Digital Insulation Tester 3552BT – Kyoritsu

Key features:

• Six insulation test voltages: 50, 100, 125, 250, 500 and 1000 V for electronics through to high-voltage work.
• Wide insulation resistance range: Measures up to 40 GΩ at 1000 V, with ±2% rdg ±2 dgt accuracy.
• Fast measurement: Kyoritsu says it reads in about 0.5 seconds, which it calls world’s-fastest class.
• Automatic discharge: Safely releases stored charge from the circuit under test after insulation testing.
• Continuity testing: Auto-ranges across 40 Ω, 400 Ω and 4000 Ω, with ±2.5% rdg ±8 dgt accuracy.
• AC/DC voltage measurement: Reads AC 2.0–600 V (45–65 Hz) and DC ±2.0–600 V, with ±1% rdg ±4 dgt accuracy.
• Bluetooth 5.0 and app support: Sends results wirelessly to the KEW Smart Advanced app on iOS and Android.
• Data storage and PC link: Saves results to internal memory and connects to a PC by USB for reporting.
• Dimensions: 97 (L) × 156 (W) × 46 (D) mm.
• Weight: About 490 g with its four AA batteries.
