Hanna Portable pH/EC/TDS meter, range: pH 0.0 to 14.0 pH EC 0.00 to 4.00 mS/cm TDS 0 to 1999 ppm (mg/L) - HI9813-51

Hanna HI9813-51 Portable pH/EC/TDS Meter is a reliable and versatile multi-parameter instrument designed for accurate measurement of pH, electrical conductivity (EC), total dissolved solids (TDS), and temperature in a wide range of applications. With a broad measurement range of pH 0.0 to 14.0, EC 0.00 to 4.00 mS/cm, and TDS 0 to 1999 ppm, this meter is ideal for laboratory analysis, hydroponics, greenhouse monitoring, agriculture, and field-based water quality testing.

The instrument is supplied with the HI1285-5 multi-parameter combination probe, which integrates pH, EC/TDS, and temperature sensors into a single unit. This design simplifies operation, reduces handling errors, and enhances efficiency during routine testing. The built-in temperature sensor enables automatic temperature compensation, ensuring accurate readings even when sample temperatures fluctuate.

Designed for precision and control, the HI9813-51 offers manual single-point calibration for both pH and EC/TDS, allowing users to fine-tune measurements according to their specific requirements. It features a variable EC to TDS conversion factor (0.56 to 0.72), enabling more accurate representation of natural water characteristics based on the TDS 442 curve.

The meter delivers dependable accuracy with ±0.1 pH for pH measurements and ±2% full scale for EC and TDS. Its large LCD display provides clear and easy-to-read results, while the intuitive interface ensures smooth operation for both professionals and beginners.

Built for durability, the HI9813-51 features a water-resistant enclosure that performs reliably in humid and challenging environments. It operates within a temperature range of 0 to 50°C and up to 100% relative humidity, making it suitable for both indoor and outdoor applications.

Compact and lightweight (230 g, dimensions 145 × 80 × 36 mm), the meter is easy to carry and handle, making it ideal for fieldwork and on-site testing. Powered by a 9V battery, it offers up to 150 hours of continuous operation, supporting extended usage without frequent battery replacement.

Widely used in laboratories, hydroponic systems, greenhouse environments, agricultural irrigation, and industrial water analysis, the HI9813-51 provides a comprehensive solution for multi-parameter water quality monitoring.
