        Major Tech MT115 | pH and Temperature Meter

        The Major Tech MT115 is a precision digital meter designed to measure pH and temperature in various liquid solutions. Whether you're testing pool water, monitoring industrial processes, or conducting agricultural and environmental research, this meter delivers accurate results with automatic temperature compensation and calibration.

        It features a dual LCD display that simultaneously shows pH and temperature readings, while a red backlight alarm warns users when pH levels fall outside the safe range (below 3.5 or above 11.5). The data hold function allows users to save readings for later review, and memory retention ensures stored data remains even after the device is powered off. With automatic shutoff after 10 minutes of inactivity, the MT115 helps conserve battery life, making it a practical tool for professionals on the go.

        • Automatic calibration & temperature compensation – Ensures precise readings in different conditions.
        • Data hold & memory retention – Saves readings even after the meter is turned off.
        • Auto power off & low battery indicator – Helps extend battery life and prevent downtime.
