Our 5th generation benchtop series consists of single and multi-parameter models, with
or without Bluetooth connectivity. The 3177B is a single parameter conductivity / salinity /
TDS / temperature Bluetooth benchtop meter that pairs with iOS and Android tablets to
enable the same user experience as users’ favorite apps while providing graphing, guided
calibration procedures, GLP-compliant data storage, data sharing, cloud data storage and
user-defined compliance policies.


Renowned Accuracy and Repeatability

Repeatable, accurate results achieved with conductivity calibration points in multiple ranges.

  • Each and every unit is hand calibrated and QC’ed by at least 2 teams
  • CE, FCC ID, RoHS complaint

App-Enhanced Productivity

Free iOS and Android apps are as easy and convenient to use as users’ favorite apps, and allow complete control of all on-meter functionality plus guided calibration procedures and much more.


Great User Experience

Streamlined and modern design is paired with a large, high contrast backlit LCD, buttons with tactile and audio feedback, and a detached electrode holder arm.

  • Streamlined, modern and smaller design creates clutter-free workspace
  • Large, high contrast LCD
  • Well-situated keys with tactile feedback
  • AC adaptor or battery powered
  • Splash-resistant case made with durable, reinforced plastic for added protection

Improved Electrode Serviceability and Low Cost of Ownership

Standard 8-pin DIN for conductivity and temperature electrodes.


Easily Share Data Locally or to the Cloud

Share stored data to other apps such as Notes and Evernote or to cloud services such as Google Docs.


High Information Availability

Display conductivity, salinity or TDS with temperature readings simultaneously with last calibration date and real-time graphing.


GLP-Compliant Data Storage

Greater than10k Sets of conductivity, salinity, TDS and temperature data plus calibration data such as calibration date, buffers used, calibration slopes and calibration offsets.
