Well-designed, Inside and Out

Jenco 3177 Conductivity TDS meter front view

The Basis Series Conductivity/TDS/Salinity meter, along with the pH/mV model, forms the foundation of Jenco’s benchtop meter offerings and comes from a long line of distinguished benchtop meters, where low cost of ownership, reading quality and build quality take precedent.


Benchtop Conductivity/TDS/Salinity Meter Renowned for Accuracy and Repeatability

The reason Jenco is consistently contracted to build products for well-respected brands and the reason we can consistently win the trust of end-users is due to our reputation for being focused on reading quality. Do the right things in the right way, no cutting corners.

  • Repeatable readings with ±0.5% full scale accurate across entire measurement range
  • Uses 2-wire conductivity cells with adjustable k=0.1 or 4-wire conductivity cells k=0.475 cell constants for improved flexibility and accuracy
  • Each and every unit is hand calibrated and QC’ed by at least 2 teams
  • Simple one point calibration

Upgraded User Experience and Usability

While the Basis Series provides the quality readings you expect, it does so in a design that optimizes its user-friendliness and minimizes its footprint on your workstation.

  • Streamlined, modern and smaller design creates clutter-free workspace
  • Large, high contrast LCD
  • Convenient one point calibration
  • Automatically determines the best conductivity ranges to display readings
  • Well-situated keys with tactile feedback
  • Splash-resistant case made with durable, reinforced plastic for added protection
  • AC adaptor or battery powered

Improved Electrode Serviceability and Low Cost of Ownership

The Basis Series Conductivity/TDS/Salinity meter uses a common Jenco 8-pin DIN connector so it works with our other conductivity electrodes. The decision to make the electrode arm a detached, optional accessory further allows the Basis Series to be setup in the way that works best for you.

  • Splash-resistant case is made with durable, reinforced plastic for added protection
  • 8-pin DIN connector for conductivity cell & 10k thermistor
  • Optional, detached electrode arm
