HT Italia HT9020 Clamp Meter with Powers/Harmonics and Inrush Currents

Mike — Wed, 24 Aug 2016 03:07:23 +0000

HT9020 Clamp Meter with Powers/Harmonics and Inrush Currents carries out measurements of Active, Reactive and Apparent Power and Energy, voltage and current harmonic analysis up to the 25th order with THD% calculation, in single-phase or three-phase balanced systems. It also tests phase sequence and phase conformity by 1-lead measuring method as well as detects any event related to electric motor starting currents (DYNAMIC INRUSH). DYNAMIC INRUSH™ permits to measure inrush currents with user-defined time frames, providing measurements more reliable than standard fixed time-frame testers. The user has the chance to recall and display the measurement by applying different time frames. For example, if the user carries out a measurement using a time frame of 100 ms, he can post-process the same measurement by applying a time frame of: 16,7, 20, 50, 100, 150, or 200 ms. This grants the utmost flexibility for each measurement, and prevents to measure again and again to get the real inrush current value.

HT Italia HT9020 Clamp Meter WARRANTY CONDITIONS

HT Italia XL422 Three-phase Current Data Logger

The HT Italia XL422 performs measurements and records TRMS AC current up to 2500A in a generic three phase 3-wire system.

The XL422 is part of the HT Data Logger family which includes the following models: XL421, XL423 and XL424

These models can perform measurements and recordings of TRMS AC current up to 2500A from a generic single-phase system.

They can be very useful for various applications:

evaluation of load consumption
verification of nominal power of the incoming supply

The instrument is enclosed in a safe and practical case with a built-in flexible clamp enabling you to clamp-on to a cable or bar with wide dimensions.

Thanks to a sophisticated memory algorithm the instrument is able to record for a considerable time, up to about 1 year! (With a 60 sec integration period for single phase loggers and 5 min integration for 3 phase loggers dependant on battery life). It is also simple and straight forward to use.

With TOPVIEW2004 Windows software, supplied with the model, it’s possible to download and analyse all recorded data directly on your PC.

The high-protection (IP65) casing makes the instrument reliable to use in extreme environmental conditions.
