TERMÓMETROS

Mercury thermometers;

Most thermometers upstream, whose volume changes with temperature evenly.

Industrial mercury thermometers work the same way, the only thing that differentiates it in size; which is designed for the manipulation of the same As a result an essential product.

Thermohydrometers with ASTM specifications for Superior Gasoline, Regular Gasoline, Diesel, Bunker, JETA1, AVGAS

The hydrometer method is widely used for determination of API gravity, density and relative density (specific gravity) of Crude Oil, derivatives and LPG.

The operation is very conventional; The hydrometer or thermohydrometer is left to float freely in the sample and the reading is taken directly on the scale;

• The hydrometers require an additional thermometer to take the reading,
• Thermohydrometers have it incorporated.

In conclusion we can define that thermohydrometers are a compound element that favors handling and precision when taking samples.

The bimetallic thermometer; instrument used to measure the temperature by the contraction and expansion of two different metal alloys of high and low coefficient of expansion.

The bimetallic thermometers are constituted by a tube inside which is placed a helical bimetallic spiral,

Said spiral is welded at one end to the bottom of the tube and on the other to a transmission rod in turn connected to an indicator needle.
