Quality control of instrumentation does not include procurement of equipment.
I. Laboratory instrumentation
Laboratory instruments are instruments used in physics, chemistry, biology experiments, there are many types of laboratory instruments, the modern commonly used laboratory instruments are test tubes, beakers, evaporating dishes, heap collapses, alcohol lamps, Brinell's funnels, gas-washing flasks, drying tubes, trays balances, measuring cylinders, volumetric flasks, burettes, measuring devices and so on.
Two, instrumentation classification
1, according to the use of purpose and use to points
The main gauge gauge, automotive instrumentation, ionizing radiation instrumentation, tractor instrumentation, marine instrumentation, Aviation instrumentation, navigation instruments, driving instruments, radio test instruments, building materials test instruments, seismic test instruments, geodetic mapping instruments.
2, according to the mechanical industry products, instruments and meters
Industrial automation instruments, electrical instruments and meters, optical instruments, analytical instruments, laboratory instruments and devices, materials testing machines, meteorological and marine instruments, film machinery, photographic machinery, copying and microfilming machinery, instrumentation components, such as 13 categories.
They are more versatile, larger batch, or the necessary foundation for the instrumentation industry.
Three, the principle of equipment procurement
1, to the good reputation, stable quality of supply supplier procurement. Reasonable price, advanced technology, timely delivery, after-sales service is guaranteed.
2, the quality of equipment is reliable, meet the technical requirements, can ensure the stability of production or operation. In line with national policies and regulations.
Four, equipment procurement process
Equipment procurement is the process of searching for and purchasing the tools necessary for the effective operation of the company. There is no universal format for the equipment procurement process. The equipment procurement process basically covers the steps a company takes to acquire the tools it needs, usually from the moment a purchase request is made. The steps taken will vary depending on several factors: the size of the company, its location, its budget, its spending power and its structure.
The most critical parts of the equipment purchasing process are identifying the need, creating a purchase request, checking and selecting suppliers, negotiating, purchase order creation, receiving the equipment, the three-way matching step, arranging for payment, and record-keeping.
