Standard
EPHS, EPHM and EPHL: BNC connection and 0.8, 4.5 or 15 m cable.
Measuring electrodes
pH electrodes
Combination electrodes for measuring pH in water with a pH between 0 and 14, including low-conductivity water: for swimming pools, drinking water, wastewater and industrial water.
- Range 0 – 14 pH
- Also for low-conductivity water
- BNC or SN6 connection
- In by-pass, in-line or immersion

Models
Available models
All models are combination electrodes with an epoxy body (glass for the high-temperature model). They differ in cable, connection and application.
Insight: how pH is measured →SN6 connection
EPHSN6: SN6 connection with PG13.5 thread and cable from 1 to 100 m.
Double junction
EPHM/D (BNC) and EPHM/D/SN6 (SN6); EPHMD/100 for temperatures up to 100 °C.
Low conductivity
EPHMD/LI: for water with a minimum conductivity of 3 µS.
Self-cleaning
EPHSC (BNC) and EPHSC/SN6 (SN6), double junction.
Hydrofluoric acid
EPHM/HF: resistant to 1% hydrofluoric acid.
High temperature
EPHSN6 GK: glass body, from −5 to 135 °C and up to 10 bar.

Installation
Installation
The probe is installed in one of the Giemme probe holders:
In by-pass
In a flow-through probe holder, installed in by-pass on the pipe.
Probe holders →In-line
In a probe holder mounted directly on the pipe.
Probe holders →Immersion
In an immersion probe holder, directly in the tank or basin.
Probe holders →Advice on selection
Tell us the characteristics of the water to be measured and of the system: we will recommend the most suitable electrode, probe holder and controller.
