New High-End Visual Infrared Termometer with Higher Resolution Plus Alarms and Time-Lapse Features
Fluke (UK) has introduced the high-end Fluke VT04 Visual Infrared Thermometer, a troubleshooting tool with an infrared heat map which offers higher resolution as well as temperature alarms and time-lapse features. Fluke Visual IR Thermometers fill the gap for when a single- spot temperature reading is not enough and a high-resolution thermal image is more than users need: the one tool combines the visual insight of a thermal imager, the visual images of a digital camera, and the point-and-shoot convenience of an IR thermometer.
Compared to the VT02, the Fluke VT04 offers a wider 28°x28° field of view for improved scanning and up-close evaluation and four times sharper images. It also features a Hi/Lo temperature alarm which enables hot spots to be found in seconds, and time-lapse functionality which automatically monitors equipment over time or automatically captures images after an alarm has been triggered. Images are saved to a micro-SD card, eliminating the need to write down single or multiple measurements: analysis and reporting software is included.
Using the new Fluke VT04 is far faster for conducting inspections of electrical, industrial, HVAC/R and automotive applications than an infrared thermometer, which requires multiple readings and manually recorded results.
The Fluke VT04, like the VT02, instantly detects problems using blended thermal and digital imagery. It will display and save images as full visual, full infrared, or in three blended modes (25, 50, and 75 percent). Markers pinpoint hot and cold spots indicating the hottest temperature with a red box and the coldest with a blue box. A temperature reading is provided at the centre point.
Affordable, compact, and intuitive, the Fluke Visual Infrared Thermometers operate with focus-free simplicity, expanding the user base from senior to junior technicians and broadening the applications for in-house staff as well as creating new business opportunities for service contractors. Images can be imported into SmartView analysis and reporting software, included with the VT04 and VT02, to produce professional reports that document problems detected, or repairs made, for management and customer review.

New On-line Dewpoint Hygrometer Offers Greater Flexibility
The Model 6020 dewpoint hygrometer has been developed by Alpha Moisture Systems (UK) as the next level in moisture analysis in process gases and compressed air.
Displayed units can be °C dewpoint, °F dewpoint, ppm(v), ppm(w), g/m³ or lb./MMSCF, selectable at the touch of a button using one of the three “hot keys”. Molecular masses for calculation of ppm(w) are stored for common gases, or can be entered via the front panel for other gases.
The on-board calculator converts between atmospheric and system pressure dewpoints using pressure units in barg, psig or Pascal x 10³.
The proven robust ultra-high capacitance sensor is available for a number of
ranges optimised for different applications covering an overall range from -110°C to +20°C dewpoint (-166°F to +68°F). Pre-configured tables for all ranges simplify entering calibration data supplied with any sensor, accurate to better than ±2°C dewpoint and the AutoCal feature
offers a user friendly on site function check. Calibrations are traceable to international humidity standards. The sensor is Ex certified for use in Hazardous Areas when connected via a suitable Zener barrier.
Other standard features include linear current output, twin alarm relays and RS485 output, for which optional pc interface and logging software is available.

Tunder and Lightning Detected with Quasi-Electrostatic Sensor
Biral (UK), a global specialist in meteorological equipment and weather sensors, has launched an innovative and efficient thunderstorm detection system. The detector avoids the often-complex method of measuring the radio signal produced by lightning by using a quasi-electrostatic field-change technique.
Biral’s sensor uses multiple co-located antennas of different geometry to differentiate between localised electric field sources and distant yet powerful thunderstorms. Every type of lightning is able to be detected by the high performance system; both cloud to cloud and cloud to ground lightning is monitored and measured.
The detection of thunderstorms is essential to protect lives and infrastructure. Advance knowledge of such storms allows us to prepare for unpredictable weather and dangerous conditions. To allow industries to assess the direction of a thunderstorm as well as its distance from the site, Biral is developing an additional module that uses a radio frequency magnetic direction finding method. Through the quasi-magnetic antenna system, the company has eliminated the necessity for this module to discriminate between lightning and other radio noise, significantly reducing the possibility of false alarms from radio interference.

Users of pneumatic valve positioners can now assess the energy efficiency of their valve installations with ABB’s (UK) new compressed air calculator app for the Apple iPhone and iPad.
Based on the amount of compressed air consumed by conventional positioners, the app shows how using the latest smart positioner technology can help operators to dramatically reduce their energy costs
Easy-to-follow instructions show the user exactly what parameters are needed to calculate any potential savings. The user is prompted to enter the number of pneumatic positioners on site, air cost per standard cubic foot and the percentage of time spent at a steady state to calculate the user's current compressed air energy costs. These costs are then compared to the potential savings that could be achieved using ABB's TZID-C and EDP300 intelligent positioners, where compressed air is only consumed when required.
The app also allows you to measure savings in different currencies, including Sterling, Euros and US Dollars.
