ASTM S58C Non-Mercury Thermometer, -34 to 49C, NIST

The ASTM S58C Non-Mercury Thermometer stands as a pinnacle of precision engineering, delivering accurate temperature measurements while prioritizing safety and environmental responsibility. Designed for demanding applications, this total immersion thermometer boasts a comprehensive range of -34° to 49°C with fine 0.5° graduations, making it ideal for critical industrial and laboratory settings.

Uncompromising Safety & Compliance This thermometer utilizes a non-hazardous, biodegradable indicating fluid, eliminating the risks associated with mercury. Its dark blue fluid provides exceptional visibility against a white-backed stem, ensuring clear and immediate readings. Manufactured to meet the stringent requirements of ASTM E1, E77, and E2251, the S58C offers industry-recognized reliability and accuracy, making it an approved choice for applications such as Saybolt Viscosity Testing and various tank testing procedures.

Precision Through Total Immersion The total immersion design ensures maximum accuracy by requiring the entire liquid column, up to the immersion line, to be submerged in the substance being measured. This method minimizes heat exchange with the ambient environment, providing a true and consistent temperature reading crucial for precise scientific and industrial processes.

NIST Traceable Calibration for Assured Accuracy Each ASTM S58C Non-Mercury Thermometer comes complete with a NIST Traceable Certificate of Calibration. This five-point calibration is performed by an ISO/IEC accredited laboratory, providing an independent assurance of its accuracy and traceability to national standards. The calibration process involves direct comparison in a high-stability liquid bath using a Precision Reference Thermometer (PRT) and a Standard Platinum Resistance Thermometer (SPRT). Furthermore, each thermometer undergoes meticulous inspection for any physical defects like cracks or liquid-column separations before testing, guaranteeing optimal performance from day one.
