ASTM S57C Non-Mercury Thermometer, -20 to 50C, NIST

ASTM S57C Non-Mercury Thermometer, -20 to 50°C, NIST Certified

The ASTM S57C Non-Mercury Thermometer is a reliable, eco-friendly alternative to traditional mercury thermometers, designed for accurate temperature measurement in a variety of laboratory and industrial applications. It features a safe, biodegradable, non-toxic, and non-hazardous blue indicating liquid for precise readings. The dark blue liquid contrasts sharply with the white-backed stem, making measurements easy to read, even in challenging environments.

Key Features:

• Safe and Eco-Friendly: Replaces mercury with a biodegradable, non-toxic, and non-hazardous blue liquid.
• Accurate and Reliable: NIST Traceable Certificate of Calibration ensures high accuracy, with calibration conducted at 5 specific temperature points using advanced methods.
• Durable Construction: Designed to prevent liquid column separation. Inspected for cracks and separations before testing.
• Wide Temperature Range: Measures temperatures from -20°C to 50°C with 0.5-degree divisions for precise readings.
• Compact Design: 11.4 inches (290mm) in length, ideal for portable and laboratory use.
• Partial Immersion: 2.3 inches (57mm) immersion depth for specific applications.

Calibration and Certification Details:

This thermometer comes with a NIST Traceable Certificate of Calibration, providing assurance of accuracy and compliance with international standards. The calibration is conducted in an ISO/IEC 17025 accredited laboratory, using a high-stability liquid bath, Precision Reference Thermometers (PRT), and Standard Platinum Resistance Thermometers (SPRT). With 5-point calibration, it ensures consistent and precise measurements for critical applications.

Applications:

• Ideal for laboratory, industrial, and educational environments.
• Frequently used in ovens, environmental chambers, and other temperature-sensitive setups.
• Suited for ASTM applications (Tag Closed Low) requiring non-mercury alternatives.

Additional Notes:

• Always store the thermometer vertically in a storage rack to prevent liquid column separation.
• For enhanced protection and thermal stabilization, consider pairing it with a Thermometer Well, particularly when used in ovens or exposed environments.
