Questions related to metrological assurance of the thermomechanical indicators of pre-explosive concentrations of hydrocarbons in the air using as an example the STM-30-50 plant are considered. Causes for the appearance of an additional error in these measuring instruments and methods of eliminating (decreasing) this error are analyzed.
