Important information for using this adapter
together with a SensoLyt armature:

Observe the following note when you want to use a
SensoLyt measuring armature with the aid of the adapter:

Warning
For safety reasons, use only electrodes especially
specified for high pressure and temperature loads (for
example pH combination electrode SensoLyt SEA-HP,
order no. 109 118). For more information, refer to the
YSI catalog or the Internet. YSI assumes no liability for
damages caused by using different electrodes.

Installation recommendations

General installation recommendations

Basic types of

installation

The optimum installation location must be individually deter­mined for the type of sensor and the application.

Influential factors

The table on the following pages contains recommendations
and the special characteristics of the individual sensors.

Flow

direction

Minimum distance: 80 mm

A

45 ° 45 °

BC

Good

 Sufficient flow of the

sensor element

A, B

 Burdening of the measuring medium with

long fibers - avoidance of them getting
caught on the sensor (rake effect)

C

 Burdening of the sample with small stones

and abrasive particles - avoidance of any
damage to the sensor element

C

 Avoidance of malfunctions of the optical

measurement (turbidity/total suspended sol­ids) by captured air bubbles and particles

A, B

 Avoidance of malfunctions of the optical

measurement (turbidity/total suspended sol­ids) by wall surfaces

B + Good flow

+ Low susceptibility to contamina-

tion

+ Low risk of membrane damage

TetraCon 700 IQ B + Good flow

+ Low susceptibility to contamina-

tion

Check and adjust cell constants
after installation (see sensor op­erating manual)

SensoLyt 700 IQ C + Good flow

+ Low susceptibility to contamina-

tion

- Danger of small stones damaging
the electrode

The enclosed fixing ring instead
of the protective hood improves
the incident flow.
Attention

: It is no protection

against small stones!

The best incident flow is
achieved when the diaphragm
points against the flow direction.

TFK 700 IQ C + Good flow

+ Low susceptibility to contamina-

tion

The enclosed fixing ring instead
of the protective hood improves
the incident flow.
