Sentinel Series Hipot Testers

The Sentinel Series is a versatile and cost-effective range of electrical safety testers designed for compliance, production, and research applications. Covering AC/DC dielectric strength, insulation resistance, and earth bond testing, the Sentinel Series ensures accurate and reliable hipot and safety measurements that meet international standards including IEC, EN, UL, and CSA.

With models ranging from the entry-level Sentinel 200 to the more advanced Sentinel 500 and Sentinel 501, the series offers a scalable solution for laboratories, QA departments, and manufacturing facilities. Features such as programmable test sequences, high power capability, ARC detection, and automation interfaces make the Sentinel Series ideal for both manual and automated testing environments.
