ASTM S12C Non-Mercury Thermometer, -20 to 120C, NIST

ASTM S12C Non-Mercury Thermometer: Precision, Safety, and NIST Traceability (-20 to 120°C)

Elevate your laboratory's accuracy and safety with the ASTM S12C Non-Mercury Thermometer. Designed for precision measurement across a wide range of applications, this thermometer offers exceptional performance from -20°C to 120°C, with fine 0.2°C graduations. Its total immersion design is specifically suited for critical tests like gravity testing, ensuring optimal accuracy by fully submerging the indicating liquid column in the substance being measured. With a total length of 16.7 inches (425mm), it provides clear readability and robust handling.

Safe & Reliable Non-Mercury Technology: Moving beyond traditional mercury thermometers, the ASTM S12C utilizes a proprietary, biodegradable, non-toxic, and non-hazardous blue indicating fluid. This advanced formulation not only eliminates the risks associated with mercury exposure but also delivers the same high-performance characteristics as its mercury counterparts. The vibrant dark blue fluid stands out sharply against the white-backed stem, making readings quick and error-free, even in demanding laboratory environments.

Key Features for Uncompromising Quality:

• ASTM Compliance: Meets rigorous ASTM E1, E77, and E2251 requirements, guaranteeing adherence to industry standards for quality and performance.
• Environmentally Responsible: Features a non-hazardous, biodegradable indicating fluid, aligning with modern safety and environmental protocols.
• Superior Readability: The dark blue fluid provides high contrast against the white-backed stem, minimizing visual fatigue and ensuring accurate data capture.
• Versatile Application: Acceptable for use in specialized applications such as Saybolt Viscosity Testing, demonstrating its precision and reliability in critical measurements.

NIST Traceable Calibration for Ultimate Assurance: Each ASTM S12C Thermometer comes complete with a NIST Traceable Certificate of Calibration. This certificate is issued by an ISO/IEC accredited laboratory, providing irrefutable assurance that your thermometer has undergone a rigorous, qualified, and controlled calibration process. The calibration involves a five-point direct comparison against a Precision Reference Thermometer (PRT) and Standard Platinum Resistance Thermometer (SPRT) in a high-stability liquid bath, ensuring accuracy across the entire measurement range. Before calibration, each thermometer undergoes meticulous inspection for any cracks or fluid-column separations, guaranteeing its integrity and reliability from day one.

Detailed Specifications:

• ASTM Number: S12C
• Temperature Range: -20 to 120°C
• Immersion Type: Total Immersion (entire liquid column must be immersed in the measured medium)
• Primary Application: Gravity Testing (also suitable for other general laboratory applications within its range)
• Division: 0.2 degrees Celsius
• Type: Non-Mercury (Blue Indicating Fluid)
• Length: 16.7 inches (425 mm)

Important Usage & Storage Recommendations: To maintain the integrity and accuracy of your non-mercury thermometer, always store it vertically, ideally within a dedicated storage rack, to prevent fluid column separation. For added protection and thermal stabilization in ovens or other exposed environments, consider using a compatible thermometer well.
