CT70 AC Circuit Load TesterExtech Instruments (www.extech.com/instruments), makers of the best handheld test and measurement tools, announces the 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 repairs.

Wiring problems or errors can lead to a range of issues: grounding problems can put users at risk for electrical shock; high resistance in a circuit can cause electrical fires; and performance of components connected to the circuit can also be adversely affected.

Extech’s 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, the CT70 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 CT70 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. To learn more about the CT70, or to find a distributor, please visit www.extech.com/instruments.
