GENERAL DESCRIPTION
HI 504910 acquires and transmits in a digital format to-
wards HI 504 controller, or a computer workstation, pH,
ORP and °C measurements.
The digital link allows to send additional information, espe-
cially regarding the pH, ORP and temperature probes.
MAIN FEATURES
• pH/ORP probe check.
• Pt100 or Pt1000 sensor with automatic recognition and dam-
age test.
• Setup procedure to configure general and measurement related
parameters. There are two separate sets of configuration param-
eters, one for pH and one for ORP, thus no loss of setting occurs
when changing from pH to ORP and vice versa.
• Calibration: usual pH calibration at 2 points, or quick single
point pH calibration through HI 504920 reference pH meter.
• Old probe check, dead probe check, last calibration data inter-
nally recorded: calibration date and time, pH offset, pH slope,
number of calibration points and correspondent pH values.
• Manual temperature compensation available (automati-
cally selected when a temperature input error occurs).
• Possibility of a remote connection to a computer worksta-
tion through an external modem/GSM module.
• Data logging: 6000 samples pH/°C or ORP downloadable
through RS485 and HI 92500 application software.
