World Metrology Day raises awareness of the importance of metrology and has been celebrated every year on the 20th May since 2000. Organised by the BIPM (International Bureau of Weights and Measures) and the OIML (International Organisation of Legal Metrology), many national metrology institutes and regional metrology organisations around the globe participate in World Metrology Day[1]; for example, in 2021, thirty-six countries hosted World Metrology Day events.[2] Continue reading →

Hioki Memory HiLoggers record up to 105 channels of data wirelessly using Bluetooth® technology, capturing parameters such as voltage, temperature, resistance or humidity signals. Some models provide complete isolation between channels and high noise resistance. Continue reading →

The advantage of handheld oscilloscopes is that they can be taken to equipment and tested in situ, unlike a bench scope where components have to be dismantled from the equipment and brought to the bench. Continue reading →

News broke yesterday about five cannabis farms having been spotted in Harrow, home to one of England's poshest 'public' schools, where there appears to have been rampant profiteering by unscrupulous landlords in their thousands throughout the country renting out sheds with beds at up to £10,000 a year to migrant workers.

The Martindale VI137002 voltage tester has been approved by the NHS as a standard tester for its Estates and Facilities Division, according to Health Technical Memorandum (HTM) 06-02: Electrical safety guidance for low voltage systems. The document’s purpose is to encourage best practice guidance for the safe systems of work and safety procedures for operation and management of low voltage AC electrical installations up to 1,000V in healthcare premises.  Continue reading →

A Suffolk plumber has been given a suspended prison sentence after carrying out illegal and dangerous gas work at a home in Lowestoft. Barry Goodge, 59, from Oulton Broad, attempted to repair a faulty boiler at a home on London Road South on 28 June 2013, despite not being registered with Gas Safe – a legal requirement in the UK.

Three-phase power quality analysis has never been more affordable with the launch of the Fluke 1730 energy logger, which is 25 percent cheaper than earlier models. Three-phase AC electrical supply has a number of advantages over single-phase as the phase currents cancel each other out, allowing reduced neutral wire size in the case of star wiring or to eliminate it altogether in the case of delta wiring.

In May last year, we reported how the Electrical Safety Council (ESC) was pushing for harsher penalties on companies who do not reinforce electrical product recall policies. After carrying out research into recalled products the ESC found that typically only 10-20 percent of recalled electrical goods are actually ever returned. Continue reading →

Many gas fitters and boiler engineers in the UK may be unaware of new mandatory regulations which will come into effect from April 2014 to measure and record the carbon monoxide (CO) level in the flue gas when a condensing boiler is commissioned. Continue reading →
