Electronic Megohmmeter Supco M501 1000V 1000 Megohm Insulation Tester

Description

Product Overview

The Supco M501 electronic megohmmeter is engineered for professionals who demand precise insulation testing in demanding environments. Featuring a robust 1,000 V test voltage, the instrument can accurately assess insulation resistance values up to 1,000 megohms, making it suitable for a wide range of electrical equipment, from small motors to large generators. The device is housed within a hard‑shell service case that not only protects the meter from drops and impacts but also provides a convenient handle for easy transport. Included with the unit are high‑quality test leads equipped with alligator clips, ensuring secure connections and reliable measurements. The zone‑type scale offers intuitive visual feedback, categorizing insulation condition as “bad,” “caution,” or “good,” which helps users quickly interpret results and take appropriate action.

Usage

Designed for field service engineers, maintenance technicians, and safety inspectors, the M501 excels in environments where quick, accurate insulation verification is critical. Whether you are performing routine preventive maintenance on industrial machinery, troubleshooting motor windings, or conducting safety audits on high‑voltage installations, this megohmmeter delivers consistent performance. Its compact size—measuring just over 10 inches in length—and lightweight construction (approximately 1 pound) allow it to be easily carried in a tool bag or mounted on a service cart. The built‑in case protects the instrument from dust, moisture, and accidental impacts, ensuring reliable operation even in harsh workshop or plant conditions. The clear zone‑type display reduces the learning curve for new users while providing seasoned professionals with rapid, at‑a‑glance status indicators.

FAQ

What types of equipment can I test with the M501?

The M501 is suitable for testing insulation resistance on motors, generators, transformers, cables, and control panels where a 1,000 V test voltage is appropriate.

How does the zone‑type scale work?

The scale divides the display into three colored zones—red for “bad,” amber for “caution,” and green for “good”—allowing you to quickly assess the condition of the insulation based on the measured resistance value.

Is the service case waterproof?

The case is water‑resistant and protects the meter from splashes and light rain, but it is not designed for submersion.

Can I use the M501 for low‑voltage testing?

Yes, the meter can also be set to lower test voltages for delicate equipment, though the primary design focus is on the 1,000 V range for high‑resistance measurements.

What warranty does Supco provide?

Supco offers a standard one‑year limited warranty covering manufacturing defects, along with optional extended service plans for added peace of mind.
