This pH meter measures the pH of aqueous liquids via a detachable sensor for a quick and accurate interpretation of the results of the measurements using the galvanic voltage difference between acidic, neutral and basic liquids at the probe tip. In addition, this device has two setting potentiometers for calibrating the pH4 or pH7 values and a matching screwdriver, as well as a neutralisation fluid for the sensor and corresponding calibration solutions. Measured values are clearly displayed by the white backlight and the large LCD display and can be read without any problems. This model is powered by a standard 9-V battery. Due to the handy design, the large display and the extensive accessories, this measuring device is especially suitable for use in schools and education, as well as science and research.
