Portable Micro-Ohmmeter

OM16 (formally RM116) Micro-Ohmmeter is designed for outdoor or indoor use. Easy to use, it performs measurements on inductive and non-inductive resistances with a DC current. Its large interactive display informs the operator in real time about the type of measurement, range, calculation conditions (resistance calculated according to a reference temperature), thresholds status and values. Designed for harsh environments, it is encased in a Pelicase type carrying case and features washable plastic keyboard and key-locked measurement plugs.

Features:

• Low resistance value measurement in 4-wire configuration (0.1mW) to (2500 W)
• Measuring current adaptable to the measuring range from 10A to 100mA
• Inductive resistance measurement (coils, motors and transformers)
• Non-inductive resistance measurement of earth bonding, coating, contact resistances

Bench-Top Micro-Ohmemters

OM21 Micro-Ohmmeter can be used for measurement of thermistors and heat-sensitive components. It can be powered from mains or from rechargeable batteries. The instrument is calibrated electronically, with no internal adjustment needed.

OM22 Micro-Ohmmeter is specifically designed for industrial test and pre-configured for each user, making its principal characteristic simplicityof operation. User selects one of 6 test programs (Factory Pre-sets or User Programmable) to find the desired configuration. The instrument is calibrated electronically, with no internal adjustment needed. RS232/IEEE-488 programmable.

Features:

• Programmable
• Four-wire resistance measurement of very low values
• Resolution of 0.1mW to 20k W
• Accuracy of 0.03% and a display over 26,000 counts
• Display of the measured resistance value reduced to 20 °C
• Mains supply or rechargeable batteries
