As of August 2018 the State of California has changed the requirements of the “Prop 65” law. We now must list on our website any possible chemicals the can cause cancer, birth defects or reproductive problem.
As an example:
ABS plastic contains styrene
PVC wire insulation can contain Di(2-ethylhexyl)phthalate (DEHP)
electrolytic capacitors can contain Ethylene glycol
Brass can contain Lead
flame retardant pc boards can contain Tetrabromobisphenol A (TBBPA)
Aluminum alloys can contain Chromium
To put it simply we are a small company and do not have the resources to test every single part, so we list every thing as hazardous. Please recycle all electronic parts responsibly and under no circumstance eat, drink or smoke these parts and wash your hands after touching!
Worked great at 115V. Watt meter readings were very much low at 208V.

RE: Re: split phase power measurement
Correction to review by Hal Chamberlin: This particular meter does not use an external current transformer, so it can only be used to measure a single phase. If you check the 360 degree view, you will see that it has two terminals for current sense.
Re split phase power measurement
Actually one CAN measure total power in a typical domestic 120-0-120V split-phase power system. Wire up for single phase measurement per the instructions. Then thread the hot current-carrying wire from the other phase through the current transformer in the OPPOSITE direction. The current transformer will then respond to the sum of the two currents.

Used to monitor current changes in small fluorescent ballasts. Excellent item.
Does what it says, but theres a catch
This is a neat little meter, and it does what it says well. Heres the catch: the current metering is on one phase only, and if you intend to monitor a common household, you will only get half of the picture. Perfect for a load that pulls of both phases 220V, but not so much for watching you houses energy usage.
