About Us

CST Instruments Limited, established in 2012, specializes in the research and development of cutting-edge instruments for testing the compressive strength of cement and freshly mixed concrete, catering primarily to the construction and oil exploration industries.

We are proud to introduce innovative products designed to expedite the strength testing of cement and concrete, offering significant benefits to the construction sector. CST Instruments is the first company to provide dedicated instruments that save time, cost, and resources by employing a unique method and formulation to deliver near-instantaneous feedback on the compressive strength of cement and freshly mixed concrete.


Our flagship products, CemTest and ConcTest, are manufactured in the UK to the highest standards and have undergone rigorous laboratory testing and trials by respected international companies. The results from our instruments are comparable to BS EN 196-1 and BS EN 12390-3 prism and cube tests, or equivalent standards.

Thanks to the support of a UK Innovate Award, we have successfully developed and manufactured the ConcTest, a handheld scientific instrument for the accelerated testing of the compressive strength (MPa) of cement and freshly mixed concrete. This instrument robustly predicts strength (MPa) within minutes, significantly reducing the time compared to traditional methods, which can take weeks.

We recommend using our instruments in conjunction with traditional testing methods to provide accelerated assurance of the quality of cement and concrete before batching or pouring.
