Insulation resistance is vital to designing a safe and effective electrical system. Matching insulation requirements with voltages ensures the most efficient and low cost insulation for a conductor.

Determining this insulation efficiency and keeping a record of the data is what the Digital Insulation Tester and Data Logger was designed for. With insulation measurements up to 4000MΩ with 4 different range settings. This instrument also features the ability to download large amounts of data to a PC for easier analysis and manipulation. With the ability to record up to 16,000 readings and a programmable test rate of 1 to 65,000 seconds per sampling.

Testing insulation efficiency versus the actual power flowing through the conductor demonstrates how safe and efficient a circuit is. This meter has the added ability to measure AC and DC voltage up to 600V. The 380366 Digital Insulation Data Logging Tester User Manual is attached to this page to answer any further questions.
