Hydrant capacity testing equipment series H-TEST Companies TECHPRES are devices based on many years of experience of the company BIATECH. TECHPRES equipment uses materials with even higher strength and durability. This series is addressed to companies and institutions which use the above mentioned equipment even more intensively.

H-TEST PRESTIGE is a high-class device used for servicing, checking efficiency and periodical inspections of internal hydrants DN25, DN33, DN52 and external hydrants DN80, DN100, DN150. Measurements made with the device comply with current standards and legal regulations. It cooperates with standard and glycerine filled manometers. Testing of hydrants is performed using calibrated equivalent and measuring nozzles. The H-TEST measurement technique is based on the venturi method, in which three types of venturis are used: orifices, nozzles and Venturi nozzles. This method is widely used in laboratory and industrial practice.

H-TEST PRESTIGE was developed in cooperation with the Faculty of Mechanical Engineering at the Białystok University of Technology.
