Professional Multi-Parameter
AD1020 is a professional bench meter for pH, ORP (Oxidation Reduction Potential), ISE and temperature measurements.
- Up to 5-point calibration with 7 memorized buffers (pH 1.68, 4.01, 6.86, 7.01, 9.18, 10.01 & 12.45) and two custom buffers
- Calibration time-out alarm
- pH calibration using buffers with 0.001 resolution
- pH reading with manual or automatic temperature compensation
- Log-on-demand (up to 50 samples) and automatic logging (up to 1000 samples)
- Two selectable alarm limits
- User selectable logging interval mode
- Connection to an external serial printer with the following specifications:
- at least 16 characters / line , baud rate 9600, 9-pin RS232 input
- Large easy-to-read LCD showing pH or ISE, mV and temperature readings simultaneously, together with graphic symbols
- HOLD feature to freeze the stable reading on the LCD
- GLP feature to view last calibration data for pH, ISE and relative mV
