Saw these at a estate sale along with a bunch of odds and ends....

What are they?


the last pic has writing on the gauge that says "Agricultural Ammonia."

The 2nd picture is an antique 120 volt tester. One lead in each side of a 120 outlet and a good circuit will light the little neon bulb. Haven't seen one in 40 years haven't used one in 50. Have a wonderful day!

Well the last one, though looks like a compression tester, I believe is a setup used to gauge ammonia on sprayers and other agricultural equipment. The 2nd pic is definitely an outlet tester. The first pic looks like some type of battery tester or something.

first pic may be a shunt for a voltage tester.

looks like ammonia gauges actually sell on ebay. Any thoughts on what I should ask for it IF I list it on ebay as is where is?

I DOUBT anybody wants the other two pieces.... in the rear event somebody wants them you can have them for the cost of shipping.

Looks like someone repurposed that ammonia gauge into a homemade compression tester. Sure looks like a hollowed out spark plug turned into an adapter on the end of that hose.

Second one is a neon voltage tester as stated.
First one has me stumped. Is there anything on the bottom or is it just the alligator clip leads attached to studs in a wood block?
