The Chroma 19071 and 19073 are the smallest Hipot Testers currently available in the world. Their super-mini size makes them easy to carry, and the large LCD display is helpful for viewing measurement results. The 19071 is designed for AC Hipot testing only. The 19073 combines both AC and DC Hipot with insulation resistance (IR) measurements into a single compact unit.

Model 19071 is a direct replacement for QuadTech Sentry 10 Plus. Model 19073 is a direct replacement for Quadtech Sentry 30 Plus

Open Short Check (OSC)
OSC function is used to check if the connection is open, or if there's a short circuit between instrument and equipment under test.

Ground Fault Interrupt (GFI)
Test environment requirements mandate that test equipment has an auto-interrupt device. This requirement is met with the 19070 Series' Ground Fault Interrupt (GFI) function. When a current measurement of A1 and A2 shows a difference (i2-i1=iH) between the value i1 and actual i2, the GFI will cut the power — protecting the operator.
