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
