In this issue:   Insulation Resistance Testers
  Loop Splitter


Insulation Testers


Use an Insulation Resistance Tester (MegOhmMeter) to check insulation on cables, transformers, motors and electrical equipment.  A variety of portable and handheld models are available, with test voltages to 15kV.  Select a modern digital/bar display or a traditional analog meter.  Use the tester stand-alone or save results and download data to a PC for archiving or analysis. We carry well-known brands including Megger, AEMC, Fluke, Extech, Hioki and Yokogawa.  Also leakage and hi-pot testers.

Leakage Testers  


Loop Splitter


The Laurel QLS Quad Loop Splitter sources four separate 4-20mA outputs from a single input. Outputs can have the same ground or grounds differing by up to ±10V.  Benefits of a loop splitter include:
Load devices can share a common ground.
Each loop drives a single load, which reduces voltage compliance problems.
If one loop opens, other loops continue to operate.
Each loop can be adjusted to compensate for device inaccuracy.
The QLS is DIN rail mounted & ac or dc powered. A yellow LED for each output shows brightness proportional to output level. The front panel also has zero & span adjustments and a loop current test point for each channel.
