Hanna Instruments-7634-00 Conductivity/TDS Probe
The Hanna Instruments-7634-00 is a two-pole amperometric EC/TDS probe for panel mounted mini controllers that measure in the low range (μS/cm and ppm). This probe has a built-in temperature sensor for Automatic Temperature Compensation and a ½” male NPT threaded connection for insertion mounting. The Hanna Instruments-7634-00 probe provides a rapid response and high accuracy EC or TDS measurement.
Two-Pole Probe
The Hanna Instruments-7634-00 is an amperometric sensor, utilising 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 Hanna Instruments-7634-00 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 Hanna Instruments-7634-00 allows for insertion mounting into a common “T” fitting without the need for additional hardware.
Multiple Cable Lengths
The HI7634-00 is available with varying lengths of cable based on your specific requirements.
- Hanna Instruments-7634-00 comes with 2 meters (6.6 feet) of cable attached
- Hanna Instruments-7634-00/4 comes with 4 meters (13.1 feet) of cable attached
