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

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

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
