А key element in the system of public administration by labor protection is receiving reliable information about a condition of working conditions depending on levels of influence of harmful and dangerous production factors. Instrumentional monitoring of workings conditions on workplaces is carry on production control of harmful production factors and procedure of a special assessment of working conditions by test laboratories. Thus one of the tasks demanding the decision is development of algorithm of process of a choice of the measuring instruments satisfying areas of accreditation of test laboratory and to the state requirements to performance of these works. For the solution of an objective the author offers a technique of an optimum choice of the instrument equipment which basis the method of expert evaluations (rank correlation). According to basic provisions of a technique in scientific work the algorithm of process of a choice of measuring instruments for carry on of instrumental control of harmful production factors is presented. Criteria of a choice of devices are considered. The mathematical model of process of a choice of measuring equipment including ranging of criteria of a choice of devices is described. According to results of ranging the leading, essential and less significant criteria of a choice for the instrument group participating in experiment are defined. In view of the leading and essential parameters of a choice of the equipment, the complete set of test laboratory by the necessary instrument equipment, according to area of analytical tasks and conditions of measurement install.

As subject of researches in the scientific article problems of instrument and methodical equipment of the monitoring system and monitoring of dangerous and harmful production factors of the enterprises of mechanical engineering act. For the solution of an objective the technique of a choice of measuring instruments uniting achievements of fundamental analytical chemistry and practical experience of test laboratories is offered. Leaning on the offered technique, the function chart of the mobile control and measuring complex intended for an assessment of the physical production factors and the chemical polluting substances in air of a working zone determined by express method is developed. The devices which are a part of a mobile control and measuring complex completely cover the list of indicators of the harmful production factors controlled in the course of production control and a special assessment of working conditions. The function chart of a mobile control and measuring complex has a flexible configuration, is capable to be modernized depending on parameters of objects of control and technical novelties in the field of instrument making.
