Hanna (HI98128) pHep 5pH-Temperature Tester, 6-25-64" Length x 1-19-32" Width x 1" Height
HI98128 pHep 5 pH & Temperature Tester
The Hanna HI98128 pHep 5 combines laboratory accuracy with field durability in a pocket-sized tester. Automatic two-point calibration and built-in temperature compensation ensure reliable pH readings from 0.00 to 14.00 pH, while the replaceable electrode design extends the working life well beyond disposable testers.
Three-Part Testing System
Automatic Two-Point Setup
Microprocessor recognizes standard pH buffers at 4.01, 7.01, and 10.01 and calibrates automatically with temperature compensation from 0 to 50°C. No manual adjustments or guesswork required.
High-Resolution pH Detection
Glass electrode sensor delivers 0.01 pH resolution with accuracy to ±0.05 pH. Digital display shows both pH and temperature simultaneously for complete water analysis in one reading.
Field-Replaceable Sensor
HI73127 pH electrode unscrews for replacement when sensitivity declines. Extends tester lifespan indefinitely compared to sealed disposable meters, reducing long-term cost per test.
Designed for Isopure Systems & Beyond
Works with all Isopure reverse osmosis systems including WP-4V, WP-5, 4SV, and 5SV models for post-filtration verification. Also ideal for Zero Waste system monitoring, aquarium maintenance, pool balancing, hydroponics, and drinking water quality checks. Compact 6.4" length fits in pockets and toolkits for field testing anywhere water quality matters.
