These thermometers for petroleum product experiments are highly specialized. They cover various key temperature ranges, such as -30 ~ 50°C for oil cylinders and 30 ~ 200°C for melting points, with graduation values as precise as 0.2°C for accurate readings. Available in rod and internal standard shapes, they fit different experimental setups. With appropriate dimensions like total length (300±10 mm to 350±10 mm) and outer diameter (6 ~ 10 mm), and specified immersion depths (full immersion or fixed lengths like 65 mm, 75 mm), they ensure reliable temperature measurement in experiments like determining crystallization points, pour points, and melting points, meeting the strict requirements of petroleum product testing.
