Sf6 Mirror Dew Point Meter Compliant With Iec 60480 Measurement Accuracy ±0.2°C Response Time 2°C/Second

SF6 Mirror Dew Point Meter Compliant With IEC 60480 Measurement Accuracy ±0.2°C Response Time 2°C/Second

Product Applications

This device is primarily used to measure the dew point (humidity) of SF6 gas in SF6 electrical equipment (such as circuit breakers and GIS combination units) to ensure equipment insulation performance and operational safety. It is also suitable for applications such as electronic component durability testing, roaster humidity control, and fuel cell testing, providing accurate data support for humidity monitoring in various fields.

Product Highlights

• Precise Measurement Principle: Supercooled mirror technology directly captures dew point temperature, eliminating the inertial error associated with traditional methods. Measurement accuracy reaches ±0.2°C, ensuring reliable SF6 gas humidity data.
• Low-Maintenance Design: The system is highly stable, eliminating the need for frequent calibration and reducing O&M costs. A built-in electronic flowmeter monitors intake status in real time to ensure consistent testing conditions.
• Flexible Adaptability: A wide range of intake flow rates (15-60 L/h) and pressures (1 kPa-1 MPa) accommodate diverse SF6 equipment testing needs. Supports dual USB/RS-232 outputs for convenient data traceability and system integration. Strong Environmental Adaptability: Semiconductor refrigeration combined with a wide ambient temperature range (0°C-50°C) allows for stable operation in high humidity environments (≤90% RH, non-condensing), with a response speed of 2°C/second.

International Reference Standard

IEC 60480:2019 "Handling of Sulfur Hexafluoride (SF6) Gas and Its Mixtures in Electrical Equipment"

Clause 5.3 specifies that SF6 gas humidity measurement must be performed using a direct method (such as the chilled mirror method). This device's supercooled mirror principle fully meets this requirement.

Clause 6.2 stipulates that SF6 gas humidity measurement accuracy must be ≤±1°C. This device's ±0.2°C accuracy exceeds this standard, ensuring data compliance.
