  • Control parameters: Heating rate, PID settings, and communication methods are fully adjustable and locked during the test process. All parameter changes are managed via the host computer.
  • Expansion measurement range and accuracy: ±5 mm ±0.1%, ±2.5 mm ±0.1%
  • Temperature control accuracy: ±1°C, with recording errors ≤ ±0.5%. Different heating elements and control methods are used depending on the temperature range.
  • Expansion resolution: 1 µm per digit, with optional 0.1 µm per digit
  • Sample dimensions: Length: up to 50 mm or 25 mm; Diameter: 6–8 mm (maximum)
  • Test atmosphere: Vacuum (10⁻¹ mbar), static, or dynamic; inert or reactive gases available; vacuum conditions can be customized
  • Sample type: Solid or powder (with molds)
  • Sample holders: Made from quartz, alumina, or other suitable materials as required
  • Operating system: Compatible with Windows XP/98
  • Application scope: Accurately measures material expansion or contraction during heat treatment, suitable for ceramics, resins, building materials, glass, refractories, metals, and alloys

With the DP-III model, you can perform a variety of tests, including:

  • Thermal expansion coefficient measurement
  • Softening temperature determination
  • Sintering kinetics study
  • Glass transition temperature analysis
  • Phase transformation detection
  • Density change monitoring
  • Sintering rate control (RCS)

This instrument is ideal for researchers and engineers looking for precision, flexibility, and reliability in thermal analysis applications. Its combination of advanced technology and user-friendly design ensures efficient and accurate results across a wide range of materials and testing scenarios.

Garden Pot

Material: Ceramic garden pots are typically made from clay-based materials that are fired at high temperatures to achieve durability and strength. The clay used in these pots can vary in composition, texture, and color, offering a wide range of options to suit different gardening preferences and styles.
Design: Ceramic garden pots come in a plethora of designs, ranging from traditional to contemporary styles. They can feature various shapes, including round, square, rectangular, and oval, as well as unique geometric or abstract forms. The design may incorporate decorative elements such as embossed patterns, intricate reliefs, or hand-painted motifs, adding aesthetic appeal to outdoor spaces.
Size: Ceramic garden pots are available in a variety of sizes to accommodate different plants and gardening needs. They range from small pots suitable for individual herbs or flowers to large containers capable of holding shrubs, small trees, or even ornamental arrangements. The size of the pot often dictates the scale of the plants it can accommodate and the visual impact it creates in the garden.
Color: Ceramic garden pots come in an extensive array of colors, offering options to complement various plantings and outdoor design schemes. Common colors include earth tones such as terracotta, beige, brown, and gray, as well as vibrant hues like blue, green, red, and yellow. Some pots feature glazed finishes that enhance color intensity and provide a glossy or matte sheen.
Drainage Holes: Proper drainage is essential for plant health, and ceramic garden pots typically include drainage holes at the bottom to prevent waterlogging and root rot. These holes allow excess water to drain freely from the soil, ensuring adequate oxygenation and moisture balance for the plants.
Saucer or Tray: Many ceramic garden pots come with matching saucers or trays to catch excess water drainage, preventing water damage to surfaces and maintaining a neat appearance in outdoor spaces.
Insulation: Ceramic pots offer some insulation against temperature fluctuations, which can be beneficial for plants, especially in regions with extreme weather conditions. They help to regulate soil temperature, protecting plant roots from heat stress or frost damage.
Durability: Ceramic garden pots are known for their durability and longevity, making them a popular choice for outdoor gardening. When properly cared for, they can withstand exposure to sunlight, moisture, and temperature variations without fading, cracking, or deteriorating over time.
Overall, ceramic garden pots combine functionality with aesthetics, providing a stylish and practical solution for showcasing plants in outdoor landscapes, gardens, patios, and balconies. They serve as decorative focal points while providing a conducive environment for plant growth and flourishing.
