Digital multimeter / pen type / with phase sequence detector - HT191
HT Italia presents HT191. It is the logical progression of a multimeter instrument. It has been developed for electrical installation applications to fully meet field operator demands such as precision, ease-of-use and handling, and lower dimensions. The instrument is capable of Voltage TRMS measurement, and automatically finding out AC/DC voltage, resistance, frequency and test continuity.A key feature of H191 is the one-handed test execution without using any other test lead other than the built-in test lead. This is unlike conventional multimeters. This improves simplicity and speed. Measurement of voltage and frequency is done only through contact of built-in lest on cable. With this feature, common phase detection meter's functions are executed and enhanced.
HT191 also includes other new (patented) features such as detection of phase rotation. It also provides measurement of phase coincidence, which is critical for proper connection of two distinct three-phase systems.
