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.
Remove the instrument from the packing material and examine it
carefully to make sure that no damage has occured during shiping. If
there is any damage, notify your Dealer or the nearest Hanna Customer
Service Center.
Each instrument is supplied with:
• HI 76407/2 DO probe with 2 m (6.7') cable
• HI 76407A membrane cap (2 pcs)
• HI 7041S 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.
