701 pH/Temperature Module

SKU: 701

Add pH and temperature sensing to your 6712 or Avalanche Sampler

Plug the 701 module into your 6712 Sampler, and pl​ace the streamlined stainless steel sensor in the flow stream for accurate monitoring and logging of pH and temperature. Additionally, you can trigger the sampler to collect samples only when a specific limit is exceeded. This can be done for the entire sampling program, or you can collect separate samples of independent volumes when the parameters exceed your programmed limits.

Save time and money by sampling only when a programmed pH or temperature limit is exceeded!

Isco Samplers


  • Durable probe containing pH and temperature sensors can be mounted vertically in the flow stream, or horizontally to reduce rag-catching.

  • Exposed temperature sensor reacts and compensates more quickly to changes in flowstream temperature, providing more accurate data recorded

  • During the program’s operation, current pH and temperature values are viewable on the sampler’s LCD display.

  • All parameter data stored in the sampler is available for later retrieval, reporting, and graphing using ISCO Flowlink® software.


  • Logging pH and temperature data for wastewater streams

  • Triggering sample collection based on pH or temperature

  • Industrial monitoring

  • TMDL monitoring
