NEWQUICK DRAW PRECISION MARKING TAPES

the leading tool guru in the USA, noted that it is, “the best tape measure ever”. “If you work with a tape measure every day, or just once in a while on a home project, you will love the new innovation of the QuickDraw self-marking tape measure,” says Ryan Hunt, Sales and Marketing Director Vermont Sales. “It makes a perfect circle, or half circle, gives you an extra hand to hold the blade in place for a more accurate mark, duplicates measurements easily, makes difficult measurements easy, saves time and frustration by never having to look for a pencil or a sharpener again and comes with 10 refills. The QuickDraw is built to meet the toughest demands of the professional contractor,” he says.

mark. The rugged co-moulded case is secured by industrial STAR-drive screws. The tape hook is secured with three rivets and a steel backing plate and you can extend the stand-out of the blade up to 140 cm plus with your free hand. The self-marking QuickDraw tape measure makes 2000+ marks per load. Reloading takes only seconds, and your tape comes with 10 refills that will make over 20 000 marks. The tape also includes a hook/clip that can be attached to your belt or toolbox (a key chain option is also available as an extra accessory). The awards and reports have flowed in for the new QuickDraw tape measure after it was introduced in the USA. Construction Home Depot rated the QuickDraw marking tape measure as the top tape measure, while Dane Scarborough,

pack) and can be reloaded in less than 10 seconds. QD Graphite refills are also available. Lock the blade to draw circles and lines or a radius and hold the corner of the hook on the centre point. The marking system works as follows; there is a stick of graphite directly above the small steel wheel. As the wheel rolls, it transfers the graphite to the surface being marked. It works on all kinds of surfaces, no matter how rough, because the mark is made by a small hardened steel wheel, which rolls out the graphite. The result is a pencil line, without the pencil, and it never needs to be sharpened. A white refill marker is also available as an extra accessory.

ACCURATE, RELIABLE RESULTS WITH THERMAL CAMERA

L eading an industrial maintenance team requires a combination of communication skills, industry knowledge and technical expertise. Implementing standard work and a preventive maintenance pro- gramme is more than just good for business – it also aligns the team with a common goal of safely and efficiently keeping the plant up and running. Choosing the right tools can make a significant difference in the success of these types of programs. Comtest is pleased to announce Fluke’s new Ti300+ infrared camera for reducing unexpected breakdowns and improv- ing work execution by helping maintenance teams to find issues before they become problems. The Ti300+ has the resolution and accuracy needed to clearly reveal temperature differentials or demonstrate progressive heat changes over time. With LaserSharp™ AutoFocus the Ti300+ ensures focused images, every single time. With the touch of a button, the built-in laser distance meter calculates and displays the distance to the designated target on the camera screen and takes the image in focus. Most importantly, temperature readings from in-focus images are highly accurate. The Ti300+ enables the team to get clear images with touchscreen simplicity, while maintaining a safer distance from operating equipment. Features include:

• Engineered and tested to withstand a 2 m drop. • Manual or automatic focus.

In conjunction with Fluke Connect desktop software for connectivity, the Ti300+ is able to generate professional reports in minutes, while efficiently capturing full radiometric data to support the maintenance program. • Edit and optimise images. • Combine infrared and visible images for simpler analysis. • Create detailed reports. • Access thermal images from cloud storage. • Organise and search images by asset, severity and title. For thermal images to illustrate an issue, users need to know the equip- ment and understand the subtle difference between normal and abnormal operating temperatures. Also, confidence in the ability to capture accurate thermal images plays a significant part, and having a Fluke Ti300+ thermal camera with LaserSharp AutoFocus makes taking everything much easier. Finally, users need a thermal camera that is rugged enough to capture qual- ity infrared images even if it gets dropped (up to two metres).

• 320 x 240 resolution. • Measures up to 650 °C.

HIGH DEFINITION OSCILLOSCOPE MAXIMISES PERFORMANCE AND VALUE

T he WaveSurfer 4000HD High Definition Oscilloscope (HDO) from Teledyne LeCroy is the first in its class to feature 12-bit vertical resolution at all times, showing clean, crisp waveforms on a bright, 12.1” touch screen display. WaveSurfer 4000HD is available in bandwidths from 200 MHz to 1 GHz, with sample rates of up to 5 GS/s and up to 12.5 Mpts of acquisition memory on each channel (25 Mpts inter- leaved). It offers versatile built-in capabilities for embedded systems debug and is compatible with Teledyne LeCroy’s comprehensive probe offerings. Design and test engineers have come to demand the signal detail and measurement accuracy that comes with a 12-bit HDO when debugging deeply-embedded systems in IoT, automotive, switch-mode power

– and highest accuracy – 0.5% versus competitors’ 2.5% at 1 mV/div gain setting. Displayed waveforms are crisper, cleaner and provide visibility into signal details that are often lost in the noise on other oscilloscopes, including those with advertised 10-bit and 12-bit ADCs. WaveSurfer 4000HD further increases its value by integrating multiple instruments into one and reducing clutter on the test bench: it offers an optional 16-channel Mixed-Signal Oscilloscope (MSO), Arbitrary Waveform Generator (AWG), Frequency Counter and Spectrum Analyzer (available early 2020).

supply and other control system designs. Other oscilloscope manufacturers make claims of 10-bit or 12-bit resolution, but their oscilloscopes lack low- noise and low-jitter components throughout their acquisition system and require tradeoffs of channel count, bandwidth or sample rate to achieve high resolution and lower noise. TheWaveSurfer 4000HD answers the call as a highly affordable instrument that leverages Teledyne LeCroy’s HD4096 High Definition technology to deliver 12-bit resolution all the time. HD4096 technology utilises a system design of high signal-to-noise input amplifiers, high sample rate 12-bit ADCs, and a low-noise system architecture to enable capture and display of waveforms with 16x more resolution than 8-bit oscilloscopes. WaveSurfer 4000HD delivers the best performance in its class, demonstrating the lowest baseline noise – 2.5 times better than competitive oscilloscopes with 12-bit ADCs and eight times better than competitive oscilloscopes with 10-bit ADCs
