Gauges & Meters

And save a bundle. The "Kill-A-Watt" plugs into a wall outlet and accepts the power line for any devices or appliances that draw up to 1875 watts. Identifies energy eaters, tracks efficiency and costs over time, and checks on your electricity provider by...

Knowledge is power - in this case, battery power. You'll know from the easy-to-read gauge on this black-plastic handheld mini-tester whether a battery is good, low or needs to be replaced. The 4-1/4" x 2-3/8" x 1" tester reads "AAA," "AA," "C," "D," 9...

And if so, this pressure gauge will read zero. From Paramount Supply, it has a 2-1/4" face and measures the aforementioned 0 to 60psi/0-4000kPa. Black metal housing has a white face and blue/red lettering. Also has a 1/4” male NPT fitting from the...

This digital volt meter has nothing to do with climbing—it’s a 600A AC/DC digital clamp-on meter, which means it has a handy clamp at one end, allowing you a free hand and the ability to leave circuits on while you test them. Meter measures...

Don’t be cruel and spring random pop quizzes on your cables, but feel free to test them now and then to make sure they’re retaining what they should. Do it with this Model TCT-255K multi-network cable tester kit from Elenco®, which tests...

The always-reliable Tolsen Tools made this Digital Voltage Tester, which tests AC/DC 12~250V. Has a neon indicator bulb and an LCD display to convey voltage. Measures 5-1/4" long x 3/4" wide with a 1/8" dia tester tip and a pocket clip on the back...

We are going to let the photos tell the story on this bad boy. All we know it is a Bruel & Kjaer circa 1950's. The story goes...a few years ago we cleaned a Sears (Remember them?) maintenance floor of all their old testing equipment. Why did they...

Just what you’re looking for... a nice, analog multimeter kit from Elenco®. The M-1250-K model has 29 ranges, and measures AC/DC Volts, DC current, Ohms, diodes, decibels and transistors. Kit has (36) pieces, and the case is pretty much intact...

We don't care if she did go to MIT—she could only have dreamed of today's mulitmeters, like this one, with a 3-1/2 digit, 7-segment 0.5” LCD display with a max reading of 1999. Measures DCV 0.1mV-1000V, ACV 0.1V-750V, DCA 0.1mA-10A,...

Voltmeter Functions 0-300 VDC and 0-600 VDC, Standard Ohmmeter function, Megohmmeter function for testing insulation resistance. Needs a replacement dry cell battery to function as an Ohmmeter. Voltmeter functionality tested. Heavy-duty painted sheet...

This new take-out analog/ballistic meter, a genuine science device, was intended to measure electrodermal activity in humans, if you're into that kind of thing. (We make no judgments here at the home office, lest we be judged.) Has a clear acrylic...

Amps and volts, go together like pretzels and mustard, at least in Philadelphia. Where were we? Yes, you pick from our 0-10VDC in 0.2 volt increments voltmeter or the zero-adjust ammeter (Galvanometer) that reads bipolarity up to 500mA in 20mA increments...
