Hanna Portable pH/EC/TDS/Temperature Meter, EC range: 0 to 1990 µS/cm, TDS range: 0 to 1990 ppm (mg/L) - HI9812-51

Hanna HI9812-51 Portable pH/EC/TDS/Temperature Meter is a reliable and economical multi-parameter instrument designed for accurate water quality analysis in laboratory, industrial, agricultural, and field environments. This robust handheld meter enables simultaneous measurement of pH, electrical conductivity (EC), total dissolved solids (TDS), and temperature, making it an efficient all-in-one solution for comprehensive water testing.

The instrument is equipped with the HI1285-5 multi-parameter probe, an amplified 3-in-1 sensor that integrates pH, EC/TDS, and temperature measurement into a single unit. This design reduces handling complexity, minimizes maintenance, and ensures stable readings even in electrically noisy environments such as near pumps or industrial equipment.

With a wide measurement range of pH 0.0 to 14.0, EC 0 to 1990 µS/cm, TDS 0 to 1990 ppm, and temperature 0 to 50°C, the HI9812-51 is suitable for diverse applications including water treatment, hydroponics, environmental monitoring, and laboratory analysis. Automatic temperature compensation ensures accurate EC, TDS, and pH readings despite fluctuations in sample temperature.

The large LCD display provides clear measurement readings along with status indicators and operational prompts, making the instrument easy to use for both professionals and new users. Manual single-point calibration for pH and EC/TDS allows precise adjustment and supports consistent, repeatable measurements aligned with standard operating procedures.

Built for durability, the HI9812-51 features a rugged and waterproof construction, ensuring reliable performance in harsh and humid environments. Its compact and lightweight design (145 × 80 × 36 mm, 230 g) enhances portability, making it ideal for on-site testing and field applications.

Powered by a standard 9V battery, the meter delivers up to 150 hours of continuous operation, ensuring uninterrupted performance during extended use. The included 1 meter probe cable with 8-pin DIN connector offers flexibility and ease of measurement across various setups.

Widely used in laboratories, agriculture, water treatment plants, and environmental monitoring programs, the HI9812-51 provides dependable and accurate multi-parameter measurement for effective water quality management.
