Hanna Portable Waterproof pH/EC/TDS Meter (High Range) - HI991301

The Hanna HI991301 Portable Waterproof pH/EC/TDS Meter is a high-performance multi-parameter instrument designed for versatile laboratory and field analysis. It provides direct and accurate measurement of pH, electrical conductivity (EC), total dissolved solids (TDS), and temperature using a single pre-amplified HI12883 probe. This meter is rated IP67 for complete waterproof protection, making it suitable for harsh industrial, environmental, and laboratory scenarios.

Key features include highly accurate readings (±0.02 pH, ±2% EC/TDS, ±0.5°C), automatic temperature compensation for all parameters, and an advanced probe with easy-to-clean sensors and a renewable cloth junction. The meter enables automatic calibration, standardized buffer recognition, and user-selectable TDS factors and temperature coefficients for consistent and reproducible results. Its digital interface displays calibration information, probe diagnostics (including CAL Check and sensor status), and user-selectable shutoff timing (8 min, 60 min, or disabled).

• Measures pH, EC, TDS, and temperature in one meter for comprehensive water quality analysis.
• Wide measurement ranges: pH from -2.00 to 16.00, EC 0.00–20.00 mS/cm, TDS 0.00–10.00 ppt, temperature -5.0 to 105.0°C.
• Automatic calibration and temperature compensation for all readings ensure accuracy and reliability.
• HI12883 multi-parameter probe features internal temperature sensor, quick-connect DIN connector, and durable PVC body.
• Selectable TDS conversion factor (0.45–1.00) and temperature correction coefficient β (0.0–2.4%).
• IP67-rated waterproof meter and probe guarantee durability in challenging laboratory, industrial, and field environments.
• Battery operated (3 x AAA), with up to 600 hours of continuous use.
• Compact and lightweight design (154 × 63 × 30 mm, 196 g) for convenient transport and use on site.
• Used in water treatment, environmental monitoring, food production plants, chemical manufacturing, research laboratories, industrial quality control, and wastewater facilities.
• Supplied with HI12883 probe and operates from 0 to 50°C and up to 100% relative humidity.
