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!
Nicely made unit. Be careful not to drop them or you may cause air gaps between the stages that will reduce cooling/heat transfer effectiveness.
I use mine to cool a camera module for a night sky camera. I can not fairly comment on the free air cooling ability since I run mine in an evacuated enclosure. I will say that I had to be careful so I did not cold damage the camera module. I control the peltier with a MPJA 32764 temp controller. When I power up the peltier the first time running in a vacuum it bottomed out the temp controller display before I realized it. Fortunately the camera module electronics were not damage with a brief visit to well beyond -60F. The waste heat is sunk into the aluminum casing to keep the camera window dew and frost free. I believe the spec claiming a 107c possible differential. The speed at which it chilled the camera module in a vacuum makes be believe it would work well for more common uses at normal atmospheric pressure.
