A pH meter is an electronic instrument that measures the acidity or alkalinity of solutions. Unlike litmus paper, it provides highly accurate pH readings by using glass and reference electrodes. In clinical laboratories, it is used to analyze blood and urine samples for diagnostic purposes. Food industries and environmental labs also use pH meters for testing quality and safety standards. In microbiology, it ensures proper pH adjustment in culture media preparation. Its accuracy and versatility make it an essential tool across scientific fields.
