Extech Intros Outlet Circuit Analyzer
Outlet circuit analyzer.
Waltham, MA — Extech Instruments has introduced its new CT70 AC Circuit Load Tester, a sophisticated plug-in tester that instantly analyzes outlet circuit wiring conditions and alerts users to conditions that are potentially hazardous or detrimental to power quality. Electrical contractors can use the CT70 as a valuable tool for increasing business by offering a quick, thorough inspection of all circuits while at a job site to identify additional needed repairs.

The CT70 quickly inspects and detects circuit and wiring problems such as poor ground impedance, false grounds, missing ground fault protection, low voltage availability under load, and high ground-to-neutral voltage. In addition, it tests GFCI and EPD circuits. The color-coded display changes from blue to red, providing a visual alert when a problem is detected.

As an AC load tester, the CT70 provides selectable loads of 12, 15 and 20 amps. Both loaded and unloaded AC line voltage are measured as well as voltage drop percentage, line impedance, peak line voltage and frequency. Outlet tester functions include: GFCI trip time and current measurements; neutral-to-ground voltage testing; hot, neutral and ground impedance testing; and open or reversed wiring detection.

The new instrument is CAT II-rated and includes an AC test cord with standard, North American, 3-prong plug for use on all NEMA 5-15 and 5-20 outlets.
