AquaMetrix Series ES-1 Toroidal Conductivity Sensor, 3/4" Convertible MPT, Polypropylene Body, 15' Cable, Temperature Compensation PT1000 RTD

Item #ES1-015
  • Low maintenance - reduced cleaning requirements
  • No electrode corrosion - toroid is fully encapsulated
  • One wetted material - easier chemical compatibility
  • Wide measuring range
  • Automatic temperature compensation
The AquaMetrix Series ES-1 toroidal conductivity sensors are used in processes where conventional contacting sensors may become fouled or corroded. Each sensor comes standard with a PT1000 RTD temperature device, which provides automatic temperature compensation to 25° C (77° F).

Toroidal conductivity sensors are made up of two-wire wound toroids encapsulated in a potting compound and encased in a plastic body. One toroid acts as a transmitter and the other as a receive. An electric current is induced between the toroids through the process solution. This current is directly proportional to the conductivity of the process solution.

The Series ES-1 Toroidal Conductivity Sensor is ideal for the following applications:

  • Plating
  • High Purity Water Applications
  • Pharmaceutical Applications
  • Reverse Osmosis Systems
  • Fume Scrubbers
  • Boilers
  • Cooling Towers
  • Textile Manufacturing
  • Food & Beverage


The ES-1 provides a raw signal that requires a third party analyzer for power and signal processing. ES-1 has been compatibility verified for the following: GLI (E33, E53, E63, PRO 3), Knick (2401 Condi, 2402 Condi), Uniloc 1181T, Yokogawa (ISC402), Mettler-Toledo.
