ASTM S1C Non-Mercury Thermometer, -20 to 150C, NIST

ASTM S1C Non-Mercury Thermometer: Precision and Safety Combined

Product Overview Discover unparalleled precision with the ASTM S1C Non-Mercury Thermometer, engineered for a wide range of general laboratory applications. This thermometer offers a broad temperature range of -20°C to 150°C, making it a versatile tool for various scientific and industrial settings. While its physical and performance characteristics are identical to traditional ASTM thermometers, it utilizes an innovative, eco-friendly blue indicating liquid. This biodegradable, non-toxic, and non-hazardous fluid ensures maximum safety without compromising accuracy. The vivid dark blue liquid stands out clearly against the white-backed stem, allowing for quick and effortless readings.

NIST Traceable Certificate of Calibration Each thermometer includes a NIST Traceable Certificate of Calibration, providing you with the ultimate confidence in your measurements. This five-point calibration is conducted by an ISO/IEC 17025 accredited laboratory, guaranteeing that the calibration process meets the highest international standards. The calibration is performed through direct comparison against a Precision Reference Thermometer (PRT) and Standard Platinum Resistance Thermometer (SPRT) in a high-stability liquid bath. Before calibration, each thermometer is meticulously inspected for any physical defects, such as cracks or liquid-column separations, to ensure its integrity and reliability.

Proper Use and Storage: To maintain the accuracy and longevity of your thermometer, it is crucial to prevent fluid column separation. Always store the thermometer vertically with the bulb down, preferably using a designated storage rack. For use in ovens or other exposed environments, consider using a Thermometer Well to provide additional protection and enhance thermal stabilization, ensuring more consistent and accurate readings.
