PRECISION Series pH & ORP Sensors

PRECISION Series sensors are highly accurate and durable for light-duty applications. Utilising our market-leading technology in a more compact footprint, they are economical while still retaining our superior performance characteristics. This series has a highly responsive solid-state reference combined with our tough industrial glass, making this sensor extremely effective when glass or lab-grade electrodes suffer breakages, drift or unsustainable cleaning and calibration schedules. It is an excellent sensor choice for industrial applications that don’t require the performance of the ULTRA and TOUGH Series sensors.


Customise for your process
Our PRECISION pH and ORP sensors are available with the following options that allow you to configure the sensor for your application: 

  • ¾” x ¾” MNPT, CPVC body
  • ½”x ¾” MNPT, Ryton body
  • 6m Cable length (12m  & 24m optional)
  • Temperature compensation 

About our Digital Smart Sensor (DSS) Technology
Turtle Tough gives you the option of a propriety digital signal or an open-source Modbus RTU signal that is universally accepted. To find more about the benefits of our Digital Smart Sensor technology go to turtletoughsensors.com/sensortechnology


Sensor Care and Maintenance
Turtle Tough sensors can be cleaned and calibrated offline to facilitate a hot-swapping maintenance regime. To know more about our sensor care and hot-swap maintenance regime go to turtletoughsensors.com/support/maintenance
