Application Questionnaire

At Turtle Tough we custom build our systems to meet the world's most demanding industrial liquid-analysis applications. Tell us about yours and we'll send you the most detailed and relevant information possible.

The more detail you give, the better we can match the chemistry and physical demands of your application. If you're unsure about a question, say so — it's your responsibility to confirm the chosen product suits your requirements. We match specifications in good faith; some trial and error is expected with tough applications.

How would you like to start?

Pick one — all three reach our application engineers the same way.

You've come to the right place. Turtle Tough sensors provide extremely stable and reliable measurement in difficult applications. Compared to mainstream brands you should experience less drift and therefore much tighter process control which can results in significantly reduced operating costs and improved recovery. Please let us know more about your application so we can help.

You've come to the right place. Turtle Tough sensors have a number of unique design and material technologies that greatly improve reliability. Our solid-state reference system is one of our market leading technologies and provides unparalleled performance against poisoning and fouling. The massive surface area of this component means it takes much longer to foul or become compromised meaning longer intervals between cleaning and calibration. Our unique glass formulations are all designed to be extremely resilient for the intended application. The result of these carefully selected sensing elements means that you can also deploy an extremely effective cleaning regime. Harsh chemicals can be used to effectively strip the sensor of contaminants without damaging it. This is a major advantage in returning highly contaminated sensors to a fully operable state; something which most major brands are unable to achieve. Please let us know more about your application so we can help.

You've come to the right place. Turtle Tough sensors have several unique design and material technologies that can greatly reduce maintenance requirements. Our solid-state reference system is one of our market leading technologies and provides unparalleled performance against poisoning and fouling, thereby increasing the stability and reliability of the sensor over time. As the reference is much slower to respond to poisoning the stability and reliability increase considerably. It can be exposed to extremely harsh cleaning chemicals without compromising the sensors performance. The massive surface area of this component means it takes much longer to deteriorate or become compromised meaning less drift between cleaning and calibration. Our unique glass formulations are all designed to be extremely resilient for the intended application; the result being much less drift and more stable measurement between calibrations. Please let us know more about your application so we can help.

Thanks for your interest in our product. Our ULTRA series sensors represent the very best of our sensor technologies and we recommend you investigate those first.

A member of our team will be in contact shortly, to provide you with further information.

If you are looking for a cheaper sensor, then we recommend you seek out the mainstream brands. People usually come to us when they are having a particular challenge using mass produced commercial sensors. Our sensors are individually hand-made and are quite a bit more expensive than your average sensor, however they are able to overcome a specific challenge or deficiency in the existing measurement scenario, and therefore the cost typically justifies the benefit. For difficult applications, the long term cost of ownership is less when using a Turtle Tough Sensor, as the serviceability will prove more economical than low cost sensors. If your application does not present any major challenges and your existing sensor is lasting more than 12 months, then we recommend you stay with your existing product.

If you would like to know more about our pricing, please see our price guide:

TurtleTough Sensors pricing

At Turtle Tough our objective is to provide you with the lowest cost of ownership. That does not mean the cheapest sensor, but instead a sensor that lasts considerably longer than a low cost sensor and presents less challenges in meeting the application requirements. A quality sensor designed for the intended tasks will provided greater accuracy with less manpower, resulting in considerably reduced costs to the overall cost of ownership. If you would like to learn more about what we can do on that basis, please continue with our quote form.
