pH2400 Extended Life Glass pH Electrode
Product Description
Environmental, wastewater, and other sampling applications may expose electrodes to unknown contaminants. Over time, exposure to contaminants such as heavy metals and reactive chemicals, will take a toll on a sensor’s functional components. The best sensors for these types of applications are built to safely handle contaminants to maximize working lifetime. Our pH2400 is a glass electrode with double junction reference design to prevent fouling by sample contaminants that interact with Silver (Ag). The refillable reference junction allows users to replace the liquid fill solution as it becomes depleted or contaminated, instead of replacing the whole sensor.- Accurate measurements across full pH scale (0-14)
- Maximum chemical compatibility: glass electrode bodies are inert to most reactions
- Extended lifetime: Refillable reference junction allows sensor maintenance, saving replacement costs
- Great for wet or corrosive environments: BNC boot protects meter connection
- Compatible with any meter accepting BNC
- Instantly ready for use: Shipped in storage bottle for long shelf life – guaranteed for one year
- One year limited warranty: We stand behind all our products with the Sensorex Guarantee

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.
Key Benefits
- Stable and reliable – excellent ozone process control – ozone controllers

pH2500 Flat Surface Glass pH Electrode
Product Description
Surfaces like paper, leather, electrophoresis gels and agar plates may be difficult to measure with traditional pH glass bulbs due to concerns about breakage. A flat electrode like our pH2500, is ideally suited for these types of pH measurements as well as measurements of suspended sludges and slurries. In addition to its specially designed measurement surface, the pH2500 features double junction construction, which prevents contamination and allows testing of samples containing heavy metals or proteins.- Perfect for gels and slurries: Flat electrode measurement surface designed for testing special sample types
- Accurate measurements across full pH scale (0-14)
- Highly adaptable: Compatible with any pH meter accepting BNC
- Low maintenance: Gel-filled electrode reference design with double junction to prevent contamination
- Instantly ready for use: Shipped in storage bottle for long shelf life – guaranteed for one year
- One year limited warranty: We stand behind all our products with the Sensorex Guarantee
