HI-2221 phmeter with Calibration Check
The HI 2221 is a benchtop pH/ORP and Temperature meter that measures pH -2.00 to 16.00 range and mV in ±699.9; ± 2000 range. The accuracy is ±0.01 pH and the temperature is ±0.2 °C. The meter has a logging capability of up to 100 points.
•Up to 5 point pH calibration with 7 standard and 2 custom buffers
•Automatic temperature compensation
•Manually log up to 200 records and interval log up to 500 records
•PC compatible via USB
•Enhanced calibration messages and electrode diagnostics
GLP (Good laboratory Practice) GLP is a set of functions that allows storage and retrieval of data regarding the maintenance and status of the electrode. All data regarding pH, Rel mV, EC and NaCl is stored for the user to review when necessary.
Calibration Expiration Reminder For pH calibration, this instrument allows the user to set the number of days before the next required calibration. This value can be set from 1 to 7 days, or disabled.
Calibration data The last calibration data is stored automatically after a successful calibration.
