Series in 1 or 2 points at 0, 350 and 1900 mV.
• Temperature compensation of the HANNA standard buff-
ers (for pH 502 Series only).
• Temperature compensation of the pH reading (for pH 502
Series only).
• Manual temperature setting when the temperature probe is
not inserted or temperature exceeds the upper range.
• Last calibration data internally recorded (non-volatile EE-
PROM memory): calibration date and time, pH offset, pH
slopes, number of calibration points and correspondent
pH values (for pH 502 Series only) or calibration date and
time and the mV calibration points used (for mV 602 Series
only).
• Input: pH electrode with BNC connector.
• ±5 VDC output for amplified electrodes.
• Output:
