Hanna Instruments HI7634-00 Probe for Low Range Mini TDS & Conductivity Controllers

HI7634-00 comes with 2 meters (6.6 feet) of cable attached.

The HI7634-00 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 HI7634-00 probe provides a rapid response and high accuracy EC or TDS measurement.

  • Two-pole amperometric probe
  • Internal temperature sensor
  • Low range measurement (μS/cm and ppm)

Hanna HI7634-00 Features at a Glance

  • Two-Pole Probe
    The HI7634-00 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 HI7634-00 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 HI7634-00 allows for insertion mounting into a common “T” fitting without the need for additional hardware.
