ASTM S5C Non-Mercury Thermometer, -38 to 50C, NIST

Introducing the ASTM S5C Non-Mercury Thermometer, a high-precision instrument designed for accurate temperature measurement from -38°C to 50°C. This thermometer provides a safe, reliable, and eco-friendly alternative to traditional mercury thermometers without sacrificing performance.

This liquid-in-glass thermometer utilizes a specially formulated, biodegradable, non-toxic, and non-hazardous blue liquid. The deep blue color of the indicating fluid offers excellent contrast against the white-backed stem, ensuring clear and easy readings every time. Engineered for durability and precision, it delivers the same performance characteristics you expect from ASTM Mercury Thermometers.

Each thermometer is individually serialized and includes a NIST Traceable Certificate of Calibration from an ISO/IEC 17025 accredited laboratory. This certification guarantees that the thermometer has been meticulously calibrated against recognized standards, ensuring the highest level of accuracy and quality control. The five-point calibration is conducted via direct comparison in a high-stability liquid bath using a Precision Reference Thermometer (PRT) and Standard Platinum Resistance Thermometer (SPRT). Before testing, each unit is rigorously inspected for any physical defects, such as cracks or liquid-column separations, to ensure its integrity.

Key Features:

• Compliance: Fully meets the stringent requirements of ASTM E1, E77, and E2251 standards.
• Safe Indicating Fluid: The proprietary blue liquid is non-hazardous, non-toxic, and biodegradable, making it a responsible choice for any lab.
• High Visibility: The dark blue fluid is easily readable against the white-backed stem, reducing reading errors.
• Certified Accuracy: Comes with a NIST Traceable Certificate of Calibration, providing assurance of its precision.
• Specific Applications: Ideal for specialized tests, including Saybolt Viscosity and Cloud & Pour point determinations.

Specifications:

• ASTM Number: S5C
• Temperature Range: -38°C to 50°C
• Divisions: 1°C
• Immersion Depth: 108mm (4.3in)
• Type: Non-Mercury, Liquid-in-Glass

Proper Care and Use: To maintain the integrity of the thermometer and prevent fluid column separation, it is crucial to store it vertically. Using a dedicated thermometer storage rack is highly recommended. For applications in ovens or other exposed environments, a thermometer well can provide essential protection and thermal stabilization, extending the life and accuracy of the instrument.
