Lee Sheng-type spark leak detector SL-68AB

Sheng-li SL-68A | B-type spark leak [Function and use] Sheng-li SL-68-type spark leak detector is used to detect metal surface corrosion insulating oil and gas pipelines, cables, enamel, metal tanks, hull, etc. Construction quality layers of corrosion and aging pores, the air gap of a special detection equipment. Lee Sheng-SL-68-type microelectronic introduction of foreign high-voltage generator, computer control technology developed, in line with the national standard GB7993 and German standards DZN51163. [Features] 1, using microelectronic integrated high voltage generator, to overcome the static phenomenon; 2, with digital display, increase the output accuracy; 3, high voltage and power supply voltage can be automatically converted; 4, fast smart charger, plenty from the stop, without manual control; 5, power the Japanese original miniature switching power supply, improve performance, reduce quality; 6, at boot time, the instrument has a self-test function; 7, the instrument has anti-static, high pressure mistyped other protective systems, thereby improving the reliability of the instrument; 8. Special protection equipment, automatic adjustment to overcome the Achilles' heel of similar products; 9, line modular structure of the instrument, three anti-design, thus greatly improving the life and reliability of the instrument field use. [1] The main technical indicators measuring range: A type: 0.03-3.50mm; B Type: 3.50-10.0mm 2, the output of high pressure: A type: 0.50-15.0KV (epoxy coal tar); B Type: 15.0-36.0 KV (asphalt) 3, AC supply voltage: 220V ± 25% 4, the machine DC voltage: 68A type; 6V; 68B type: 8.4V 5, DC power consumption: <5W 6, automatic AC-DC conversion time: <0.01 7 seconds, the alarm delay: 1-2 seconds 8, host volume: 228 × 85 × 180 9, Weight: 2.5Kg (including battery) Test principle and method] metal surface of the insulating coating is too thin, iron and drain leakage resistance value and the density of the pores of the air gap is very small, and when there is high pressure passes through the spark discharge gap is formed breakdown, to the alarm circuit generates a pulse signal, the alarm audible alarm, plumbing spark tester according to this principle so as to achieve the purpose of coating leak.
