Density and Temperature Measurement

We stock an extensive range of oil company approved high quality hydrometers, thermometers and thermohydrometers for checking the density and temperature of hydrocarbon fuels. They are compliant with the official standard ASTM E2251-14 - Standard Specifications for Liquid-in-Glass ASTM thermometers with Low-hazard precision. 

Each thermometer is filtered with a special blue organic liquid, a lot less toxic than mercury. Thermometers, hydrometers and thermohydrometers all show the standards, the calibration temperature, the surface tension, their individual number and their serial number.

They are all provided with their own plastic case and they come with Traceability and Conformity Certificates. A wide range of each kind of instrument is also available on demand.
