Preliminary Examination; General Description - Hanna Instruments HI2400 Instruction Manual

PRELIMINARY EXAMINATION

Remove the instrument from the packing material and examine it carefully
to make sure that no damage has occured during shipping. If there is any
damage, please contact your local Hanna Instruments Office.
Each instrument is supplied with:
• HI76407/2 DO probe with 2 m (6.7') cable
• HI76407A membrane cap (2 pcs)
• HI7041S electrolyte solution (30 ml)
• 12 VDC power adapter
• Instruction Manual
Note: Save all packing material until you are sure that the instrument
functions correctly. All defective items must be returned in their
original packing with the supplied accessories.
HI2400 is a logging microprocessor‑based DO/Temperature bench meter.
It can store up to 100 lots in memory, with up to 8000 readings.
These readings can be transferred to a computer for further analysis or
permanent storage.
Dissolved Oxygen is indicated in ppm (parts per million) or in %.
All measurements are automatically compensated for temperature.
Salinity compensation in water allows direct determination of Dissolved
Oxygen in saline waters and altitude compensation readjusts for the
altitude variance.
The Dissolved Oxygen probe has a membrane covering the polarographic
sensors and a built‑in thermistor for temperature measurements and
compensation.
This permeable PTFE membrane isolates the sensor elements from the
testing solution, but allows Oxygen to pass through. When a voltage is
applied across the sensor, oxygen that has passed through the membrane
reacts causing a current flow, and hence determining a reading.
