Hanna Instruments HI98130 Combo pH/Conductivity/TDS Tester | High Range | 0–14.00 pH | 0.00–20.00 mS/cm EC | 0.00–10.00 ppt TDS | Waterproof

The Hanna Instruments HI98130 is a compact, waterproof multiparameter tester designed to measure pH, high-range Electrical Conductivity (EC), Total Dissolved Solids (TDS), and temperature in a single handheld instrument. It eliminates the need to carry separate meters for routine water-quality testing and is particularly suitable for hydroponics, aquariums, pools, ponds, water treatment and laboratory applications.

The HI98130 provides a pH range of 0.00 to 14.00, high-range EC measurement from 0.00 to 20.00 mS/cm, and TDS measurement from 0.00 to 10.00 ppt (g/L). Both pH and EC/TDS measurements feature automatic temperature compensation for more consistent readings.

Technical Specifications

Replaceable pH Electrode

The HI98130 comes with the HI73127 replaceable pH electrode. Its extractable cloth junction can help extend electrode life, while the snap-in connection makes electrode replacement straightforward. This means the complete tester does not need to be replaced when the pH electrode reaches the end of its service life.

High-Range EC and TDS Measurement

Unlike the HI98129 low-range model, the HI98130 is designed for higher conductivity and TDS applications. It measures EC up to 20.00 mS/cm and TDS up to 10.00 ppt (g/L), making it suitable for applications where a low-range tester may not provide sufficient measurement capability.

The EC-to-TDS conversion factor can be adjusted from 0.45 to 1.00, allowing the meter to be configured according to the requirements of the application.

Graphite EC/TDS Sensor

The HI98130 uses an amperometric conductivity/TDS sensor designed for reliable high-range measurements. Hanna states that its graphite conductivity probe resists contamination from salt deposits, while the exposed temperature sensor provides a fast response for temperature-compensated readings.

Automatic Temperature Compensation

Temperature affects both pH and conductivity measurements. The HI98130 automatically compensates readings for temperature variations. The temperature can be displayed in °C or °F, while the EC/TDS temperature compensation coefficient can be adjusted from 0.0 to 2.4%/°C.

Easy Calibration

The HI98130 provides automatic calibration for all major measurement functions:

pH Calibration:
Automatic one- or two-point calibration using standard pH buffers.

EC Calibration:
Automatic one-point calibration at 12.88 mS/cm.

TDS Calibration:
Automatic one-point calibration at 6.44 ppt (g/L).
