SP-700 Water Multimeter

The Pyxis SP-700 handheld multimeter measures six key water treatment parameters simultaneously: pH, conductivity, PTSA, fluorescein, ORP, and temperature. Featuring simple, one-handed operation, the multimeter leverages Pyxis proprietary technology combining electrochemical and optical measurements in a cuvette-less platform.

With the SP-700, you can view results in under a minute for all key parameters for a typical water treatment application such as cooling tower analysis. The multimeter logs a complete measurement history, which you can transfer via Bluetooth to your smart phone or PC for statistical analysis.

Custom product names and tracer/product ratios can be configured via Bluetooth-enabled devices.

For highest accuracy, the PTSA measurement uses our proprietary signal processing algorithms to compensate for sample color and turbidity conditions, which would otherwise cause erroneous readings.

SP-700 Features

  • Breakthrough technology combines PTSA / fluorescein with conductivity / pH and ORP in a single, rugged one-handed meter.
  • Proprietary pH / ORP module design with extra-large junction capacity provides increased service life and can be replaced without opening the meter enclosure.
  • Intelligent sensor aging and pollution detection capability provides self-diagnosis during calibration.
  • On-board storage lets you record up to 8 Gb of historical data with time stamp and options to set up sample location information.
  • Long battery life enables 10,000+ readings.
