HANNA HI2400 Dissolved Oxygen Laboratory Bench Meter

HANNA HI 2400 Dissolved Oxygen Laboratory Bench Meter

• DO range up to 300%
• Altitude compensation up to 4000 m
• Salinity compensation up to 40 g/L
• Automatic temperature compensation
• Automatic calibration in air
• PC compatible via USB
• Datalogging and storage up to 8000 samples
• GLP Features

HI 2400 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 compensation based on the user settings for altitude up to 4000 m and 40 g/L for salinity.
Calibration is performed at one or two points at 0% using HANNA’s HI 7040 solution or 100% in air.

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.

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 HI 92000 software and HI 920013 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 according with the speed of DO variation inside the process.
The HI 2400 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.
