pH combination electrodes with liquid

electrolyte and screw plug head

For high sophisticated pH measurements in

chemical processes.

Electrolyte:

3 mol/l KCl (Type L 300), refillable

except L 6191: low temperature electrolyte

type L 200

Zero point:

pH = 7.0

Shaft diameter:

12 mm

Connection:

screw plug head coaxial

with thread Pg 13.5

The use of these electrodes is chiefly intended in

combination with the miniature pressure probe

assembly 9921/51 HD and suitable pressure hose

type 9961/09. This assembly reduces the stated

installation length by 50 mm. The side support

with screw fitting serves for application of counter

pressure.

Supply:

HD version: HD sealing type 9980/51

standard: washer 9980/52,

O-ring type 9932/07

Connecting cable:

e.g. type 9902/05 (length 5 m with free end)

For additional connecting cables, see under

Accessories.

Note:

at temperatures above 100 °C sufficient over-

pressure must counteract the boiling of the

reference electrolyte, e.g. 3.2 bar at 135 °C.

Reference electrodes are used outside the tempera-

ture application ranges stated in this catalogue

with the help of an electrolyte bridge. For applica-

tions below 0 °C, the low temperature electrolyte

L 200 or the low temperature reference electrode

9834/9 respectively must be used. For applications

above 100 °C, a sufficient overpressure must coun-

teract the boiling of the reference electrolyte, eg

3.2 bar at 135 °C. Electrodes with liquid electrolyte

render, in a corresponding pressure application, a

higher temperature employment range and

a longer life than low-maintenance electrodes.

In the case of liquid electrolyte electrodes,

a higher measuring accuracy can be expected.

Electrolyte bridges for reference electrodes

Accessory for sophisticated pH measurement in

chemical processes. An electrolyte bridge is advis-

able if the measuring solution contains strong

electrode poisons or if the electrolyte of the refer-

ence electrode reacts with the measuring solution.
