ASTM S56C Non-Mercury Thermometer has a total measurement range from 19 to 35C, with graduations of 0.02 degrees. These total immersion thermometers are specified for use in bomb calorimeter testing, and can be used for other applications within their range. Total length is 23.6in (600mm).

ASTM Non-Mercury Thermometers meet standard test method requirements for use in their referenced applications. The liquid-in-glass thermometers have the same performance characteristics as ASTM Mercury Thermometers, but use safe blue liquid as an alternative to mercury. The proprietary formula is biodegradable, nontoxic, and nonhazardous. Dark blue color is easily read against the white-backed stem.


  • Meets ASTM E1, E77, E2251 requirements
  • Non-hazardous, biodegradable indicating fluid
  • Dark blue fluid is highly visible against white-backed stem
  • Acceptable for use in Saybolt Viscosity Testing

Select "Add NIST Traceable Certificate of Calibration" above to receive an additional five-point calibration certificate from an ISO/IEC accredited laboratory. This accreditation is your assurance that the calibration is performed in a qualified, controlled lab. The calibration on the glass thermometer is performed using direct comparison in a high-stability liquid bath with a Precision Reference Thermometer (PRT) and Standard Platinum Resistance Thermometer (SPRT) and displays. The thermometer is also inspected for cracks and liquid-column separations before testing. Measurements are performed at 5 temperature points.
