Calibration - Up to a five-point calibration with seven standard buffers and five custom buffers

Approximately 200 hour battery life - Powered by four 1.5V AA batteries

Clear display - Dot matrix display with multi-function virtual keys

Auto hold - Automatically holds the first stable reading on the display

Calibration timeout - Alerts when calibration is due at a specified interval

Connectivity - PC connectivity via opto-isolated micro-USB with HI-92000 software

GLP - GLP data provides data from previous calibration to ensure Good Laboratory Practices are met

Intuitive keypad - Important and often used functions such as GLP information, help, range, calibration and backlight have a dedicated button

Backlit Graphic LCD Display - These meters feature a backlit graphic LCD with on-screen help. The graphic display allows for the use of virtual keys to provide for an intuitive user interface.

More about the meter's features

Waterproof Protection - The meter is enclosed in an IP67 rated waterproof casing and can withstand immersion in water at a depth of 1 m for up to 30 minutes.

Quick Connect Probe - Each meter features an application specific pH/temperature probe with a quick connect DIN connector to make attaching and removing the probe simple and easy.

Calibration Timeout - Alerts when calibration is due at a specified interval.

pH Calibration - Choose from seven standard pH buffers and five custom values to obtain up to five point calibration and achieve high precision readings with a 0.001 pH resolution and a pH accuracy of +/-0.002.

Enhanced Calibration - An “out of calibration range” warning can be engaged to keep the user informed of the current calibration and help to avoid performing measurements that are out of the bracketed range.

CAL Check™ - Hanna’s CAL Check maintains a history of past calibrations and monitors the pH electrode and buffers during subsequent calibrations for any signs of wide variances due to a dirty or broken electrode or contaminated pH buffers. During calibration, users are alerted to problems should they occur. After calibration, the electrode’s overall condition is displayed as a percentage.

GLP - Comprehensive GLP functions are directly accessible by pressing the GLP key. Calibration data, including date, time, and calibration values are stored with logged data for retrieval at a later time.

Data Logging - The log-on-demand feature allows users to store up to 200 samples that can later be transferred to a PC with the HI920015 USB cable and HI-92000 software.

Automatic Temperature Compensation - pH sensors incorporate a built-in temperature sensor in the tip of the electrode for a fast and accurate temperature compensated value.

Intuitive Keypad - The fitted rubber keypad has dedicated keys for many important and often used functions. These meters also feature two virtual soft keys that navigate the user through setup and logging of data. The interface is intuitive for any user’s level of experience.

Auto Hold - Pressing AutoEnd during measurement will automatically hold the first stable reading on the display.

Dedicated Help Key - Contextual help is always available through a dedicated “HELP” key. Clear tutorial messages and directions are available on-screen to quickly and easily guide users through setup and calibration. The help information displayed is relative to the setting/option being viewed.

Setup Screen - Our extensive setup screen features a host of configurable options such as time, date, temperature units, and language for help screens and guides.

PC Connectivity - Logged data can be transferred to a Windows compatible PC with the included HI-920015 micro USB cable and HI-92000 software.

Long Battery Life - The display of the meter has a battery icon indicator to show the remaining power. The meter uses four 1.5V AA batteries that provide up to 200 hours of battery life.

Each meter is supplied complete with sensor, calibration and cleaning solutions, beakers, PC software and connection cable, instruction manual, quick start guide, and batteries in a rugged, custom carrying case. 

About the FC10483 pH electrode

• PE sleeve
• Refillable pH electrode
• Clogging prevention system (CPS™)

The HI-98169 portable pH meter for wine uses the glass bodied FC10483 pH electrode with Hanna’s unique Clogging Prevention System (CPS^TM).

This electrode provides a fast stable response and resists clogging. The electrolyte solution in the electrode is refillable.

An integral part of any pH electrode is the reference junction. The reference junction is a part of the electrode that allows for the flow of ions located in the reference cell into the sample being measured.

The ions provide for an electrical connection between the reference electrode and the indicating electrode. A standard pH electrode will have a single ceramic junction; however, the CPS™ (Clogging Prevention System) is an innovation in electrode technology.

CPS™ technology utilises the porousness of ground glass coupled with a PE sleeve to prevent clogging of the junction. The ground glass allows proper flow of the liquid, while the PE sleeve repels dirt. As a result, pH electrodes with CPS™ stay fresh up to 20 times longer than conventional electrodes.

To optimise the flow from the electrode the refill cap should be unscrewed so that it is open. This allows for positive head pressure to be created allowing for the electrolyte to drain more easily from the reference electrode.
