Product Introduction
UHV-600 Sulfur Hexafluoride (SF₆) Gas Comprehensive Analyzer is a multi-parameter gas analyzer designed for on-site inspection of power equipment. It integrates the detection functions of key indicators such as SF₆ gas purity, dew point/moisture content, and decomposition products into one unit.
The device is mainly used for SF₆ gas-filled power equipment such as GIS gas-insulated switchgear and high-voltage switchgear. Multiple key gas parameters can be detected in a single gas sampling. Compared with using multiple independent instruments for detection, the UHV-600 can effectively reduce on-site testing steps and SF₆ gas consumption, improving the efficiency of equipment maintenance, servicing, and condition assessment.
Product Characteristics
1,Auto-calibration: sensor probe can be automatically calibrated to zero, automatically eliminate the system error caused by zero and drifting, ensuring the precision of each measurement.
2,Easy operation: large touch LCD screen, simple operation of the what you see is what you get formula.
3,Saves gas quickly: after starting the machine and entering to measuring state, dew point measurement time is about 3 min each time
4,Self-locking joint: adopt imported self-locking joint, safe, reliable and without any leakage.
5,Data storage: adopt large capacity design, can store up to 1000 groups of test data.
6,Display clear: date and parameter such as dew point, micro water (ppm), ambient temperature and humidity can be displayed directly in large 8.8 -inch high-definition touch LCD screen.
7,Built-in USB interface: can be connected directly to U disk to derived data. It will be more conveniently to analysis the data.
8,Built-in large capacity rechargeable lithium battery: a single charge can work for more than 10 hours.

Product Features
1. Real time monitoring: It can monitor the concentration, purity, humidity, decomposition products and other parameters of SF6 gas in real time, making it convenient for users to understand the gas condition at any time.
2. Data storage: Automatically store detection data for users to query and analyze.
3. Alarm function: When the detection parameters exceed the set threshold, the instrument will automatically emit an audible and visual alarm to remind the user to take corresponding measures.
4. Portable design: Adopting a portable design, it is easy for users to carry it to the site for testing.
5. Strong anti-interference ability: It has strong anti-interference ability and is suitable for various complex environments.
Application Fields
1. GIS gas-insulated switchgear testing
Used for testing the purity, dew point/moisture content, and decomposition products of SF₆ gas in GIS gas compartments. Suitable for gas condition testing during equipment commissioning, operation and maintenance, and after overhaul.
2. SF₆ high-voltage circuit breaker testing
Used for checking the quality of SF₆ gas inside circuit breakers, promptly identifying abnormalities such as moisture, contamination, or decomposition, and providing data support for equipment maintenance and safe operation.
3. SF₆ high-voltage switchgear maintenance
Suitable for routine inspection, preventive testing, fault diagnosis, and post-maintenance acceptance of SF₆ high-voltage switchgear, helping operation and maintenance personnel quickly assess equipment gas condition.
4. Substation on-site testing
Suitable for on-site testing of GIS, SF₆ circuit breakers, and other SF₆-insulated equipment in substations. The portable design allows personnel to complete multiple gas indicator tests directly on site.
5. SF₆ gas filling and post-maintenance acceptance
Used for SF₆ gas filling, replenishment, and post-maintenance testing. By testing purity, dew point/moisture content, and decomposition products, it confirms whether SF₆ gas quality meets equipment operation requirements.
Frequently Asked Questions
1.How long does it usually take to charge? When do I need to charge? When will the charging end?
The charging time varies depending on the actual remaining power, generally less than 12 hours. When the battery level indicator is low, it should be charged in a timely manner and not all the electricity should be used up to ensure the battery's service life. The charging circuit is equipped with an overcharge protection device. When the battery is fully charged, the charging indicator light will turn off.
2.How long does the instrument need to be calibrated and maintained during use?
It is generally recommended that users verify once every 2 years, and once a year in special circumstances (when there is severe air pollution).
3.Why does the SF6 gas comprehensive tester experience stagnation and data decline during the measurement process?
This is the sensor performing gain regression function, which returns to the previous testing process for verification. At this time, the interface data does not move, but the CPU is processing the data, so the data immediately drops again after a while.
4.How to protect sensors?
The built-in sensor of this instrument is protected by a probe protection room. When in operation, the protection room automatically closes through the detector, putting the instrument in measurement mode. Conversely, when the power is turned off, it automatically protects.
The UHV-600 SF₆ Gas Comprehensive Analyzer combines multiple testing functions in one compact and portable instrument, making it a practical solution for GIS, SF₆ circuit breakers, and high-voltage switchgear inspection.
