CROPICO

CROPICO is a UK-based manufacturer of precision electrical measurement instruments, with a history dating back to the 1950s. The company specializes in low-resistance ohmmeters, including milli-ohm and micro-ohm meters, designed for applications requiring accurate measurement of very small resistances. Their product line includes digital micro-ohmmeters such as the DO4000, DO4001, and DO4002 models, which cover measurement ranges from 4 micro-ohms to 4 kilo-ohms. These instruments are used in quality control, maintenance, and testing of electrical connections, switchgear, transformers, and other components where low resistance is critical. CROPICO meters are built for industrial environments, with rugged enclosures and straightforward user interfaces. They typically offer four-terminal Kelvin measurement to eliminate lead resistance errors, and some models include data logging or PC connectivity. The instruments are not rated for CAT safety categories, indicating they are intended for bench or controlled industrial use rather than live mains testing. 3G Electric supplies CROPICO micro-ohmmeters globally, offering multiple SKUs with datasheets and logistics support. The range covers both standard and NIST-traceable calibration options, though some units are supplied without NIST certification. These meters are suitable for applications such as bonding resistance testing, contact resistance measurement, and cable joint verification. CROPICO instruments are known for their reliability and accuracy in low-resistance measurement, making them a practical choice for engineers and technicians who need consistent results in field or workshop settings.

Pertanyaan yang Sering Diajukan

Pertanyaan umum tentang CROPICO dari 3G Electric.

What measurement ranges do CROPICO micro-ohmmeters like the DO4000 cover?

The CROPICO DO4000 model measures from 40 micro-ohms to 4 kilo-ohms, providing a wide range for low-resistance testing. The DO4002 model extends down to 4 micro-ohms with a maximum of 400 ohms. These ranges cover typical applications such as contact resistance, bonding, and cable resistance measurements.

Are CROPICO micro-ohmmeters suitable for field use?

Yes, CROPICO micro-ohmmeters are designed for both workshop and field use. They feature rugged construction and battery operation, making them portable for on-site testing. However, they are not CAT-rated, so they should not be used on live circuits. They are intended for low-voltage, low-resistance measurements on de-energized equipment.

What is the difference between the CROPICO DO4000 and DO4001 models?

The primary difference is calibration certification. The DO4000 is supplied without NIST traceable calibration, while the DO4001 includes NIST traceable calibration. Both have the same measurement range of 40 micro-ohms to 4 kilo-ohms and similar digital display and low-resistance measurement capabilities.

Do CROPICO micro-ohmmeters use four-terminal Kelvin measurement?

Yes, CROPICO micro-ohmmeters typically employ four-terminal Kelvin measurement to eliminate the effects of lead and contact resistance. This ensures accurate readings even at very low resistance values, which is critical for applications like switchgear contact resistance testing.

Can I get a CROPICO micro-ohmmeter with NIST traceable calibration from 3G Electric?

Yes, 3G Electric offers CROPICO micro-ohmmeters with NIST traceable calibration, such as the DO4001 model. For units without NIST certification, like the DO4000, you can request calibration services separately. Contact 3G Electric for specific calibration options and lead times.

Does 3G Electric supply CROPICO products?

Yes — 3G Electric (S) Pte. Ltd. supplies CROPICO products. We stock the CROPICO catalog and supply genuine factory-original products with full manufacturer warranty and technical support.
