ASTM S78F Non-Mercury Thermometer, 295 to 315F, NIST Calibration
These liquid-in-glass thermometers have physical and performance characteristics identical to ASTM thermometers for their referenced applications, but have not yet been reviewed and accepted by ASTM for these purposes. They use a safe blue indicating liquid that is biodegradable, nontoxic, and nonhazardous. Dark blue color is easily read against the white-backed stem.
Comes with a NIST Traceable Certificate of Calibration. The NIST Traceable Certificate of Calibration is a 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.
