Customers who own infrastructure systems usually require some form of test equipment to assist with the build, operation and maintenance activities.
Given the mixture of old and new technologies now deployed, consequently the range of available test equipment options has grown considerably. And like the infrastructure systems themselves, new functionality demands and obsolescence issues also affect the associated test equipment needs and availability.
@YellowsBestLtd assists Customers by sourcing the required test equipment, supplying either modern or legacy units. Often refurbished ex-hire equipment in excellent condition and at commercially attractive prices makes sense over leasing. This ensures the continued availability of sets of the appropriate specification, which may become discontinued by the manufacturers over time.
If necessary, we can also arrange the repair of existing units, especially those that perform very specific functions that cannot easily be replicated with more recent equipment.
There follows a brief description of many of the types of test equipment available; we would be very keen to hear from you to understand your specific requirements, so please get in touch!
Calibration Checkboxes
Calibration checkboxes, or electrical checkboxes, are used for routine observations of test equipment and allow users to maintain accuracy in between official calibration procedures. Suitable for use with PAT testers and with other testers and instruments.
Calibration Checkbox
Component Analysers
These test the efficiency and status of components including transistors and capacitors. An essential instrument for development engineering when specific components are used in product design.
Component Analyser
Earth Loop Testers
Loop impedance testers, or loop testers, verify the loop impedance of a live electrical circuit without disconnecting from the electrical supply. Most testers include non-tripping RCD technology as standard to prevent unexpected outages.
Earth Loop Tester
Earth Testers
These verify that electrical current paths are safely earthed. Earth spike testers, high current loop testers with earth stakes and leads are available.
Earth Tester
EMF Meters
EMF meters are used for verifying the presence of electrical magnetic fields given off by electrical equipment. Ideal for use in heavy-duty electrical applications and laboratory testing conditions.
EMF Meter
EVSE Testers
EVSE testers are purpose-built for the installation, testing and maintenance of electrical vehicle supply equipment and are an essential for use by electrical vehicle charging point installers, manufacturers and anyone else involved with EVSE equipment.
EVSE Tester
Insulation & Continuity Testers
A wide range of insulation and continuity testing instruments which include Megger insulation testers, insulation resistance testers, Fluke testers and insulation meters from Amprobe, DiLog, Seaward, Metrel, Martindale, Kewtech and Extech.
Insulation and Continuity Tester
LCR Meters
LCR meters get their name from their testing capabilities – they can test inductance (L), capacitance (C) and resistance (R).
LCR Meter
Multifunction Testers
Ideal for use when completing or testing an electrical installation. The huge range of MFTs include the Fluke 1600 range and Megger installation testers.
Multifunction Tester
Optical Fibre Inspectors
Quickly find and inspect the right port. Like having a built in flash-light so you can see in dark areas and dense panels. Pause button holds the image for viewing when it’s hard to get it just right. Bright backlit display. Screw-on probe tips to support most connector types.
Optial Fibre Inspectors
Optical Fibre Visual Fault Locators
Locates fibres, finds faults, verifies continuity and polarity. Locates visual faults including tight bends, breaks and bad connectors. Easily verifies polarity and identifies fibres. Features continuous and flashing modes.
Optical Fibre Visual Fault Locator
Optical Power Meters
Multimode and Singlemode Power and Loss Measurements. Multiple kit configurations with light sources for single mode, multimode and PON fibre optics. Min/Max capability automates tracking of intermittent power fluctuations.
Optical Power Meter
PAT Testers
For Portable Appliance Testing (PAT) routine safety checking of electrical equipment, including dual insulation test voltages and portable RCD lead testing, with adjustable PASS testing limits and substitute/mains powered leakage testing procedures.
PAT Tester
Power Quality Analysers
These provide a comprehensive snapshot of how power is being used in your facility and verify where energy is being lost. The latest power analysers and power analysis tools include those from Fluke and Hioki.
Power Quality Analyser
Production Line Safety Testers
Perfect for laboratories and product design applications, the equipment in this category can be used to verify electrical safety, service equipment using multiple electrical parameters and to simulate PAT conditions.
Production Line Safety Tester
Proving Units
An essential accompaniment to a voltage tester, proving units verify that the tester remains accurate both before and after testing. Both the NICEIC and NAPIT strongly recommend using these regularly when testing.
Proving Unit
RCD Testers
For testing RCD trip time and overall residual current device safety/efficiency. Available are handheld RCD testers, Megger RCD testers, RCD analysers and multifunctional RCD testers which also measure loop and PSC.
RCD Tester
Socket Testers
These testers are placed into a socket to assess faults with the wiring using audio/visual feedback.
Socket Tester
Telecom Datacom Analysers
Ideally suiting traditional telecommunications networking requirements, typically providing testing at V.24, V.35, V.11/X.21 interfaces at rates up to 2 Mb/s. Also a full range of BER/BLER measurements, control-circuit timing analysis with transitions diagrams and storage in text and graphic form.
Telecom Datacom Tester
Voltage Testers
Voltage Testers
These verify the presence of voltage, and allow full test of voltage levels. Instruments are available from the leading test equipment manufacturers such as Fluke, Kewtech, Martindale, Amprobe and Megger.
Most Customers’ infrastructure systems now consist of a wide range of technologies from the very old to relatively recent, having been built to serve operational requirements for a number of years. In many cases, these requirements don’t significantly change, and it therefore makes sense to keep these systems in place to maximise the use of the investment and avoid whole-scale change-outs that would be costly, disruptive and unnecessary.
@YellowsBestLtd locates hard-to-find replacement spare parts to keep legacy infrastructure in operational service that has been deemed ‘obsolete’ by the manufacturers, as well as supplying additional spares for newer systems that can be used to increase capacity or provide alternative interfaces.
Typically we provide refurbished spares, tested and working, but often it is the case that unused products from surplus stocks can be supplied. Hence for both old and new systems, we are usually able to source parts at very commercially competitive rates and with short lead-times.
Here is a selection of items that we’ve recently been helping customers procure or obtain parts for. Keen to hear what requirements you may have, so please get in touch.
