User Guide

HI 8033, HI 8633, HI 8733, HI 8734 and HI 933000 are some of

the most complete and versatile portable conductivity/TDS meters

ever manufactured. Designed with utmost precision and simplicity,

these meters provide for up to 3 or 4 measurement ranges. The

conductivity of a solution depends on the temperature and for this

reason measurements are carried out with reference to a standard

temperature of 25°C. If the solution measured has a different tem-

perature than 25°C, compensation must be performed.

HI 8033, HI 8633 and HI 8734 compensate for temperature manu-

ally.

HI 8733 and HI 933000, with a built-in temperature sensor and

circuitry, automatically compensate for temperature changes.

With HI 8733, the temperature coefficient is adjustable from 0 to

2.5% per degree Celsius depending on the type of solution tested.

For all the other meters the temperature coefficient is fixed at 2%.

Remove the instrument from the packing material and examine it

carefully to make sure that no damage has occurred during shipping.

If there is any noticeable damage, notify your Dealer or the nearest

Hanna office immediately.

Each meter is supplied with:

• Conductivity probe with 1m (3.3') cable

• Calibration screwdriver (except HI 8033)

• Instruction manual

• 9V battery.

Note: Save all packing materials until you are sure that the instru-

ment functions correctly. Any damaged or defective item must

be returned in its original packing materials together with the

supplied accessories.
