Testo’s latest HVAC/R plumbing tools webinar introduces a new flagship digital refrigeration manifold: the Testo 570s. Offering the best functionality and the greatest number of features of any Testo digital manifold, the 570s is the most sophisticated model in Testo’s series of digital refrigerant testers. As detailed in the webinar, the Testo 570s Digital Manifold supports additional functions, such as Pressure Testing, Vacuum Measurement, Compressor Test (DLT), Target Superheat, and Delta-T Measurement, with dedicated menu options and data screens. It also provides datalogging, delivers an exceptionally long battery life, and is compatible with Testo’s new 560i Refrigerant Scales; existing Bluetooth Smart Probes/Clamps including the 770-3 Clamp Meter; and updated Testo Smart App. Continue reading →

Founded in 1844 on the principles of precision, reliability, and quality, Kern is one of the world’s leading manufacturers of high-accuracy balances/scales, microscopes, and moisture analysers. Kern’s comprehensive catalogue of equipment provides educational facilities, scientific laboratories, industrial companies, and utility suppliers with complete solutions. As evidenced recently when a German wastewater plant invested in a Kern microscope to monitor the efficacy of water treatment and a Kern moisture analyser to reduce wastage. Continue reading →

Acoustic imaging cameras, otherwise known as sonic or ultrasonic imagers, are popular amongst facilities managers, especially those working in industrial or high-voltage settings. They are extremely easy to use and highly effective at finding air/pressurised leaks and partial discharge/corona. Acoustic cameras detect audible and/or ultrasonic sound; convert it into a sound map; then superimpose this map onto a digital image of the inspection area, allowing you to pinpoint the source of the leak or electrical fault accurately, simply, and quickly. As sonic imaging is a relatively new preventative maintenance/inspection technology, it can be difficult to know what makes a good acoustic camera. Thankfully, Teledyne FLIR has outlined six things to look for when purchasing an ultrasonic imager. Continue reading →

Recognising the dangers posed by toxic gases encountered in farming, Crowcon has produced a white paper specifically for the agricultural sector. Titled Why Gas Detection is Crucial in Farming & Agriculture, this paper outlines the gas hazards farmers should look out for, explains the relevant standards that need to be met, and details helpful ways to protect yourself, your staff, your stock, and, ultimately, your livelihood.

Gravity varies depending on where you are around the world, up to approximately 0.5%. Local gravity correction is typically the largest environmental influence acting on the deadweight tester. When you are carrying out calibrations in your laboratory or on-site the local acceleration of gravity, where the pressure calibrator is being used, needs to be accounted for to ensure calibration accuracy...

Power quality problems aren’t always immediately recognisable. Without power quality monitoring, issues within electrical distribution systems and/or faults with equipment may be misdiagnosed as, for example, an old breaker that needs to be replaced. Misdiagnosis could lead to ineffective 'corrections', for instance, resetting the equipment or circuit. Spotting the signs of power quality issues early is essential to prevent further damage to systems or equipment. Once symptoms have been recognised, you can use a power quality analyser, such as Fluke’s 1770-Series Power Loggers, to monitor loads, voltage, current, harmonics, and unbalance or disturbance patterns.[1] Continue reading →

Oxfordshire City Council commissions ODS (Oxford Direct Services) to maintain council properties including 7000 residential homes, as well as parks and streets across the county. To fulfil such an important, varied, and large-scale contract, ODS employ a team of over 200 builders, plumbers, electricians, and other skilled tradesmen to conduct maintenance and repair work. Staff use company equipment, therefore, to ensure their safety ODS has implemented a preventive maintenance program. As part of this program, Seaward equipment, such as the Apollo 600+ with PATGuard 3 Software, is used to check the electrical safety of company equipment including drills, portable lighting, vacuum cleaners, heaters, compressors, and batteries.   Continue reading →

London Underground is one of the world’s largest underground passenger railway networks. It operates a system of 11 train lines, 270 stations, and 250 miles of track covering Greater London and parts of Hertfordshire, Buckinghamshire, and Essex. Serving over five million passengers a day, London Underground must ensure all its in-service items meet electrical safety requirements. They have been a long-time user of Seaward’s PAT testing equipment and currently employ 12 Seaward Apollo 600+ PAT Testers with PATGuard 3 Testing Software to verify tens of thousands of items across 500 sites.
