Details
The HN/005221-02 is an advanced research grade benchtop pH/mV meter that is completely customizable with a large color LCD, capacitive touch keys, and USB port for computer connectivity.
The HN/005221-02 features a universal BNC connection for use with the expansive line of pH and ORP electrodes that Hanna Instruments offers.
The meter is supplied with the HN/01131B glass body, double junction, combination pH electrode that operates over a wide temperature range from 0 to 100°C.
All readings are automatically compensated for temperature variations with the separate HN/007662-T temperature probe that is included.
The HN/005221-02 can be calibrated up to five points with a choice of eight preprogrammed buffers or five custom buffers.
The HN/005221-02 features Hanna’s exclusive CAL Check to alert the user of potential problems during the pH calibration process such as “Electrode Dirty/Broken” and “Buffer Contaminated.”
The overall probe condition based on the offset and slope characteristic of the electrode is displayed as a percentage after calibration is complete.
The calibration data including date, time, buffers used, offset and slope can be accessed at any time along with the current measurement by selecting the Good Laboratory Practice (GLP) display option.
Three selectable logging modes are available: automatic, manual and AutoHold logging.
Up to 100,000 data points can be recorded in 100 lots with 50,000 records max/lot and exported to a computer for data review and storage.
