Hanna Instruments hi 98204 User Manual

The HANNA Water Test is a "four-in-one" portable meter designed for
fast and accurate analysis and monitoring of water in biological
applications, industrial wastewater, rivers, lakes, etc. It measures the
main parameters in water analysis, namely, pH,  oxidation-reduction
potential (REDOX), conductivity and temperature.  All is needed for
the analysis is a small sample of the water which is poured into the
compartment and the 4 measurements are immediately available.
The instrument has a complete pH range from 0 to 14, an ORP range
from -1000 to +1000 mV, a conductivity range from 0 to 2000 µS/cm
and a temperature range from 0 to 60°C. The instrument can be
calibrated for pH and conductivity  and comes with replaceable batteries.

On behalf of

Hanna Instruments S.r.l.

• Separate the compartment from the tester.
• Remove deposits formed on the liquid  junction

and the pH glass bulb by  soaking in HI 7061
solution for 1½ hour.

• Soak the platinum wire in acetone for half hour.
• Rinse the bulb, platinum wire and liquid junction

thoroughly with distilled water

• Reassemble the compartment and the tester.
• Fill the compartment with tap water.

When the Water Test cannot be switched on or the
display fades, pull out the battery cover and replace
all three 1.5V batteries, while paying attention to their
polarity. Battery replacement must only take place in
a non hazardous area using the battery types speci-
fied in this instruction manual.

Before using this product, make sure that it is entirely suitable for
the environment in which it is used.
Operation of this instrument in residential area could cause
unacceptable interferences to radio and TV equipments,
requiring the operator to take all necessary steps to correct
interferences.
The glass bulb at the end of the pH electrode is sensitive to
electrostatic discharge.
Avoid touching this glass bulb at all times.
For calibration it is recommended to use an antistatic
screwdriver.
Any variation introduced by the user to the supplied equipment
may degrade the instrument's EMC performance.
To avoid electrical shock, do not use this instrument when voltages
at the measurement surface exceed 24 VAC or 60 VDC.
To avoid damages or burns, do not perform any measurement in
microwave ovens.
