Hanna HI 98107 Phep® Pen Type Ph Meter
The HI-98107 pHep® revolutionised the pH industry by providing non-technical personnel with a simple, inexpensive solution to accurate pH measurement. 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.
With a renewable cloth junction, the pHep® has an extended life over typical pH testers. A normal junction clogs with use over time and a typical tester would normally have to be thrown away once the junction is too contaminated. The HI-98107's junction is 2 cm long and when dirty, can be pulled out to expose a fresh section to effectively renew the pH tester's life.
The HI98107 tester features a large multi level LCD which displays both pH and temperature readings simultaneously. The pH readings are displayed with a 0.1 pH resolution and with an accuracy of ±0.1 pH. The pH range of the HI98107 is from 0.0 to 14.0 pH. An exposed temperature sensor allows for rapid automatic temperature compensated pH measurements. Temperature can be set to display in ℃ or ℉. The LCD screen has stability and calibration tag indicators. The battery percent level is displayed at start up alerting the user to the remaining battery power that is available.
Calibration is performed by pressing the dedicated calibration button. Once in calibration mode the pH electrode can be calibrated to 1 or 2 points using the pre-programmed standard buffers (pH 4.01, 7.01,10.01). When the standard value is recognized and stability is reached, the meter automatically accepts and stores the calibration value.
Setup options include automatic shut off timing and temperature unit displayed. Automatic shut-off options are to turn the meter off after 8 minutes, 60 minutes, or disabled. To enter the setup mode the user presses a button located in the battery compartment.

Multi-Level LCD
The large LCD displays pH, Temperature, Calibration buffer tags, battery level and instability indicator.
Sensors
An exposed temperature sensor along with an extractable cloth junction ensures a fast and stable temperature compensated measurement.
Two-Button Operation
Only two buttons for meter operation. One for on/off and one for calibration.
Features / Benefits
Slim, Ergonomic Design
With rounded edges and a case that is only 17 mm (0.7") thick, the HI98107 is thin and fits comfortably in the hand or pocket.
Stability Indicator
A clock tag stability indicator will disappear to alert the user when the reading is stable.
Large Multi-level LCD
The LCD is 29 mm (1.125") x 20 mm (0.81") allowing the user to easily read both the pH and temperature simultaneously.
Automatic Shut-off
User-selectable time until meter shuts off to conserve battery life. Options are 8 min, 60 min or disabled.
Two-button Operation
One for ON/OFF, the other for calibration.
Low Battery Indicator
Low battery indicator that is displayed when less than 10% battery life is remaining.
Integrated Temperature Sensor
Built in temperature sensor allows for temperature compensated measurements. Temperature can be displayed in either °C or °F.
Battery % Level at Startup
At start-up, all the LCD segments are displayed for 1 second, then the percent indication of the remaining battery life is displayed.
Automatic Calibration
Automatic calibration to one or two points using standard buffers (pH 4.01, 7.01 and 10.01).
