ASTM-Equivalent S57C Non-Mercury Thermometer, -20 to 50°C
Ensure precise temperature readings for your laboratory applications with our ASTM-equivalent S57C Non-Mercury Thermometer. While its physical and performance characteristics are identical to traditional ASTM thermometers for the specified application (Tag Closed Low), this model offers a safer, more environmentally friendly alternative.
Key Features:
- Safe Indicating Liquid: This thermometer uses a safe, biodegradable, non-toxic, and non-hazardous blue indicating liquid.
- High Visibility: The dark blue liquid stands out clearly against the white-backed stem, ensuring easy and accurate readings.
- Durable Construction: The permanent markings are fused to the glass, making them resistant to chemicals and fading over time.
- Serial Number: Each thermometer is individually serialized for traceability.
Though it meets the test methods of ASTM E1, E77, and E2251, it has not yet been officially reviewed and accepted by ASTM for these specific purposes.
