Triplett MG530-NIST MG530 Insulation Tester with Certificate of Traceability to N.I.S.T
- 125V, 250V, 500V, and 1000V Test Voltages
- Lock Power feature for hands-free operation
- Live circuit voltage indicator
- AC/DC Voltage, Resistance, Frequency, and Continuity measurement
- 3000A AC Current using optional flex clamp

Versatile tester that offers a wide range of functions. It can test insulation resistance up to 4000MΩ using four test voltages (125V, 250V, 500V, and 1000V). Additionally, it can measure AC/DC Voltage, Resistance, Frequency, and Continuity. This tester comes equipped with a Lock Power function for hands-free operation, allowing you to focus on your measurements. It also features a live circuit voltage indicator for added safety. The MG530 includes a 3000A AC Current measurement option using an optional flex clamp.
For enhanced functionality, it offers a LoZ (impedance) mode to identify ghost voltages and an LPF (low pass filter) mode for filtering frequency and harmonic interference when measuring variable frequency drives. The backlit 4000 count LCD display with bargraph provides clear and easy-to-read results. Safety is a priority with a CAT IV 600V safety rating. The package includes test leads, (6) AA batteries, and a carrying case for convenience. The MG530 is backed by a 1-year warranty.
MG530-NIST Comes with Certificate of traceability to NIST standards.
