ISCO 701 pH / Temperature Module

  • Durable probe containing pH and temperature sensors Can be mounted vertically in the flow stream, or horizontally to reduce rag-catching.
  • View pH and Temperature on Auto-Sampler Display and within log.
  • Ideal for triggering sample collection based on pH or temperature
  • Ideal for logging pH and temperature data for wastewater streams
Product Options


With the 701 module plugged into the 6712 sampler, and it's stainless steel sensor in the flow stream, pH and temperature can be accurately monitored and logged. The module can be set to trigger the sampler to collect samples only when a specific, user-set parameter limit has been exceeded, which can save time and money. Alternatively the sampler can collect samples at regular intervals and be set to collect secondary, independent samples when parameter limits are exceeded.

Standard Features of the 701 Module Include:

  • Exposed temperature sensor provides more accurate data. Faster reaction to (and compensation for) flow stream temperature changes.
  • LCD display shows current pH and temperature values during operation.
  • All parameter data stored in the sampler is available for retrieval and can be used in reporting, graphing and analysis using Flowlink software.
  • PH and temperature sensors contained in a durable probe. Can be mounted horizontally to reduce rag-catching, or vertically.
