ADWA Waterproof TDS Tester Model AD31 | Professional EC, TDS & Temperature Meter

Product Description

The ADWA Waterproof TDS Tester Model AD31 is a high-performance digital water quality testing instrument designed for accurate measurement of Electrical Conductivity (EC), Total Dissolved Solids (TDS), and Temperature in a single compact device. Developed by ADWA Instruments, this professional-grade tester is widely trusted by laboratories, research facilities, water treatment plants, pharmaceutical industries, food processing industries, educational institutions, environmental monitoring organizations, and agricultural professionals for its precision, durability, and ease of use.

Built with an IP67 waterproof housing, the AD31 is engineered to withstand demanding laboratory and field conditions. Its rugged waterproof construction protects the instrument from accidental water exposure, making it ideal for both indoor laboratory work and outdoor water quality testing. Whether you are testing drinking water, purified water, RO water, industrial process water, wastewater, aquaculture systems, hydroponic nutrient solutions, or environmental water samples, the AD31 delivers fast, stable, and highly reliable results.

One of the key advantages of the AD31 is its ability to measure three essential water quality parameters—EC, TDS, and Temperature—using a single handheld device. The built-in Automatic Temperature Compensation (ATC) automatically adjusts readings according to sample temperature, ensuring exceptional measurement accuracy even when water temperature fluctuates. This feature significantly improves reliability during laboratory analysis and field testing.

The AD31 is equipped with a large, easy-to-read LCD display that provides clear measurement values even under different lighting conditions. The display also includes stability indicators and battery status notifications, allowing users to monitor the instrument’s operating condition at all times. Its automatic one-point calibration system makes calibration simple and quick, helping laboratory professionals maintain accurate and repeatable measurements without complicated procedures.

For long-term operation, the instrument features a replaceable graphite electrode, reducing maintenance costs and extending the overall service life of the tester. The high-quality sensor provides excellent chemical resistance and consistent measurement performance across a wide range of water samples. The automatic power-off function helps conserve battery life during extended laboratory use, making the instrument energy-efficient and convenient for daily applications.

The ADWA Waterproof TDS Tester Model AD31 is extensively used in research laboratories, pharmaceutical manufacturing, biotechnology laboratories, environmental analysis, food and beverage quality control, chemical industries, educational institutions, aquaculture farms, hydroponic cultivation, agriculture, wastewater treatment plants, and municipal water supply monitoring. Its compact pocket-sized design makes it highly portable, allowing technicians and researchers to carry it easily for on-site testing.

Whether you are performing routine laboratory analysis, monitoring industrial water quality, testing drinking water purity, or conducting scientific research, the AD31 provides dependable performance with excellent accuracy, reliability, and ease of operation. Its professional features, durable construction, and trusted ADWA quality make it one of the most popular portable EC and TDS meters available for laboratory and industrial applications.
