If there is any damage, notify your Dealer.
Each meter is supplied complete with:
• HI 76309 Conductivity/TDS probe
• AA size Alkaline Batteries (4 pcs)
• Instruction manual
• Rugged Carrying Case.
Note: Save all packing material until you are sure that the instrument
functions correctly. Any defective item must be returned in its
original packaging together with the supplied accessories.
HI 9835 is a waterproof portable microprocessor-based Conductivity/
TDS/NaCl/temperature meter.
The autoranging feature of the EC and TDS ranges automatically sets
the meter to the scale with the highest possible resolution.
The measurements are automatically (ATC) or manually (MTC) compen-
sated for temperature. The temperature coefficient value is user
selectable. It is possible to disable the temperature compensation and
measure the actual conductivity.
The meter is equipped with a stability indicator.
The Battery Error Preventing System (BEPS) switches the meter off
when the batteries are too weak to support proper function.
