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 meas-
urement area of the sensors. Do not expose handles and
cables to temperatures greater than 70°C if they are not spe-
cifically 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 docu-
mentation should be carried out. Please adhere to the steps
specified. For safety reasons, only original spare parts from

We will ensure that it is disposed of in an environmentally
friendly manner.
2. Intended Purpose
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
