Leads are way too short.
Good unit for the price, but the leads are way to short to be usable without splicing.

Temperature sensor
Works as expected. A bit disappointed that it came with individual conductors as flying leads as opposed to a cable with jacket as pictured. Reviewing the description in detail it is indeed stated it comes with conductors. I suggest updating the picture.

If contact opens at 230 Degrees F, what temperature closes circuit again? Also is this compatible with 120v (AC)? Thank you.
Thank you for your inquiry Al1510. The relay contact would close when the temperature drops below 230 F and yes this is compatible with 120 VAC.

Is the brass construction of this switch compatible with PAO or PAE compressor oils. Thank You.
The immersed portion of the switch is made of Brass and Omega does not have any information on being compatible with PAO or PAE oil.
