KS-30CSR
The KS-30CSR SF6 Gas Analyzer is a professional portable instrument designed for accurate measurement of SF6 gas purity and dew point in high-voltage electrical equipment.
SF6 gas is widely used as an insulating medium in gas-insulated switchgear (GIS), circuit breakers, and substations. The gas quality directly affects the insulation performance and operational safety of electrical equipment. Moisture contamination or reduced gas purity can significantly decrease insulation strength and lead to partial discharge or equipment failure.
The KS-30CSR analyzer integrates SF6 purity measurement, dew point detection, pressure monitoring, and gas pump-back recovery in one portable device. Using advanced constant-temperature and adiabatic chamber technology, the instrument reduces the influence of ambient temperature and humidity, ensuring highly stable and accurate measurement results.
The device is designed for field testing and maintenance, allowing engineers to quickly analyze SF6 gas quality inside GIS equipment without releasing gas into the atmosphere. The built-in pump-back system returns the sampled gas back to the equipment after testing, preventing gas loss and supporting environmentally responsible maintenance operations.
Because of its high accuracy, portability, and integrated functions, the KS-30CSR analyzer is widely used by power utilities, switchgear manufacturers, electrical service companies, and high-voltage equipment maintenance teams.
The analyzer measures dew point in the range of -80°C to +20°C, enabling precise detection of moisture contamination in SF6 gas systems. Maintaining proper dew point levels is critical for ensuring insulation reliability in GIS equipment.
The device measures SF6 gas purity from 0% to 100% with an accuracy of ±0.1%. This ensures that the insulating gas inside electrical equipment meets required technical standards.
The KS-30CSR analyzer includes a gas recovery function that pumps the sampled gas back into the equipment after testing. This feature prevents unnecessary SF6 emissions and reduces gas consumption during maintenance.
The internal constant-temperature and adiabatic design minimizes environmental influence, ensuring consistent measurement accuracy even in challenging field conditions.
With a compact structure and durable design, the analyzer is suitable for substation testing, GIS maintenance, and on-site inspections.
The instrument can store up to 200 measurement records and export data via USB for reporting and documentation.
The KS-30CSR SF6 gas analyzer is widely used in the power industry and related sectors.
Engineers can quickly measure SF6 gas purity and moisture inside gas-insulated switchgear to ensure the equipment operates within safe parameters.
The analyzer helps maintenance personnel verify gas quality inside SF6 circuit breakers during inspection and servicing.
Routine substation inspections require periodic SF6 gas testing to ensure proper insulation performance.
Switchgear manufacturers use SF6 gas analyzers during factory testing to ensure equipment is filled with high-quality insulating gas before delivery.
Maintenance companies performing field testing and diagnostics rely on portable gas analyzers for efficient service operations.

The KS-30CSR analyzer performs SF6 gas analysis through a combination of advanced sensing technologies.
First, the instrument extracts a small gas sample from the equipment using a controlled flow system. The gas then enters the measurement chamber where specialized sensors analyze the gas composition.
The dew point sensor measures moisture content by detecting the temperature at which condensation occurs. Meanwhile, the SF6 purity sensor determines the concentration of SF6 gas relative to other gases present in the sample.
The analyzer also measures gas pressure to ensure proper sampling conditions. After the measurement process is completed, the built-in pump-back system returns the sampled gas to the equipment, minimizing environmental impact.
This integrated measurement process allows engineers to quickly determine whether the gas quality meets operational standards.
