Test & Measurement

RS offer an expansive range of test and measuring instruments used in electrical and electronic work.Electrical testing is a vital procedure for any product that uses electricity. The test equipment will reveal:

if any circuits or electrical equipment are being overloaded
locate any potential electrical shock risks and fire hazards
identify any defective electrical work

Precision measurement is essential because if there are measurement errors this can prove costly. By having confidence in each measurement, manufacturers save time and money, and improve the quality of their products.

Types of measurement units

Measurement units can include the following:

Energy - joule ( J)
Power - watt (W)
Electromotive force - volt (V)
Electric field strength - volt per metre
Electric resistance - ohm (Ω)
Electric conductance - siemens (S)
Capacitance - farad (F)
Magnetic flux - weber (Wb)
Magnetic flux density - tesla (T)
Inductance - henry (H)
Magnetic field strength - ampere per metre
Magnetomotive force - ampere (A)

Test and measurement equipment is used in various fields to measure and analyse various components:

Electronics
Electrical
Research labs
Material analysis
Manufacturing, and particle analysis

Range of Test and Measurement Equipment

Ohmmeters - measures the resistance of a component
Ammeters - measures current
Capacitance meters - measures the capacitance of a component
EMF meters - to measure electronic and magnetic fields
Signal generators - generates signals for testing purposes
Oscilloscopes and frequency counters - used to produce signals and then measure the response of the object being tested.
Ammeter - measures current
LCR meter - measures the inductance, capacitance and resistance of a component
Multimeter - general purpose instrument measures voltage, current and resistance
High voltage detectors

Things to consider

The types of test and measure equipment that will be needed depends on the types of materials being tested and which of their properties need to be measured. Size, durability, portability and cost are also key factors.

What is calibration?

Calibration is the comparison of a test instrument against a more accurate standard which can ensure the instruments accuracy. RS offers a great calibration service:
