Simpson Electric 260-9S / 260-9SP Industrial Safety VOM

The Simpson 260-9S and 260-9SP are the current CAT III 600 V industrial-safety versions of the Simpson 260 – the analog Volt-Ohm-Milliammeter Simpson has manufactured continuously since 1936 and the meter that made ‘Simpson’ shorthand for a serviceman’s multimeter for three generations. The needle-and-mirrored-scale display remains the practical choice for reading a fluctuating signal that a digital display would smear into unreadable digit-flicker, which keeps the 260 on many industrial procurement lists next to digital instruments a fraction of its price. The mirrored scale eliminates parallax error – line the needle up with its reflection and the reading is taken from directly overhead, which is the small procedural detail that separates a 2 percent full-scale reading on the meter from a 4 percent reading in the hand of a technician eyeballing the scale from an angle.

The -9SP variant adds overload protection to the meter movement; both are certified to EN 61010-1 to 600 V Category III – the industrial safety class specifying safe measurement inside distribution-level electrical systems and at industrial equipment terminals. Each meter ships with a nylon-padded safety-orange case, a test-lead set with retractable banana jacks and probe tips, and an alligator clip set – which puts the 260-9 into field service on arrival, no accessory-ordering follow-up required.
