Resistance meters GW INSTEK GBM, GCT, GOM, etc.

Resistance meters of grounding devices (metal communication tester) GW Instek are resistance meters of low-resistance grounding circuits (transient resistance, metal communication). The devices provide autonomous operation as an independent unit as a milliohmmeter or in combination with a multifunctional electrical safety tester GPT-79000 to perform additional ACW/DCW/IR tests before, after or simultaneously with a metal communication test (ACW/DCW mode only).

GW Instek milliometers are devices for measuring resistance. Features:

• 5 digits, dynamic range "50,000".
• The basic measurement error is ± 0.05%.
• The maximum resolution is 1 mkOm, the test current is up to 1 A (post).
• The measurement mode is "dry contact" (U test ≤ 20 mV) for compliance with the MIL-STD-1344 standard (only GOM-7805).

Battery testers (internal resistance meters) GW Instek. Features:

• "2 in 1": measurement of internal resistance (Rvn) and constant voltage of power supplies (V).
• Support for all types of chemical current sources: batteries and batteries, rechargeable batteries, as well as DC backup power systems in order to analyze their condition and assess the level of charge.
• Measurement speed: 3 ism/s, 14 ism/s, 25 ism/s, 65 ism/s.
