1. Safety Information
Avoid electrical hazards:
Do not measure on or near live parts!
Preserving product safety/warranty claims:
Operate the instrument properly and according to its intended
purpose and within the parameters specified. Do not use
force.
Do not store together with solvents (e.g. acetone).
Temperature data on probes/sensors refer only to the
measurement area of the sensors. Do not expose handles and
cables to temperatures greater than 70°C if they are not
specifically designed for higher temperatures.
Open the instrument only when this is expressly described in
the documentation for maintenance purposes.
Only the maintenance and service work described in the
documentation should be carried out. Please adhere to the
steps specified. For safety reasons, only original spare parts
from Testo should be used.
Ensure correct disposal:
Disposal of defective rechargeable batteries and spent
batteries at the collection points provided.
Send the instrument directly to us at the end of its life cycle.
We will ensure that it is disposed of in an environmentally
friendly manner.
2. Intended Purpose 5
2. Intended Purpose
testo 206 is a practical instrument for spot check measurements
of pH value and temperature.
It has different applications depending on the probe/BNC module
used.
testo 206 with pH1 immersion probe
Measurement of liquid substances in the following sectors:
· Food companies (e.g. fruit juices)
· Industry (e.g. refrigerant, electroplating, chip production, paints
and varnish, print products)
· Chemistry (e.g. cleaning agents)
· Environmental protection (e.g. drinking water/waste water)
· Swimming pools, aquaria
· Agriculture
· Fish farming
· Pharmaceuticals and biotechnology
testo 206 with pH2 penetration probe
Measurement of semi-solid substances in food production and
processing: e.g. marmelades, marzipan, pastes, ready-to-serve
salad, gelling agents, fruit, milk products, bakery and
confectionery products. Laboratory measurements in companies
involved in the processing of food.
testo 206 with pH3 BNC module
The BNC socket is used to connect external pH probes. Ranges
of application depend on the probe attached.

3.3 Power
Power is via a button cell (Typ CR2032, 3V; included with
delivery).
3.4 TopSafe
TopSafe protects the instrument from
moisture and mechanical strain (impact).
We recommend you always use TopSafe.
The IP68 protection class is achieved if
the instrument is placed inside the
TopSafe and is closed.
3.5 Storage cap
The storage cap filled with electrolyte gel is
used to store the probe between
measurements.
The probe is only immediately ready to
operate if stored in electrolyte gel.
If the probe has been out of the electrolyte gel for a longer period
of time, it must be stored in the electrolyte gel for approx. 12
hours to regenerate.
The storage cap can also be attached to the wall/transport
bracket.
3.5 Wall/Transport bracket
The wall/transport bracket with belt holder
and attachment unit for the storage cap is
used for the safe storage of the
measurement instrument at a fixed point or
during transport.

5.3 Measuring
Setting up the instrument
If large quantities of the electrolyte gel are stuck to the probe
when removed from the storage cap, it is a sign that the gel is
spent.
A new storage cap is needed.
Clean off the pH probe before and after each measurement
with low concentration soap water followed by tap water
(water temperature should be below 40°C). Dab dry with a
paper towel. Do not rub.
When using the BNC module, please note the application
information included with the external probe.
1Carefully remove storage cap.
2Switch on instrument: .
Carry out measurement
Measurement tip made of glass, risk of breakage!
Risk of injury on account of glass parts which remain in the
measurement medium.
Check measurement tip of pH probe after each
measurement for damage.
Immerse/penetrate probe in the medium to be measured.
- The measured pH and temperature values are displayed. The
readings are updated twice a second.
Hold readings manually: .
Restart measurement: .
- If Auto-Hold is switched on, AUTO HOLD flashes until the
instrument has found a stable pH reading. The readings are
then frozen (AUTO HOLD lights up). If no stable pH readings
have been found within 300s, the measurement is stopped
( and AUTO HOLD light up).
Restart measurement: .
