NPP TECHNOPRIBOR is a leading Russian enterprise that has developed and mastered the serial production of the most complete set of stationary and portable measuring devices for monitoring the physical and chemical parameters of liquids. Based on our own production equipment we offer innovative automatic chemical control systems, including a full range of services from design and production to installation and further maintenance at the Customer's facility. The systems use multichannel multiparameter transmitters capable of simultaneously working with different types of measuring units, which makes the system much more compact and easier to maintain. For the first time in the industry, it is possible to order sample preparation devices (SCPs) taking into account any specific technical requirements of the Customer, including using unique solutions based on Pelte elements.We have developed unique laboratory instruments: a line of Russian exclusive photometric counting analyzers of mechanical impurities GRAN - 152 and GRAN 152.1 with built-in auto-calibration device and sensitivity adjustment for working with various, including aggressive liquids; a series of portable multichannel analyzers LIDER -600 with the ability to quickly and accurately measure (pH, pNa/pX, O2,H2,t) in a stream or in a separate container for applications ranging from sample control in the laboratory to scientific research. All devices are verified in their own accredited laboratory, have certificates and are included in the Russian State Register of Register of Measuring Equipment.
