ASTM S64C Non-Mercury Thermometer, 25 to 55C, NIST

ASTM S64C Non-Mercury Thermometer, 25 to 55C, NIST

The ASTM S64C Non-Mercury Thermometer, meticulously calibrated to NIST standards, offers unparalleled precision for your laboratory needs. Designed for total immersion, it provides accurate temperature readings from 25 to 55°C, with precise 0.1°C graduations. At a total length of 15.7 inches (400mm), this thermometer is specified for a range of precision testing methods, including Saybolt Viscosity Testing, but is also highly effective for any application within its temperature scope.

Superior Performance and Safety

This liquid-in-glass thermometer meets the stringent requirements of ASTM E1, E77, and E2251, delivering the same high-performance characteristics as traditional ASTM Mercury Thermometers without the associated hazards. It features a proprietary, eco-friendly blue indicating fluid that is biodegradable, non-toxic, and non-hazardous, ensuring a safer work environment. The vibrant, dark blue liquid provides excellent contrast against the white-backed stem, making it easy to read and reducing the chance of measurement errors.

NIST Traceable Calibration for Ultimate Confidence

Each thermometer is supplied with a NIST Traceable Certificate of Calibration from an ISO/IEC accredited laboratory, guaranteeing its accuracy and reliability. This certification validates that the thermometer has undergone a rigorous five-point calibration process. The calibration is performed using a direct comparison method in a high-stability liquid bath against a Precision Reference Thermometer (PRT) and Standard Platinum Resistance Thermometer (SPRT). Before testing, every unit is meticulously inspected for physical integrity, ensuring there are no cracks or liquid-column separations. This accredited calibration is your assurance that measurements are performed under qualified, controlled conditions.
