ULTRA Series Digital Smart pH/ORP Sensors
Array
Sensors for Ultra Tough Applications - Aggressive Media Resistant
The ULTRA Series Digital Smart pH/ORP Sensors utilise our very best materials and technologies to work in the harshest of conditions. ULTRA Series sensors have a wide variety of options that allow them to be customised for your application so you get a purpose-built sensor that will outperform all others. Customer’s who choose ULTRA Series products can work with our engineers to tailor an application-specific solution.
The UltraTough series of pH & ORP sensors are made with the very toughest materials and latest technology for exceptional performance in highly aggressive environments. Most importantly they provide accurate and stable measurements at extreme temperatures, and across a wide pH range. This range is available in 3 different body styles: fully submersible, inline sanitary or hot tap and inline twist lock, suiting a wide range of installations.

Break Resistant Glass
The UltraTough series features our unique break-resistant glass which is highly resistant to impact and high-velocity solids. Not only will the glass resist abrasion in the process, but its incredible strength means that the build-up of solids can be removed through aggressive cleaning without fear of breakage.
Solid-State Reference
At the heart of our Ultra Tough range is a Kynar solid-state reference system. Kynar has high chemical resistance, is extremely resilient to contamination and is very economical for industrial applications with temperatures up to 105°C. Our solid-state reference is formulated with specific salt mixtures, to provide extreme performance in a wide variety of applications. The non-porous attributes of this component make it extremely resistant to process contamination providing long life under harsh chemical conditions. Anti-Fouling Fouling is a common problem with most brands of sensors. Turtle Tough utilise a large open geometry design with coat resistant materials. Our ability to withstand high velocity allows the sensor to be placed in high flow areas to keep the sensor clean and maintain optimal performance of the sensor within the sensibilities of a standard cleaning regime.
Customise for your process
Our Ultra Tough sensors can be configured and customised for your application. See the product brochure for the available custom options.
