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 IN PLUS is a high class device used for servicing, checking efficiency and periodical inspections of internal hydrants DN25, DN33, DN52. Measurements made with the device comply with current standards and legal regulations. It cooperates with standard and glycerine filled manometers. Tests of hydrants are carried out 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 IN PLUS was developed in cooperation with the Faculty of Mechanical Engineering at the Białystok University of Technology.
