pHSense

The pHSense range of online pH meters from Pi utilize the very latest and best pH sensors available in the world today for measuring the online pH of any aqueous solution. They are patented gel filled sensors with integral reference which uses no reagents, are extremely stable, and have reduced maintenance and reduced whole life costs. The junction, usually the source of error with current pH sensor technology is made from an electrochemically active solid resulting in a more robust pH sensor. Online pH meters and pH controllers are one of the most common analyzers in use today in water treatment and process plants and yet online pH meters cause continual problems for their operators. What is needed is a stable, reliable, online pH meter for a reasonable cost. That is exactly what you get with the pHSense. The pHSense sensors and flow cells are available with different controllers giving you the same great performance with different communication, display, and control options. With the pHSense range of online pH meters, you get everything that you need – and nothing that you don’t.

HaloSense Zero

Key Benefits
Many water companies want to measure free chlorine residuals without the need for chemical buffers traditionally associated with such measurements. Acetate and phosphate buffers are expensive and environmentally unfriendly. Buffer delivery systems are maintenance intensive and have fairly costly consumables and there are health and safety considerations in the handling of the acids and high disposal costs if the acid treated water is unable to be fed back into the water supply. Amperometric cells and most polarographic probes only respond to hypochlorous acid, (HOCl). HOCl dissociates into hypochlorite (OCl–) in a pH dependent manner. This is why most chlorine monitors need acid buffers in most applications. The typical pH of water measured on a water treatment works may range from 7 to 9.2. Chemical buffering reduces the pH to between 5 and 6 and ensures that the majority of the residual chlorine is present as HOCl (see graph below).
  • Low purchase cost
  • Low cost of ownership
  • Reduced pH dependency (largely pH independent)
  • Stable and reliable
  • Bufferless
  • Reagentless

pH2200 Spear Tip Plastic pH Sensor

Product Description
Looking to measure the pH of soil, meat, or cheese? A standard pH sensor with bulb shaped glass won’t effectively pierce the surface of these semi-solids; the pH glass may even crack. That’s why we’ve created the pH2200 spear tip pH sensor, specially designed to penetrate semi-solid surfaces for effective pH measurement. The sensor is assembled with a bio-friendly Ultem® body, making it safe for use in food and soil. Use this durable pH sensor at home or in the field with any pH meter accepting a BNC connector.
  • Rugged spear tip measurement surface for piercing semi-solid samples
  • Bio-friendly Ultem® body for safe measurements in food and soil
  • Long-lasting with built-in protection against protein contamination
  • No refilling or maintenance required with sealed gel-filled design
  • Instantly ready for use and shipped in storage bottle for long shelf life

UV254Sense

Key Benefits
  • UVA (ultra-violet absorbance) is an excellent surrogate parameter for TOC, DOC, COD and color.
  • UVT (ultra-violet transmission) allows for the calculation of optimal UV dose for disinfection systems, improving efficiency.
  • Accurate detection without the cost of reagents.
  • Few ongoing service or maintenance requirements.
  • Allows feed forward optimization of coagulation control, resulting in decreases in chemical consumption, reduction in sludge removal costs and minimization of DBP formation potential.
  • Strong ROI with pay back on the analyzer being seen by many customers within a few months.
  • UVA measurement ensures performance of various contaminant removal technologies such as membranes (RO, NF, UF), ion exchange (nitrates and TOC removal) and granular activated carbon (GAC).
  • Real time UVA analyzers can provide a final check of effluent water quality and can alarm an operator in case of non-compliance.
  • A UVA monitor can monitor the percentage removal of organics across any treatment system.
  • Can be combined with a CRONOS® or CRIUS® for a multi-parameter UV254 analyzer solution that suits your needs.
  • Standard Features
