Display: Handheld pH meters come with either an analog or digital display. Most modern models use digital displays, which are easy to read and offer more precise readings.
Accuracy and Range: Handheld pH meters are usually accurate within ±0.1 pH units, though higher-end models may offer precision to ±0.01 pH. The typical range for pH meters is 0 to 14, covering the full acidity (0) to alkalinity (14) spectrum.
Electrode: The electrode is the part of the meter that comes into contact with the solution being tested. Most handheld pH meters come with either a glass or plastic electrode, and some models are designed to be replaceable, while others are built-in.
Calibration: To ensure accurate measurements, pH meters must be calibrated regularly, usually with standard buffer solutions. Many handheld models allow for automatic calibration, while some may require manual input.
Portability: These meters are lightweight and easy to carry, making them ideal for field testing. Many are designed to be durable and waterproof, allowing use in various environments such as agriculture, water quality testing, food processing, or scientific experiments.
Battery Powered: Handheld pH meters are typically battery-powered, which makes them convenient for use in remote areas without easy access to power outlets.
