Product Overview
KTLJL High-Precision SF6 Gas Quantitative Leak Detector In addition to overcoming the shortcomings of foreign products and absorbing their advantages, this instrument also features high sensitivity, good stability, fast response speed, simple operation, and a large movement range. It can quickly and accurately perform qualitative and quantitative detection of leak points and annual leakage rates in SF6 circuit breakers and GIS..The KTLJL High-Precision SF6 Gas Quantitative Leak Detector is not only suitable for power supply departments, installation and maintenance units, and electric power test research institutes, but also suitable for SF6 high-voltage switch factories as a supporting instrument for SF6 electrical equipment and export products.
Functional Features
1. High Sensitivity: The circuit adopts optimized design to reduce noise and electromagnetic interference, thereby improving sensitivity.
2. High Accuracy: The instrument uses a verified inspection method to provide a highly accurate calibration curve, improving the credibility of SF6 leak detection results and the precision of quantitative leak detection.
3. Wide Measurement Range with Multiple Gears: The instrument can detect SF6 leakage within the leakage rate range of SF6 switchgear, with multiple gear selections and standard curves for each gear, enabling both quantitative and qualitative leak detection.
4. Intuitive Display and Audible/Visual Alarm: It uses an indicator meter for display, providing a simple and intuitive effect. When SF6 gas is present, the instrument emits an audible and visual alarm.
5. Small Size and Light Weight: Lightweight materials are used as much as possible to reduce the instrument's space and weight, greatly decreasing its volume and weight for easy transportation and portability.
6. Long Measurement Line: It can detect leak points up to about 6 meters high, with a large movement range.
7. Fast Response and Short Recovery Time: The new circuit structure speeds up the instrument's response and shortens recovery time, greatly facilitating on-site detection.
8. Built-in Self-Diagnosis Function: This instrument has the function of monitoring its own working status.
9. Long Usage Time: The usage time can reach three hours, making it very suitable for on-site use, SF6 high-voltage switch factories, and research institutes.
10. Strong Anti-Interference: The instrument adopts full shielding to eliminate external and internal interference.
11. High Stability: The instrument has high power supply voltage stability, low temperature rise, low heat loss, and good thermal stability. During the instrument's usage time, zero drift and span drift are small.
12. Good Repeatability: The instrument has good repeatability in multiple measurements.
13. High Reliability: The instrument has a reasonable circuit structure; it uses imported components with strict screening, and is also equipped with overcurrent and short-circuit protection.
