Assessing insulation integrity constitutes a critical facet of electrical equipment condition assessment. A quality insulation resistance tester powers through this vital testing role with precision, durability and user-friendliness.

Showing all 3 results

Current Adjustability

Look for adjustable test currents up to 10mA avoiding cable charging effects at lower currents for cables while protecting equipment from damage posed by excessive current.

Noise Immunity

Superior anti-interference filters out disturbances from outside RF noise and other apparatus ensuring measurement precision even in noisy industrial areas.

Wide Measurement Range

Capable of 5kv insulation resistance tester from Mohms to Teraohms, instruments adequately evaluate most cables and rotating machines encountered without range limitations.

Rugged Design

Sealed keyboards and internal components rated IP64 and above withstand wet worksites and occasional knocks. This ensures longterm field use reliability.

Precision Readings

Digital displays read insulation values, capacitance and leakage current to 1% or better accuracy for repeatable, technically sound assessments and documentation.
