ASTM S47C Non-Mercury Thermometer, 58.6 to 61.4C, NIST

ASTM S47C Non-Mercury Thermometer, 58.6 to 61.4°C, with NIST Calibration

The ASTM S47C Non-Mercury Thermometer is a premium liquid-in-glass thermometer designed for precise and environmentally safe temperature measurement. It closely mirrors the performance characteristics of ASTM thermometers for their intended applications but has not yet been officially reviewed or accepted by ASTM for such purposes. This thermometer features a safe, blue biodegradable liquid that is nontoxic and nonhazardous, ensuring safety and sustainability. The dark blue liquid provides easy readability against the white-backed stem, making it user-friendly in various laboratory conditions.

Features & Calibration:

• NIST Traceable Certificate of Calibration: Each thermometer is supplied with a five-point calibration certificate from an ISO/IEC accredited laboratory. This ensures high accuracy and reliability in temperature readings.
• Calibration Process: Performed using direct comparison in a high-stability liquid bath with a Precision Reference Thermometer (PRT) and Standard Platinum Resistance Thermometer (SPRT). The thermometer is inspected for cracks and liquid-column separations before testing, guaranteeing quality and durability.
• Measurement Points: Measurements are taken at five temperature points to ensure precision across its operating range.

Specifications:

• ASTM Number: S47C
• Temperature Range: 58.6 to 61.4°C
• Immersion: Total Immersion
• Application: Designed for Kinematic Viscosity measurements
• Division: 0.05°C increments
• Type: Non-Mercury
• Length: 12.6 inches (320 mm)

Usage & Storage: To maintain the integrity and performance of this thermometer, always store it vertically in a storage rack. This prevents fluid-column separation and ensures consistent readings over time.

Additional Information:

• Thermal Stabilization & Protection: For use in ovens or exposed environments, pair the thermometer with a compatible thermometer well to provide protection and thermal stabilization. This accessory shields the thermometer from physical damage and ensures accurate readings in high-heat or dynamic conditions.
• Applications in Laboratories: Ideal for kinematic viscosity testing, environmental monitoring, petrochemical analysis, and any application requiring precise, mercury-free temperature measurement.

The ASTM S47C Non-Mercury Thermometer is a reliable, safe, and eco-friendly option for laboratories, research facilities, and industrial environments that demand high accuracy and compliance with modern safety standards.
