Hanna (HI98107) pHep Economical pH Tester
HI98107 pHep Economical pH Tester
Affordable, field-proven pH measurement with renewable junction technology for extended service life
The Hanna HI98107 pHep revolutionized pH testing by giving non-technical users an accurate, economical solution trusted by millions worldwide. Unlike disposable testers that must be discarded when the junction clogs, the pHep features a 2 cm renewable cloth junction that extends usable life significantly. With ±0.1 pH accuracy across 0.0 to 14.0 pH range and up to 700 hours of continuous operation on a single set of batteries, this tester delivers reliable results in labs, agriculture, aquaculture, food production, pools, and industrial quality control.
What Makes the HI98107 pHep Different
Renewable Junction
2 cm cloth junction can be pulled out to expose fresh sections when contaminated, extending tester life far beyond typical disposable units
700-Hour Battery Life
Four 1.5V batteries provide approximately 700 hours of continuous use, delivering years of testing before replacement needed
Manual Calibration
Simple 1 or 2-point calibration using side-mounted trimmer, no complex menus or technical expertise required
0.1 pH Resolution
Measures 0.0 to 14.0 pH range with 0.1 pH resolution and ±0.1 pH accuracy for reliable field and lab results
Compact & Portable
Lightweight design at just 95 grams (3.4 oz) and 175 x 41 x 23 mm dimensions for easy field transport
Wide Operating Range
Functions reliably in 0 to 50°C (32 to 122°F) environments with up to 95% relative humidity
Where the HI98107 Excels
The Hanna HI98107 pHep is widely used across laboratories, industrial water treatment, agriculture, fish farming and aquaculture, food manufacturing and QC, swimming pool maintenance, hydroponics, and printing operations. Its economical design and renewable junction make it ideal for environments where multiple users need routine pH monitoring without the cost and complexity of higher-end meters.
Trusted by millions of users worldwide, the Hanna pHep HI98107 has set the standard for affordable, accurate pH testing since its introduction.
