ASTM S120C Thermometer 38.5 to 41.5C, NIST Calibration

ASTM S120C Non-Mercury Thermometer (38.5 to 41.5°C) with NIST Calibration

The ASTM S120C Non-Mercury Thermometer is a precision instrument designed for applications requiring accurate temperature measurements, such as kinematic viscosity testing. With a measurement range of 38.5 to 41.5°C and a fine graduation of 0.05°C, this thermometer offers exceptional performance for specialized laboratory needs. Its total immersion design ensures accurate readings when fully submerged.

Key Features:

• Compliance with Industry Standards: Meets ASTM E1, E77, and E2251 requirements, ensuring reliability and accuracy for laboratory applications.
• Non-Hazardous Design: Uses a safe, biodegradable, and non-toxic blue liquid instead of mercury, making it an environmentally friendly alternative.
• High Visibility: The dark blue fluid is easy to read against the white-backed stem, minimizing errors during use.
• Durable Construction: Inspected for cracks and fluid column separations to ensure long-term reliability.

Calibration and Certification:

The thermometer comes with a NIST Traceable Certificate of Calibration, providing a five-point calibration performed in an ISO/IEC-accredited laboratory. The calibration process uses a high-stability liquid bath with a Precision Reference Thermometer (PRT) and a Standard Platinum Resistance Thermometer (SPRT) to ensure the highest level of accuracy. Each thermometer is inspected for defects and calibrated at five temperature points for consistent performance.

Specifications:

• ASTM Number: S120C
• Temperature Range: 38.5 to 41.5°C
• Immersion Type: Total
• Application: Kinematic viscosity testing and other compatible laboratory uses
• Graduations: 0.05°C
• Length: 12.0 in (305 mm)
• Type: Non-mercury liquid-in-glass

Additional Considerations:

• Storage: To prevent fluid column separation, always store the thermometer vertically in a proper storage rack.
• Thermometer Well Compatibility: For enhanced thermal stabilization and protection, especially in ovens or exposed environments, use a compatible thermometer well.

Applications Beyond Kinematic Viscosity Testing:

While primarily specified for kinematic viscosity testing, this thermometer is versatile and suitable for other applications requiring precise temperature measurements within its range, such as quality control, research, and industrial processes.

Make the switch to a safer, more environmentally friendly thermometer without compromising on precision. The ASTM S120C Non-Mercury Thermometer is the ideal choice for professionals seeking reliability and compliance in their laboratory tools.
