCD backlight adjustment, and password protection for added security. Users can also configure the pH/ORP electrode selection, choose between manual or automatic temperature compensation, and perform pH/ORP calibration. Additionally, the device allows for modification of pH/ORP and temperature settings, setting high/low alarms for pH/ORP levels, and selecting output signal options such as 4-20mA and RS485, providing flexibility to meet various application needs.
• Equipped with an internal industrial watchdog to prevent the device from crashing.
• 2.4-inch LCD display for clear and easy readings.
• Excellent anti-interference performance for reliable measurements.
• Supports both manual and automatic temperature compensation.

Tips: What is ORP and why is it important?

ORP (Oxidation-Reduction Potential) measures the ability of a solution to either accept or donate electrons. It is a critical indicator in water treatment, chemical reactions, and biological systems. ORP helps determine the oxidative or reductive properties of the solution, which can indicate the presence of pollutants, chemical reactions, or the effectiveness of disinfection.
