Of course, with the advantage of built-in computer chips, most electronic devices can do more and better things, and this is certainly true when it comes to electrical service meters. That's why I was very impressed with the Model 1000A clamp-on meter from Extech Instruments of Waltham, Mass. It not only reads volts and amps in true RMS (as well as several other standard measurements), it has a built-in laser non-contact thermometer.
The same thing is true of the HS35 True RMS Stick Meter w/Green Backlight from Fieldpiece of Brea, Calif. It reads true RMS volts and amps; it reads capacitors; it reads temperatures; and it also has a non-contact voltage sensor, so like horseshoes, you can get by with just close. But an added little thoughtful idea for service technicians is a magnetic hanger so the meter doesn't have to be handheld.
