GW Instek GOM-805 D.C. MilliOhm Meter

GW Instek GOM-805 5MΩ D.C. MilliOhm Meter

The GW Instek GOM-805 is a DC milliohm meter from the GOM-800 series. It’s a modern, high-precision programmable instrument designed for low resistance measurements. Here are some key features of the GOM-805:

Measurement Display:
- Equipped with a 3.5-inch TFT color LCD display that shows up to 50,000 counts for clear measurement results.
- The rapid sampling rate allows for 60 readings per second.
- Offers an impressive measurement precision of 0.05%.
Measurement Methods:
- Utilizes the four-wire measurement method for accurate low resistance measurements.
- Includes temperature measurement and temperature compensation functions to meet the requirements of various applications.
Drive Modes (GOM-805):
- DC+, DC-, Pulsed, PWM, Zero, and Standby drive modes.
- Dry circuit mode (available only in GOM-805) for contact resistance measurements.
External Control Interfaces:
- Supports various interfaces, including RS-232C, USB, Handler/Scan/EXT IO, and GPIB (optional).

The GOM-805 is ideal for measuring low resistances in components such as switches, relays, connectors, and PCB tracks. Its easy-to-read display and high precision make it a valuable tool for testing and quality control.
