HI221 desktop acidity meter:
Equipped with calibration check function (Cal Check):*More calibration information: When calibrating, the instrument will display an error message to remind the user when one or more parameters are not suitable
*Display electrode status: Determine electrode status by detecting electrode zero point or slope
*Display electrode response time: Determine electrode response time by detecting electrode performance during calibration
*Calibration alarm: Programmable alarm interval can be set from 1 to 7 days
Other features:
*Data storage function, HI221 can store 100 pieces of data
*Record the last accurate time and date
*Can set the characteristic number of the instrument
*The instrument has a built-in real-time clock
*RS232 interface
