Thermometers, Mercury, Partial Immersion
- Meet NIST specifications for accuracy
- Graduated-stem thermometers in nickel-plated brass shields
- Shields have suspension ring and perforated bulb guard
- Thermometers are calibrated for 76 mm immersion
Yellow background filled with nitrogen above the mercury. Stems are 6 to 7 mm o.d. Range x graduation intervals are shown in table below.
