ASTM S22F Non-Mercury Thermometer, 204 to 218F
The ASTM S22F Non-Mercury Thermometer is expertly designed for precise temperature measurement, covering a total range from 204°F to 218°F with fine 0.2° graduations. As a total immersion thermometer, its full 11in (280mm) length must be submerged for accurate readings. It is specifically designated for testing but is versatile enough for any laboratory application requiring measurements within its temperature range.
These liquid-in-glass thermometers serve as a safe, effective alternative to traditional mercury thermometers, offering identical performance and accuracy. They are filled with a proprietary, non-toxic, and biodegradable blue indicating fluid. This dark blue liquid provides a high-contrast, easily readable measurement against the white-backed stem, ensuring clarity and minimizing reading errors. Each thermometer is individually serialized for traceability.
Features:
- Wide Temperature Range: Measures accurately from 204°F to 218°F.
- High Precision: Features 0.2° divisions for detailed readings.
- Safety Compliant: Filled with non-hazardous, biodegradable, and non-toxic blue indicating fluid, offering a safe alternative to mercury.
- Enhanced Visibility: The dark blue fluid stands out against the white-backed glass stem for quick and easy readings.
- ASTM Certified: Fully complies with ASTM E1, E77, and E2251 requirements for accuracy and reliability.
- Primary Application: Officially specified for use in Saybolt Viscosity Testing.
