Hanna HI98130 Waterproof pH EC TDS Tester (High Range)

Hanna HI98130 pH EC TDS Tester for Hydroponics

The Hanna HI98130 is a waterproof, floating combo meter that measures pH, high-range EC/TDS (0.00–20.00 mS/cm EC; 0.00–10.00 ppt TDS), and temperature with automatic temperature compensation for accurate readings in any grow environment. Its replaceable pH electrode with extendable cloth junction extends sensor life and reduces total ownership cost. A non-fouling graphite EC/TDS probe resists salt build-up for stable, repeatable measurements, while the exposed temperature sensor speeds response and improves accuracy. With a bright, easy-to-read LCD, selectable EC/TDS conversion factor, and adjustable temperature coefficient (BETA), growers can dial in nutrient strength with confidence. Designed for daily use in reservoirs, feed tanks, and runoff, this meter helps prevent nutrient lockout and optimize uptake at every stage.

Key Hydroponic Benefits & Uses

Use the HI98130 to verify pH and EC/TDS in nutrient solutions, check source water quality, and fine-tune fertigation for healthy, vigorous growth. Perfect for DWC, ebb & flow, drip systems, coco, and soilless media where precise pH and conductivity control drive yield and quality.

Key features:

• Waterproof, floating combo meter: pH, high-range EC/TDS, and temperature in one tool

• Automatic Temperature Compensation (ATC) for accurate readings in real-world grow conditions

• Replaceable pH electrode with extendable cloth junction for longer sensor life and lower costs

• Graphite EC/TDS probe resists contamination from salts for stable, precise measurements

• User-selectable EC/TDS conversion factor and adjustable BETA to match your nutrient program
