ASTM #3F Lab Thermometer, 20 to 760F, NIST Certificate of Calibration
The ASTM #3F General Lab Thermometer, 20 to 760F has a strict manufacturing tolerance. Accuracy is assured by inspection and testing of samples from each production run. The thermometer is supplied with a statement of compliance to E 1 and E 77 requirements. The ASTM Thermometer is yellow-backed glass with permanent graduations, mercury-filled and individually packed in a cardboard tube.
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.
ASTM Number: 3F
Length: 16.3 (415), in (mm)
