Designed for storing and transmitting the size of a resistance unit, as well as for checking and calibration of working resistance measures and complex resistance meters with a four-pair or five-clamp connection scheme in the frequency range from DC to 10 MHz. Description: Each of the resistance measures H2-2 is a precision resistor, in series and in parallel to which fitting resistors are connected, placed in an aluminum housing. The measures have a four-pole connection scheme. Four BNC type connectors (plugs) are located on the wall of the housing. The distance between the connectors is 22 mm. In measures of 100 kOhm and 1 mOhm, it is possible to adjust the value of the time constant of the measure using a tuning capacitor.

The analyzer is designed to determine the mass fraction of sulfur from 3 million-1 (ppm) in oil and petroleum products in accordance with GOST R 51947-2002, GOST 32139-2019, GOST R EN ISO 20847-2010 / GOST ISO 20847-2014, ASTM D4294, GB/T 17040-2019. Implements an arbitration method for measuring the mass fraction of sulfur for oil, automotive fuels of class K2, K3, jet engine fuel, aviation gasoline, fuel oil and marine fuel, and is also used for operational control of sulfur content in automotive fuels of Class 4 and 5, gas oils, bitumen, lubricating oils and their components and other petroleum products. The analyzer greatly simplifies the routine analysis procedure. Intuitive interface provides convenience and ease of use. The analyzer is a proprietary development of NPO "SPEKTRON". The device is manufactured in St. Petersburg mainly from domestic components. Minimum operator actions: - calibration is selected and the name of the sample is entered; - two cuvettes are filled with a sample; - the obtained samples are placed in the analyzer and measurements are started; - all subsequent actions are performed automatically: - the average value of the mass fraction of sulfur is calculated and displayed; - repeatability is calculated; - the results are checked for compliance with the selected standard; - measurement results are printed on the built-in printer and saved.
