J-3F Laboratory pH Meter is a precision instrument designed for accurate pH measurement in scientific, industrial, and educational settings. Featuring a high-sensitivity glass electrode and a reliable reference electrode, it ensures stable and repeatable readings with a resolution of 0.01 pH and an accuracy of ±0.02 pH. Its wide measuring range (0–14 pH) and temperature compensation (0–60°C) enhance versatility across diverse samples.

The compact, user-friendly design includes a large LCD display for clear readings and intuitive calibration controls (typically 3-point calibration with standard buffer solutions). Some models offer automatic temperature compensation (ATC) and data hold functions for convenience.

Ideal for laboratories, environmental testing, and quality control, the J-3F combines durability with consistent performance, making it a trusted tool for pH analysis. Its affordable price and low maintenance further add to its practicality for routine applications.
