Desktop Dissolved Oxygen Meter/Conductivity /PH Meter — PH219/PH220/EC032/ORP171

Desktop pH meter is an essential analytical instrument designed for precise measurement of acidity or alkalinity in a solution. It operates by measuring the potential difference between a pH electrode and a reference electrode. Known for high accuracy and stability, these benchtop units are ideal for laboratory environments, quality control, and various industrial processes. They often feature automatic temperature compensation, data logging, and connectivity to computers for detailed analysis. Regular calibration with standard buffer solutions is crucial for maintaining measurement integrity.

Dissolved oxygen (DO) meter measures the concentration of oxygen gas dissolved in a liquid, typically water. This parameter is vital for assessing water quality in aquatic ecosystems, wastewater treatment, and aquaculture. The most common type uses an electrochemical or optical (luminescence) sensor. Benchtop models provide high precision and are suited for laboratory analysis of collected samples. Monitoring dissolved oxygen is critical for understanding biological activity, process efficiency, and ensuring the survival of aquatic life, making it a cornerstone of environmental and industrial testing.

Desktop conductivity meter measures the ability of an aqueous solution to conduct an electric current, which is directly related to the concentration of ions present. This makes it a fundamental tool for assessing water purity, salinity, and total dissolved solids (TDS). These robust benchtop instruments are widely used in laboratories for testing everything from ultrapure water to industrial wastewater. They work by applying an AC voltage between two electrodes and measuring the resulting current. The results provide valuable insights for quality control in pharmaceutical, environmental, and chemical applications.
