Polilyte plus pH sensors

Long life and high accuracy for diverse industrial pH measurements.

Polilyte Plus pH sensors are specifically designed for demanding industrial applications. They provide good longevity and stability thanks to their polymer-filled design and viscous electrolyte. The stable Polisolve electrolyte greatly slows the ingress of process chemicals, extending sensor life. Their maintenance-free design with two single pore junctions, eliminates clogging. Polilyte Plus  sensors show good accuracy in alkaline and low conductivity samples. Intelligent versions like Polilyte Plus Arc and Memosens are available for difficult processes and easy integration.

Discover Hamilton pH Glass Types

  • PHI
    Best lifespan in frequent SIP and autoclavation applications with very low drift. The PHI glass is our recommended membrane glass for bioreactor installations found in R&D, upstream and downstream pharmaceutical applications.
  • HB (Not for Memosens)
    Best lifespan in frequent CIP and autoclavation applications. Fastest response time. The HB Glass is our recommended membrane glass for food, beverage, and brewing applications.
  • HF 
    The HF membrane glass formulation is specifically recommended for use in media containing hydrofluoric acid.

  • H
    Provides stable readings in anhydrous or partially aqueous solutions. Low alkali error with good accuracy at high pH or elevated temperature. The H membrane glass works well for most general industrial applications.

Connecting to a Traditional Bioreactor?


Taking advantage of the benefits of Arc pH sensors on a traditional bioreactor requires bypassing a controller’s built-in milli-volt sensor input. The introduction of the Arc ECS Adapter simplifies this connection by utilizing the existing bioreactor milli volt input.

FAQ

What is the difference between traditional, Arc and Memosens sensors?

Traditional sensors provide standard mV output and rely on a separate transmitter or controller to amplify the signal and convert to an actual reading. Arc sensors provide a built-in microtransmitter that can output either 4 - 20mA or Modbus RTU digital communication. Finally Memosens sensors offer a digital signal that works with all Memosens transmitters and analyzers currently on the market.

FAQ

What is the effect of temperature on ORP?

Temperature compensation is a common requirement for accurate pH measurements, but not generally used for ORP. Why? pH is a measurement of the hydrogen ion concentration by the glass membrane. The voltage output of this glass membrane is temperature dependent, as is the hydrogen ion activity in the liquid. Temperature compensation will correct the pH voltage output back to a standardized 25°C. ORP differs from pH as it is not tied to a specific ion. The effects of temperature can be different depending on oxidizing and reducing substances present in the liquid. Due to this uncertainty, the ORP sensor output is uncompensated millivolts.
