Product overview
The ISENa381 series probe is a refillable, combination sodium probe with a built-in
temperature sensor (
Figure 1 ). The ISENa38101 or ISENa38103 probe is available with a
1 or 3 m (3.28 or 9.84 ft) cable and is intended for laboratory use. The probe measures
absolute mV values in wastewater, drinking water and general applications. The probe
measures sodium concentration in water samples. A 59 mL bottle of 0.02 M NH4Cl
Electrode Filling Solution is included with the probe.
