Introducing the Vision Plus pH/mV/Temp Meter

The Vision Plus pH/mV/Temp Meter is a reliable water quality meter offering a high level of accuracy and a plethora of user-friendly features at an attractive price point for a professional style meter.

Vision Plus pH/mV/Temp Meter Features & Benefits

Functional: The built-in microprocessor stores, calculates and compensates for all parameters related to pH measurements, including pH electrode temperature characteristics, electrode slope deviations and buffer solutions.
Lifeproof: The case is shockproof and rated IP67 waterproof and dust-proof. The 3-in-1 pH/ref/temperature electrode is fitted with special connectors that maintain the IP67 rating.
Extra-large LCD: The displays pH or mV and temperature values simultaneously.
Autolock: The auto-lock feature helps ensure accurate measurements by automatically sensing the endpoint of pH and mV measurements and freezing the reading on the LCD.
Automatic or manual temperature compensation: Automatic temperature compensation can be switched on or off to suit all possible measuring applications.
Selectable buffers: Choose between USA or NIST buffer sets to complete pH calibration.
Easy calibration: Easily perform two or three-point calibration as the Vision Plus pH/mV/Temp meter prompts you through the calibration procedure.
On-screen electrode efficiency: The Vision Plus pH/mV/Temp Meter displays electrode efficiency on the LCD to ensure consistent and precise measurements. This feature also helps you know exactly when it is time to calibrate or replace the pH electrode.
Straightforward navigation: Dedicated operation buttons ensure intuitive operation, easy measurement and seamless calibration.
