LEFOO LF5510 Adjustable HVAC Pressure Control/Steam Boiler Pressure Switch/Single Refrigeration/Air Water Pump Compressor Pressure Switch 14.5psi~145psi

Works very good for the price.

Works find.

I used this to turn a Reverse Osmosis boost pump on and off easy to install and set it's ben in service about 6 months with no issues I set it to come on at 15lbs and off at 45lbs

Appears to be well made, and well-designed. Front cover is easily removable, and adjustment instructions are good, even has a locking plate to hold the pressure screws in place. Electrical contacts easy-to-access. Removed one star because there's no description when you buy it off of what the connection is. It appears to be a 3/8 flare connection.Haven't used it yet, if it does not function as it should I will update this review.

Works as described. I used this to verify pool pressure.

The range is what shows in the photo. The comments of a lower range are wrong

Very stable and don't loose the set calibration,

He comprado dos de estos presostatos, con el rango de 7 psi a 87 psi , y cuando abro la caja el presostato va de 100 a 465 psi. No.me sirve para nada
