=These Hanna pH testers can be calibrated at one or two points with auto buffer recognition and against five memorized buffer values
How do you use Hanna Phep?
This pocket-sized pH tester is used by millions of people around the world to monitor pH in laboratories and industrial applications as well as in agriculture, fish farming, food manufacturing and quality control, swimming pools and the printing industry.
A universal pH meter anyone can use
HI98127 (pHep®4) and HI98128 (pHep®5) are waterproof pH and temperature meters. The housing has been completely sealed against humidity and designed to float. All pH readings are automatically temperature compensated (ATC), and temperature values can be displayed in °C or °F units.
The pHep’s ease of use in combination with its affordability made it possible for non-technical and technical personnel alike to measure pH on the spot, accurately and inexpensively throughout a variety of industries.
The pHep4 and pHep5 include features such as a dual-level LCD, battery level indicator, replaceable pH electrode cartridge, stability indicator, automatic shut-off and automatic calibration all in a floating, waterproof casing.
The pHep4 and pHep5 use the exclusive cartridge pH electrode. Electrode replacement with the stainless steel round connector means there are no pins to bend or break during replacement.
The pHep’s replaceable electrode has a pull-out cloth junction. When the cloth junction becomes dirty from routine testing, simply pull out 3 mm (1/8”) to rejuvenate the electrode.
The pHep4 and pHep5’s exposed temperature sensor provides fast response time, and its proximity to the pH electrode guarantees much more accurate temperature compensated readings.

HANNA pH TESTERS – HOW TO USE
SETUP
Setup mode allows the selection of temperature unit and pH buffer
set. To enter the Setup mode, press the /MODE button until “CAL”
on the secondary display is replaced by “TEMP” and the current
temperature unit (E.g. “TEMP °C”). Then:
• or °C / °F selection: Use the SET/HOLD button. After the temperature unit has been selected, press the /MODE button to enter the buffer set selection mode; press the /MODE
button twice to return to the normal measuring mode.
• to change the calibration buffer set: After setting the temperature unit, the meter will show the current buffer set: “pH 7.01 BUFF” (for pH 4.01 / 7.01 / 10.01) or “pH 6.86
BUFF” (for NIST 4.01 / 6.86 / 9.18). Change the set with the SET/HOLD button, then press /MODE to return to normal measuring mode
