• Separate the compartment from the tester.
• Remove deposits formed on the liquid junction
and pH glass bulb by soaking in HI 7061 cleaning
solution for 30 minutes.
• Soak the platinum wire in acetone for 30 minutes.
• Rinse glass bulb, platinum wire and liquid junc-
tion thoroughly with distilled water
• Re-assemble 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 safe area and using the battery types specified in
this instruction manual.

Recommendations for Users
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
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

The Water Test is a "four-in-one" portable meter designed for quick
and reliable measurement of the four most important variables in
water analysis: pH, ORP, conductivity and temperature.
Water Test is engineered with great simplicity, that even non-techni-
cal personnel can use it: just fill the base with the sample to be
measured, press the RANGE key to select the mode and read the
Water Test is perfect for use in the fields of water treatment analysis,
wastewater test, ecological studies, aquaculture and hydroponic ap-
