• pH range: -2.000 to 20.000 pH; mV conversion: ±2000.0 mV; temperature: -20.0 to 120.0 °C, -4.0 to 248.0 °F

• Designed specifically for acidity-pH measurement and analysis of samples in agriculture/gardening/soil industries

• Large LCD screen display allows you to easily view pH, pH-mV, temperature measurement readings and instrument performance status from multiple angles; features a carefully designed Sensor Check™ function that allows users to check electrode status at any time;

• Automatic endpoint locking function can lock stable readings on the LCD, making it convenient to read measurement results and record them; USB data interface, 200 data records [100 pH reading records, 100 mV reading records];

• GLP function, query acidity-pH calibration data, up to five-point automatic recognition calibration and five-point custom calibration, built-in seven standard calibration points, messages on the graphical LCD, allowing easy and accurate calibration

• New design, rugged and durable, built-in amplifier and temperature sensor conical glass acidity-pH electrode, convenient and quick setup and calibration modes, making the meter easier to operate.

Waterproof:

Ergonomic, rugged and durable waterproof (IP67) design, able to withstand harsh environments

Automatic calibration :

HI98168 can connect 5 points, including custom buffers. Calibration buffers are automatically recognized; after calibration, the buffer values used will be displayed on the screen

Calibration check:

• Alerts the user to potential problems during calibration, including when to clean the electrode and possible buffer contamination.

• Displays the overall condition of the pH electrode after calibration based on offset and slope characteristics

GLP data:

GLP data can be viewed at any time, including recorded readings. Calibration data includes date, time, pH calibration buffers, offset and slope.

Dot matrix LCD screen:

The high-contrast graphical LCD screen is easy to view in bright sunlight as well as in low-light areas with backlight. The combination of dedicated and virtual keys allows easy, intuitive operation of the meter in multiple languages.

On-demand logging:

Record up to 100 samples on demand (100 pH/100 mV)

PC connection:

Sealed optically isolated USB connects to a PC via micro USB cable and a PC running HI92000 software

Intuitive dot matrix display:

HI98168 features a backlit graphical LCD design. It has virtual keys, battery status indicator and error messages. Users will find the meter interface intuitive and easy to read. A dedicated help key provides information related to the current meter operation and can be used at any stage of the setup or measurement process to display context-sensitive help.

Automatic buffer recognition:

• Low battery indicator, optional auto-off.  

• Auto power off: user selectable: 5, 10, 30, 60 minutes or can be disabled
