The HI98107 pHep® is an easy-to-use pH water tester that makes monitoring water quality simple. This accurate pH tester features 0.1 resolution with automatic two-point calibration and temperature compensation in a single, portable, pocket device.
Compact design fits right in your pocket so you can take it anywhere.
Cloth junction providing a larger surface area than a standard ceramic junction
Great for drinking water, aquariums, pools, & ponds.
The HI98107 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.
The pH electrode uses a unique reference cell design that utilizes a cloth junction that provides a larger surface area than a standard ceramic junction.
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 water pH 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 pH water tester operation. One for on/off and one for calibration.
Features and 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.
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.
Two-button Operation
One for ON/OFF, the other for calibration.
Integrated Temperature Sensor
Built in temperature sensor allows for temperature compensated measurements. Temperature can be displayed in either oC or oF.
Automatic Calibration
Automatic calibration to one or two points using standard buffers (pH 4.01, 7.01 and 10.01).
Stability Indicator
A clock tag stability indicator will disappear to alert the user when the reading is stable.
Automatic Shut-off
User-selectable time until water pH meter shuts off to conserve battery life. Options are 8 min, 60 min or disabled.
Low Battery Indicator
Low battery indicator that is displayed when less than 10% battery life is remaining.
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.
