The analyzer allows you to determine the content of sulfur and nitrogen in oil and petroleum products (diesel fuel, gasoline, kerosene, gas oil and any distillate petroleum products), hydrocarbon gas, liquefied petroleum gas (LPG), natural gas, liquefied natural gas (LNG), chemical synthesis products, biological materials by ultraviolet fluorescence and chemiluminescence. The analyzer is a proprietary development of NPO "SPEKTRON". The device is manufactured in St. Petersburg mainly from domestic components. There is a conclusion of the Ministry of Industry and Trade on the production of products in the territory of the Russian Federation. The analyzer is designed to determine: - mass fraction of sulfur in accordance with GOST ISO 20846-2016, GOST 34712-2021, GOST R 56866-2016, GOST 34237-2017, ASTM D5453-19, ASTM D6667-21, ASTM D7551-15, ISO 20729-17 ; - the mass fraction of nitrogen in accordance with ASTM D4629-17. A wide range of concentrations: from ultra-low to high. Modular principle: Each detector is a separate module. The device is equipped individually for each specific task. The possibility of simultaneous determination of sulfur and nitrogen in the analysis process. The principle of operation of the analyzer is to burn the test sample in an oxygen-enriched atmosphere or air at a temperature of 1050 ° C. The sulfur dioxide (SO2) and nitrogen oxide (NO) formed during combustion are transferred by carrier gas to the detection units with preliminary removal of water vapor, on the desiccant, and soot, on the filter. Determination of sulfur is carried out by ultraviolet fluorescence. Determination of nitrogen by chemiluminescence.

The AG-107 generator is designed to create alternating current in electrically conductive communications with the electromagnetic method of tracerouting. Features of the AG-107 generator The main distinguishing feature is the small weight and dimensions of the device with high output power. The AG-107 generator has a built-in battery based on light high-capacity lithium-iron phosphate (LiFePO4) cells with low self-discharge, dimensions 216x180x105 mm, weight 1.8 kg and provides the following maximum output parameters: The output power in continuous operation is 30 watts; output power in intermittent operation mode is 60 W; Output voltage 60 V; current 5 A. The AG-107 generator uses a control interface similar to the AG-105 generator. The generator implements: Four sine wave generation frequencies: 512 Hz, 1024 Hz, 8192 Hz and 33 kHz; continuous, pulse and dual-frequency generation modes; built-in transmitting antenna operating at frequencies of 8192 Hz and 33 kHz; the possibility of connecting an external transmitting antenna and induction tongs; built-in "multimeter" displaying, at the operator's choice, the supply voltage or output parameters: current, power, voltage, load resistance; the ability to work from an external battery or from the mains ~ 220 V. The generator can be operated from an external power supply of 10...25 V. The generator is protected from the effects of voltages up to 400 V when connected to the communication and from exceeding the permissible voltage of the external power supply. The degree of protection of the case - case IP65 completely eliminates the penetration of dust and water jets inside when the lid is open.
