ORP2000 Extended Life ORP Sensor
Product Description
When measuring samples such as wastewaster that may contain proteins, heavy metals, or other contaminants, it is important to use an ORP sensor (REDOX sensor) designed to withstand unpredictable chemical environments. The ORP2000 features double junction reference protection, which prevents contamination by sample components that interact with silver (Ag). The durable Ultem® body ensures extensive chemical compatibility, making the ORP2000 a highly versatile analytical tool.- Virtually unbreakable with durable Ultem® body construction and recessed protected glass
- Reliable and accurate ORP / REDOX measurements
- No refilling or maintenance required with sealed gel-filled design
- Instantly ready for use and shipped in storage bottle for long shelf life – guaranteed for one year
- One year limited warranty

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

AquaSense
Swimming pools and spas use chlorine as a disinfectant and so use an analyzer to control the amount of chlorine that gets dosed. The AquaSense Swimming Pool Controller and Spa Controller measures the pool chlorine levels and the pH of the pool and then controls the chlorine and pH levels by controlling the chemical dosing. The AquaSense offers bufferless and reagentless operation and is suitable for commercial, municipal and community swimming pools.
The AquaSense has been designed to three criteria:
- Improved Safety – better sensors lead to better process control which leads to less variation in chlorine residuals even with highly variable bathing load.
- Improved Control – better process control leads to reduced chemical usage, lower costs and an improved bathing experience.
- Reduced Costs – lower chemical costs, less expensive controllers, inverter control leading to hugely reduced electrical usage costs are just a few of the ways that the AquaSense can save you money which can pay for a new controller in just a few months.
Key Benefits
- Inverter control for massive electricity and CO2 savings
- Stable and reliable residual chlorine and pH measurement and control
- Low purchase cost
- Low cost of ownership
- SMS text alarms
- Remote access via Internet
- Suitable for fresh water, salt water and outdoor pools with cyanuric acid
- Private label option for re-sellers
- Other inputs to data log and alarms
