PRODUCT SHOWCASE Butane powered 120W soldering iron Butane powered soldering irons have been available for quite a few years now and they are very handy for all sorts of jobs where a mains-powered soldering iron cannot be used. As good as they are, butane-powered irons have not been a proposition where high power is required, that is, until now. Altronics Distributors now have the Iroda Pro-120 butane iron which is claimed to be equivalent to a 120-watt iron. This has all the convenience features of a normal butane iron, such as quick heating, no power cords, light weight and best of all, it comes with a blow torch tip. This enables it to do all sorts of jobs that just aren’t possible SOUND EASY V2,BOXCAD V2 BY BODZIO SOFTWARE Comprehensive s/design software available distributed by WAR AUDIO Windows interface.SVGA.

The unit is a good size, being 240mm long and about 25mm in diameter. It weighs just 200g with the tank full. Some of these irons are a little tricky to light as they come with a lid mounted flint strike so lighting is a two-handed job. The Iroda iron is much easier; the handle has a built-in piezoelectric thumb starter for easy ignition. You just push it forward with your thumb and the iron is ready within 15 seconds. Pull the starter backwards and the iron is off. The heat control is just below the starter so you have one-hand control for igni­tion and temperature. The iron comes with a 2mm chisel tip which is a bit small for some work but it can be changed for a larger tip, depending on the job to be done. The gas tank gives up to four hours opera­tion and can be refilled using a standard butane refill canister. Normally retailing for $129, the Iroda Pro-120 (Altronics Cat. T-2600) 1GHz 8-digit frequency counter Frequency counters have certainly become cheaper over the years, to the point where it is no longer worthwhile building one from a kit. This nicely made instrument has an 8-digit 7-segment display and is housed in a steel case finished in grey enamel. It is rated for operation up to 1GHz and features high sensitivity. On the front panel it has two BNC sockets, one to cover the range up to 100MHz and the other, involving a prescaler, covering 80MHz to 1GHz. Ten pushbutton switches provide the is available at an introductory price of $99.00 for the month of September and this includes a roll of solder and a butane refill. Spare chisel and torch tips are available for $15.95 each. The iron comes with a 12-month warranty, not includ­ing the tips. The Iroda Pro-120 is available from Altronics, 174 Roe St, Perth, WA 6000.

Interestingly, there is also a hold control which is not a usual feature on a frequency counter. It apparently interrupts the display update circuit so that you can read a frequency, hit the hold button and then disconnect. You can then take note of the reading at your leisure. This could be very convenient in some measurement situations. Other features include LEDs for overrange and kHz or MHz indication. Frequency resolution depends on the range and gating time. For example, with the 1GHz range and 10-second gating, the resolution is 100Hz. On the 10MHz range, with 10-second gating, the resolution is 0.1Hz, dropping to 1Hz resolution if one-second gating is selected. We found it an easy instrument to use and we do like the hold feature. It is available from all Jaycar Electronics stores (Cat QT-2330) and is priced at $299.50. Handheld Gauss/Tesla meter uses Hall effect probe F. W. Bell’s model 5080 Gauss/Tesla will measure up to 30kG (kilogauss) with a basic accuracy of 1%. Key features include auto zero, peak hold, max/min hold, auto range and relative mode. Gauss or Tesla readings can be selected. The 5080 is the top of three models and it also can give readings in ampere/metres and features an analog output (±3V) and an RS-232 port for down­loading data to a PC. Built-in software makes calibration simple with user prompts on the liquid crystal display. The bottom-of-therange model 5060 is a DC measurement unit (ie, not AC fields). It has a basic accuracy of 4% and two ranges of 2kG and 20kG. The models 5070 and 5080 are better, at 2% and 1%, respectively. Frequency band­width of the 5070 is DC to 10kHz while the 5080 is DC to 20kHz. The 5070 has ranges of 200G, 2kG and 20kG, while the 5080 has 300G, 3kG and 30kG. Priced from under $1000, all three models come equipped with a detachable transverse probe, zero gauss chamber, instruc­tion manual, hard carrying case and two 9V batteries. Axial and other style probes are options, as well as extension cables and AC mains adaptors.
