Wahl OM21-4C-1 - Programmable Micro-ohmmeter

OM16 Micro-Ohmmeter is designed for outdoor or indoor use. Easy to use, it performs measurements on inductive and noninductive 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.

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 simplicity of operation. User selects one of 6 test programs (Factory Presets or User Programmable) to find the desired configuration. The instrument is calibrated electronically, with no internal adjustment needed. RS232/IEEE-488 programmable.
