Our 5th generation benchtop series consists of single and multi-parameter models, with or without Bluetooth connectivity. The 6177B is a single parameter pH/ORP/temperature Based 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, data sharing, cloud data storage and user-defined compliance policies.


Renowned Accuracy and Repeatability

Repeatable, accurate results achieved with up to 5 points NIST or US buffer calibration for pH, 1 point mV offset calibration.

  • Repeatable readings with 0.01 pH and 0.1 mV resolution
  • Simple calibration with automatic buffer recognition of US and European buffers
  • Non-volatile memory holds up to 750 data points.
  • 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.
