With HI9625 and HI96250 you can also mea-
sure ORP (Oxidation Reduction Potential) or
Ion Specific (ISE). mV measurements auto-
matically switch from 0.1 to 1 mV resolution
when the reading reaches 400 mV.
All pH measurements are automatically com-
pensated for temperature changes (ATC) when
used with the supplied temperature probe.
It is possible to connect the HI96240 and
HI96250 to a PC through the RS232C serial
port for monitoring data via computer.
Other features include:
• automatic pH calibration (1, 2 or 3 points)
• 5 memorized pH buffers: pH 4.01
6.86
7.01
9.18

• dual level display with graphic symbols,
including defective electrode indication
• 24 hr clock with date and time.
• 12VDC socket for external power supply
• low battery detection.
Made of tough, lightweight ABS material, the
water-resistant rugged casing are built to last.
These heavy-duty pH meters comply with the
IP67 standards: dust-tight, they are protected
against the effects of temporary immersion in
water and are designed to provide laboratory
results and accuracy under harsh industrial
conditions.
