We select measurement solutions according to the environment, medium and operating requirements.
Power generation, chemicals, food production and environmental applications. Solutions focused on measurement stability and resilience in operation.
Products for industryElectrodes and probes for analytical work, research and education. Selection support for your specific sample and method.
Products for laboratoriespH, redox potential and other pool measurement equipment for public facilities and private swimming pools.
Products for poolsReproducible readings, calibration stability and fouling resistance are essential. We select the technology according to actual measurement conditions.
Increased resistance to organic and inorganic deposits helps maintain a stable, reproducible signal. The appropriate design depends on the medium and application.
THETA 90’s own manufacturing process supports fast response, reproducible readings and rapid stabilisation in unbuffered water. It also increases the resistance of the sensing elements to fouling.
In suitable process applications, recalibration intervals can typically reach one year. The actual schedule depends on the sensor, medium and operating conditions.
Galvanically isolated inputs on our industrial instruments help protect measurements against ground-loop interference.
We help select and specify a solution. Warranty and post-warranty service for our installations can also be provided as required.
THETA 90 is the Czech development and manufacturing business of Ing. Stanislav Skákal. Since 1992, it has specialised in electrochemical measurement of water and liquid media for industrial and laboratory applications.
We supply businesses of all sizes, universities, research organisations and instrumentation and control service providers. Our products are used in Czechia and abroad.
Operating instructions also include technical information, commissioning and maintenance guidance. We will provide the appropriate instructions for your model.
