ASTM S19C Non-Mercury Thermometer, 49 to 57C, NIST

ASTM S19C Non-Mercury Thermometer: Precision, Safety, and Compliance

Experience accurate and reliable temperature measurements with our ASTM S19C Non-Mercury Thermometer. Designed for specific applications such as Saybolt Viscosity testing, this liquid-in-glass thermometer offers a precise range of 49 to 57°C with fine 0.1°C divisions.

Key Features:

• NIST Traceable Calibration: Each thermometer comes with a comprehensive five-point NIST Traceable Certificate of Calibration from an ISO/IEC accredited laboratory. This ensures superior accuracy, providing confidence in your readings and meeting stringent quality standards. Calibration is performed through direct comparison in a high-stability liquid bath using Precision Reference Thermometers (PRTs) and Standard Platinum Resistance Thermometers (SPRTs), guaranteeing exceptional precision.
• Safety First: Utilizing a safe, blue indicating liquid, this thermometer is biodegradable, nontoxic, and nonhazardous. This eliminates the risks associated with mercury-filled thermometers, making it a responsible choice for both laboratory personnel and the environment. The dark blue liquid stands out clearly against the white-backed stem for easy readability.
• ASTM Equivalence: While awaiting formal ASTM review and acceptance for specific referenced applications, this thermometer boasts physical and performance characteristics identical to traditional ASTM thermometers.
• Total Immersion Design: Engineered for total immersion, it ensures the entire liquid column is at the temperature being measured, providing the most accurate results for its intended use.
• Durable and Reliable: Each thermometer undergoes rigorous inspection for cracks and liquid-column separations prior to calibration, ensuring its integrity and longevity.
• Compact Design: With a length of 11 inches (280mm), it's a practical size for various lab setups.

Pro Tip for Longevity: To prevent fluid column separation and maintain calibration accuracy, always store Non-Mercury Thermometers vertically, ideally in a dedicated storage rack. For enhanced protection and thermal stabilization in ovens or other exposed environments, consider using a Thermometer Well.
