Accurate, Repeatable Measurements
The HI2400 is a dissolved oxygen benchtop meter with
automatic calibration and % or mg/L (ppm) measurement
range. The measurement is automatically compensated
for altitude and salinity based on the user settings for
altitude up to 4000 m and salinity up to 40 g/L.
Measurements are automatically temperature compensated by
using the polarographic DO probe with built-in temperature sensor.
This probe features screw cap membranes for easy replacement.
Calibration is performed at one or two points at 0% using Hanna’s
HI7040 solution or 100% in air.
Data Logging
With a built-in logging function, measurements are stored in non-
volatile memory, and can be transferred to a PC through the USB
port using the optional HI92000 software and HI920013 USB cable.
The software is provided with an exclusive online guide of all the
commands available and allows data printing, plotting and exporting.
The 8000 record logging interval allows the possibility of process
and experimental monitoring of DO. The logging interval is automatic
with user-selectable intervals from 5 seconds to 180 minutes.
GLP Capabilities
The HI2400 also provides users with GLP (Good Laboratory
Practice) capabilities. GLP is a set of functions that allow the
storage and retrieval of data regarding calibration. The GLP
feature provides data consistency and a calibration reminder
which can be set to alert the user that too much time has elapsed
since the last calibration and a new one should be performed.
