User Guide

HI 9033, HI 9034, HI 9039, HI 9130, HI 933100 and HI 9635 are

multirange conductivity/TDS meters with Automatic Temperature Com-

pensation. These meters utilize the latest in four-ring potentiometric

technology which has been proven to provide higher accuracy than

the common amperometric method.

HI 9033, HI 9130, HI 933100 and HI 9635 have a range of 0 to

199900 µS/cm (µmho/cm); HI 9034 has a range of 0 to

19990 mg/L (ppm). HI 9635 can also take TDS measurements in

the 0 to 100,000 mg/L range, and temperature measurements in

the 0.0 to 60.0°C range. Thanks to this wide measurement range,

these meters can be used to analyze any sample from deionized

water to brine.

In particular, HI 9130 with its white casing and easy operation has

been specifically designed for the food industry.

HI 9039 can measure conductivity, temperature and two different

types of fertilizer concentrations (F1 and F2) for applications in

agriculture and horticulture. To measure the fertilizer content, simply

standardize the two different fertilizer ranges. To monitor the quality

of the water used with the fertilizer, the conductivity must be checked.

This also helps in the selection of water to be mixed with the fertilizer.

The temperature of all conductivity/TDS measurements is automati-

Remove the instrument from the packing material and examine it to

make sure that no damage has occurred during shipping. If there is

any damage, notify your Dealer.

Each meter is supplied complete with:

• HI 76302W Conductivity Probe with 1 m (3.3') screened cable

•9 V battery (except HI 933100 and HI 9635 which are

supplied with 4 x 1.5V AA)

•Soft carrying case (HI 9130 only)

•Hard carrying case (except for HI 9130)

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

instrument functions correctly. Any defective item must be

returned in the original package together with the supplied

accessories.
