Enhanced Measurement Assurance
Beyond its specialized meat pH electrode, the HI98163 incorporates Hanna's CAL Check™ system, which proactively alerts users to potential calibration issues. This is particularly valuable in meat processing environments where probe contamination from food solids is common and can lead to measurement inaccuracies. By comparing current calibration data with previous values, the meter provides on-screen prompts indicating the need for probe cleaning, replacement, or potential buffer contamination. Post-calibration, an intuitive probe condition indicator is displayed as a percentage (0-100% in 10% increments), reflecting the overall health of the pH electrode based on its offset and slope characteristics, both of which are accessible in the GLP data.
In measurement mode, a simple press of the "AutoHold" virtual key freezes a stable reading, automatically logging the data. An optional "out of calibration range" warning can be activated to notify users if a current measurement falls outside the calibrated pH values, ensuring data integrity.
The log-on-demand feature allows for the storage of up to 200 samples. This logged data, along with comprehensive Good Laboratory Practice (GLP) information, can be easily recalled or transferred to a PC using Hanna's HI920015 micro USB cable and HI92000 software, facilitating traceability for specific product batches. GLP data includes critical information such as date, time, calibration buffers, offset, and slope, readily accessible via a dedicated GLP key.
A context-sensitive help menu, providing information relevant to the current screen, is accessible at any time with the press of a dedicated button.
The high-contrast graphic LCD screen ensures excellent visibility in both bright outdoor and dimly lit indoor conditions, enhanced by a user-adjustable backlight. The combination of dedicated and virtual keys offers intuitive operation with multiple language options.
The compact and durable HI720161 carrying case is custom-molded to securely house all components necessary for on-site measurements, including the meter, electrode, beakers, buffer solutions, and cleaning solutions, ensuring organized and protected portability.
