SUNPASS Launches 4-inch DN100 Capillary Filled Oil Thermometer, Empowering Safe Temperature Measurement for Tank Container Storage and Transportation

Founded in 1979, SUNPASS is one of the earliest sealing products manufacturers in China. It has a 12,000 ㎡ modern professional workshop and more than 20 standardized production lines. The company has passed TUV/SGS ISO9001 quality management system certification and is a member of ITCO (International Tank Container Organization). Its products are exported to more than 100 countries and regions, and it has long provided OEM/ODM services for internationally renowned sealing brands, accumulating profound technology and reputation in tank container storage and transportation, oil and gas, chemical and other industries.

The 4-inch DN100 Capillary Filled Oil Industrial Thermometer released this time is a special temperature measuring instrument developed by SUNPASS based on the extreme working conditions of the tank container industry, with outstanding core highlights:

1. Robust Materials for Extreme Environments

The case, flange and capillary sheath are made of 304 stainless steel, which is salt spray and corrosion resistant, suitable for harsh working conditions such as maritime transportation and chemical industry; the brass precision movement has stable heat conduction and smooth transmission, paired with food-grade glycerin filling design, providing strong shock resistance, suppressing pointer jitter and greatly extending product service life.

2. Precision Technology for Accurate and Stable Temperature Measurement

Adopting CNC integrated molding process with dimensional tolerance ≤±0.02mm; each product is calibrated at multiple points across the full range, with industrial 1.5-level accuracy; dual sealing + helium mass spectrometry leak detection process eliminates medium leakage, suitable for pressure and high and low temperature working conditions.

3. Full-dimensional Compliance for Global Access

In line with global general standards for tank container industry, SGS material inspection reports and factory qualification certificates are available, adapting to market access requirements of IMDG, EU, North America and other regions, with no trade barriers for export.

4. Flexible Customization and Efficient Delivery

Support personalized customization of temperature measurement range, capillary length (1M/2M/3M and custom), scale marking and installation method; relying on sufficient inventory and large-scale production capacity, regular spot goods are delivered within 48 hours, and bulk orders are delivered stably.

This product can be widely used in tank container storage and transportation, petroleum and natural gas, chemical and pharmaceutical, ocean-going ships, electric power and paper making, food cold chain and other fields, accurately meeting the temperature monitoring needs of hazardous chemical storage and transportation and industrial production processes. It is matched with SUNPASS sealing parts and thermal insulation products to reduce costs and increase efficiency for customers.

In the future, SUNPASS will continue to take "Revitalizing the Enterprise through Science and Technology, Inheriting for a Century" as its vision, deeply cultivate the sealing and measurement and control field, continuously iterate products and solutions, and provide more professional, safer and more efficient products to become the preferred partner for sealing systems in global key industrial sectors, helping Chinese industrial brands go global.
