Two-Pole Probe

The HI7634 is an amperometric sensor, utilizing two-pole technology to achieve accurate EC and TDS measurements. An alternating voltage is applied to the two electrodes and the generated current is measured.

Internal Temperature Sensor

The integrated temperature sensor of the HI7634 probe is crucial for accurate EC and TDS measurements. Changes in temperature of a solution will change the ion mobility, which will influence the measurement. For this reason it is important that a fast and stable temperature measurement be taken in order to provide an accurate temperature compensated EC and TDS reading.

Threaded Connection

The ½” NPT threaded connection of the HI7634 allows for insertion mounting into a common “T” fitting without the need for additional hardware.

Multiple Cable Lengths

The HI7634 is available with varying lengths of cable based on your specific requirements.

HI763-00 comes with 2 meters (6.6 feet) of cable attached.

HI7634-00/4 comes with 4 meters (13.1 feet) of cable attached.

HI7634-00/5 comes with 5 meters (16.4 feet) of cable attached.
