In the Test&Measurement World group on LinkedIn, editor Martin Rowe asks, “What’s your favorite test instrument”? He gets some interesting answers, but the two top vote-getters are the Bird Model 43 Wattmeter and the Simpson Electric Model 60 VOM (see right).
About the Bird wattmeter, one engineer said, “That’s easy – The Bird Model 43 Wattmeter. No other instrument has been in production, in its original design, for so long. Since 1952, which makes next year 2012 its 60th anniversary. Also, it must be the simplest, most rugged instrument ever produced. We regularly see Model 43 Wattmeters returned to us for calibration that are 30-40 years old, still working and, when they leave our facility, as accurate as the day they first came of the production line in Solon, Ohio.”
About the Simpson VOM, another replied, “My favorite test instrument of all time is the Simpson 260. I used it back in the 1970s while serving in the US Navy. It is rugged, easy to use, and does the job!”
Those are really two classics, and either is a great choice. But, what do you think? What’s your favorite test instrument?
