pH3000 Research-Grade Plastic pH Sensor (Refillable)
Product Description
When accuracy and repeatability are critical, such as in pharmaceutical or drinking water applications, the ideal pH electrode will quickly deliver stable measurements. The pH3000 is a research grade pH meter replacement probe specially designed to respond quickly and accurately to rapid temperature changes. The high sensitivity internals also make these electrodes the best choice for low ionic samples. The double junction reference design prevents contamination, allowing pH testing in samples containing heavy metals, proteins and enzymes, or TRIS buffer.- Our most sensitive laboratory electrode: accurate to 0.04 pH in tests across full recommended temperature range
- Easily maximize measurement repeatability: Rapid renew reference system for quick refilling
- Extensive chemical compatibility: Constructed with durable Ultem®, proven in a range of chemical conditions
- Ideal for difficult sample types: Double junction reference protection for testing samples containing heavy metals, TRIS buffer, and other contaminants
- Virtually unbreakable: removable bulb guard protects pH glass and strain relief prevents damage to cable connection
- Ready for wet or corrosive environments: BNC boot protects meter connection
- Compatible with various meters: Versatile replacement probe works with any meter accepting a BNC pH probe

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

OzoSense
The OzoSense Online Dissolved Ozone Monitor from Pi for the measurement of the ozone concentration in water, is designed to be simple to install and operate, and offers unrivalled stability, accuracy and precision, whilst offering excellent value for money.
The OzoSense range of online dissolved ozone analyzers and dissolved ozone monitors utilize the very latest and best ozone sensors available in the world today. There are two sensors in the OzoSense range. The first is a membraned device which is insensitive to changing pH, uses no reagents, is extremely stable, and has reduced maintenance and reduced whole life costs. The second is a non membraned three electrode sensor, that can operate at higher temperatures and pressures.

pH2100 Flat Tip Plastic pH Electrode
Product Description
Agar plates, skin, and electrophoresis gels are all surfaces that may be difficult to measure with a typical pH glass bulb due to concerns about breakage. To facilitate these and other surface measurements, we created the pH2100 flat tip pH electrode. It has a rugged flat measurement surface, which breaks less easily when it comes in contact with hard materials. This makes it a great choice for measuring slurries, sludges, and viscous samples as well as those containing suspended solids.- Ideal for surface measurements and slurries: rugged flat measurement tip resists breakage
- Great for testing unknown sample types: double junction electrode reference design prevents contamination
- Durable and Versatile: Ultem® body offers enhanced chemical compatibility and booted BNC protects meter connection
- No maintenance required: sealed gel filled reference design
- One year limited warranty: We stand by our products with the Sensorex guarantee

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
