ASTM S22C Non-Mercury Thermometer, 95 to 103C, NIST

ASTM S22C Non-Mercury Thermometer, 95 to 103C, NIST

The ASTM S22C Non-Mercury Thermometer delivers unparalleled precision and safety for critical temperature measurements, particularly in Saybolt viscosity testing. With a focused range of 95 to 103°C and fine 0.1°C graduations, this total immersion thermometer is engineered for accuracy in demanding laboratory and industrial applications.

Precision Engineering for Critical Applications: Designed specifically to meet the rigorous requirements of ASTM E1, E77, and E2251 standards, the S22C is ideal for Saybolt viscosity measurements, a common test in the petroleum and asphalt industries. Its "total immersion" design ensures the entire liquid column is exposed to the temperature being measured, eliminating potential errors that can arise from stem temperature variations in partial immersion thermometers. The thermometer's overall length of 11 inches (280mm) is optimized for compatibility with standard testing apparatus.

The Safe, High-Performance Alternative to Mercury: This innovative thermometer features a proprietary blue indicating fluid that offers the same reliable performance and accuracy as traditional mercury thermometers, but with significant advantages. The fluid is biodegradable, non-toxic, and non-hazardous, providing a safer choice for both laboratory personnel and the environment. Its vivid dark blue color contrasts sharply against the white-backed stem, ensuring exceptional readability and reducing the risk of reading errors. This makes it an essential tool for organizations committed to green initiatives and enhanced workplace safety.

Unwavering Quality with NIST Traceable Calibration: Every ASTM S22C Non-Mercury Thermometer comes with a NIST Traceable Certificate of Calibration. This certificate guarantees that the thermometer has been rigorously calibrated at five distinct temperature points by an ISO/IEC 17025 accredited laboratory. This accreditation signifies the lab's competence and the reliability of its calibration procedures. The calibration process involves direct comparison against a Precision Reference Thermometer (PRT) and a Standard Platinum Resistance Thermometer (SPRT) in a highly stable liquid bath. Additionally, each thermometer undergoes a thorough inspection for any cracks or liquid-column separations before testing, assuring you of its integrity and accuracy right out of the box. This level of certification provides documented proof of accuracy, vital for regulatory compliance and quality assurance systems.

Best Practices for Optimal Performance: To maintain the integrity and accuracy of your non-mercury thermometer, always store it vertically using a specialized storage rack for thermometers. This prevents fluid column separation, a common issue that can impact reading accuracy. For use in ovens or other exposed environments, a Thermometer Well is recommended. This accessory offers crucial physical protection for the glass and provides thermal stabilization, ensuring more consistent and accurate temperature readings over time.
