DISCONTINUED ITEM- Replacment Model: Hioki SM7110 Super Megohm Meter

The Hioki DSM-8104 Digital Super Megohm Meter is an insulation resistance meter embedded with a low-noise voltage source and high-sensitivity ammeter. The Hioki DSM-8104 has been developed to measure insulating materials of a high resistance value within the range of 1 x 10 ^ 1 to 3 x10 ^16 Ohms and a current within the range of 30 fA to 10 mA.

The DSM-8104 is designed for measuring insulation resistance of insulating materials with a large capacity thanks to the low-noise voltage source embedded in the meter. A liquid crystal display module (240 x64 dots)allows easy viewing of needed information and ease of use.
