ASTM S116C Thermometer 18.9 to 25.1C, NIST Calibration

ASTM S116C Enviro-Safe Non-Mercury Thermometer, 18.9 to 25.1C, with NIST Traceable Calibration

This precision liquid-in-glass thermometer offers a safe, accurate, and environmentally friendly alternative to traditional mercury thermometers. It is designed to meet the rigorous demands of laboratory and industrial applications, providing reliable temperature readings within a specific range.

Key Features:

• Mercury-Free and Safe: This thermometer uses a proprietary, biodegradable Enviro-Safe® blue indicating liquid. This non-toxic and non-hazardous fluid eliminates the safety risks and disposal challenges associated with mercury, making it a responsible choice for any setting.
• High Visibility: The dark blue liquid stands out clearly against the white-backed stem, ensuring easy and accurate readings, reducing the potential for parallax error.
• Identical to ASTM Standards: While not yet officially adopted by ASTM for this specific application, its physical and performance characteristics are identical to ASTM mercury thermometers, ensuring a seamless transition in your established testing procedures.

NIST Traceable Certificate of Calibration:

Each thermometer includes a comprehensive NIST Traceable Certificate of Calibration, providing independent verification of its accuracy. This five-point calibration is performed in an ISO/IEC 17025 accredited laboratory, guaranteeing the highest level of quality assurance. The process involves:

• Direct comparison against a high-precision Standard Platinum Resistance Thermometer (SPRT) in a high-stability liquid bath.
• Thorough inspection for any physical defects, cracks, or liquid column separations prior to testing.
• Accurate measurements are recorded at five distinct temperature points across the thermometer's range.

This certificate ensures your measurements are reliable and your quality control standards are met.

Specifications:

• ASTM Number: S116C
• Temperature Range: 18.9° to 25.1°C
• Division: 0.01°C
• Application: Tag Closed Low flash point testing
• Immersion: Total
• Type: Non-Mercury, Enviro-Safe® Liquid-in-Glass
• Length: 24in (614mm)

Storage and Handling:

To maintain the integrity of the thermometer and prevent fluid column separation, always store it vertically in a dedicated storage rack when not in use.

Optional Accessory:

• Thermometer Well: For added protection and thermal stabilization, consider using a thermometer well, especially when using the thermometer in ovens, incubators, or other exposed environments. This accessory helps shield the glass from accidental impact and provides a more stable temperature reading.
