Product Description

The HI9813-51 Portable pH/EC/TDS Meter provides accurate measurement of pH, electrical conductivity (EC), total dissolved solids (TDS), and temperature in one robust and portable unit. With a wide pH range from 0.0 to 14.0, EC range from 0.00 to 4.00 mS/cm, and TDS range from 0 to 1999 ppm, this instrument is suitable for laboratory, hydroponics, greenhouse, and field applications. Its water-resistant design and clear LCD make it ideal for on-site testing where reliability and accuracy are critical.

Measures four key parameters: pH, conductivity, TDS, and temperature, streamlining water quality analysis in industrial, agricultural, and research settings.
Includes a multi-parameter HI1285-5 combination probe with built-in temperature sensor and a 1 m cable for flexibility and ease of measurement.
Manual, single-point calibration for both pH and EC/TDS ensures reliable and repeatable results with user control.
pH accuracy is ±0.1 pH, EC/TDS accuracy is ±2% Full Scale, and temperature is automatically compensated using a fixed β of 2%/°C.
Features variable EC to TDS conversion factor for more accurate reflection of natural water characteristics (0.56 to 0.72 according to TDS 442 curve).
Durable design with a weight of 230 g and compact dimensions of 145 x 80 x 36 mm for high portability and ergonomic operation.
Device is powered by a 9V battery, supporting approximately 150 hours of continuous use, perfect for long testing campaigns and outdoor use.
Water-resistant body withstands environments with high humidity and temperature variations (0 to 50°C, up to 100% RH).

Typical use cases include laboratory, greenhouse, hydroponics, agricultural, and water quality monitoring in research, industrial, and commercial sectors. Package includes HI1285-5 combination probe. For more laboratory meters and water analysis instruments, continue browsing the EnvMart catalog.
