S431 INSULATION RESISTANCE TESTER

The S431 insulation resistance tester, also known as a high‑voltage insulation resistance tester, megohmmeter, high‑voltage megohmmeter, or digital high‑voltage megohmmeter, is typically used for insulation testing in laboratories or on-site.

S320A FULLY INTELLIGENT WIRELESS HIGH AND LOW-VOLTAGE PHASE VERIFIER

The S320A fully intelligent wireless high‑ and low‑voltage phase comparator, also known as the fully intelligent wireless high‑voltage voice‑enabled phase comparator or wireless high‑voltage phase detector—often simply referred to as a phase comparator or phase detector—can perform phase comparison at distances of up to 160 meters in open areas. It supports fully intelligent phase verification for voltage lines ranging from 1 V to 550 kV. For bare conductors at 35 kV and below, direct contact phase comparison is possible; for bare conductors above 35 kV, non‑contact phase comparison is employed.
