⚖️ Malida Stainless Steel Pressure Aquarium - Pressure Range 0.1-6MPa Review

Bought to line up with my new reverse osmosis system. The plastic fitting that screws onto the sensor itself was very loose and sloppy. still tried it. a leak. Tried to tighten further, still leaking. The next step was to try again and use teflon tape on the metal threads. Still leaked. After 3 more attempts I deleted it for a refund.

These are fantastic gauges for the money. I use three of these to measure the pressure going into the reverse osmosis system from the pump, the pressure in the reservoir and one to measure the pressure in the line to the kitchen. I did without the supplied fittings because I wanted higher quality fittings and a more complex and cleaner assembly as shown in the picture.

The sensor works well and the fittings match the sensor. A problem that many people have is creating a watertight seal between the fitting and the meter. DO NOT SEAL THE THREAD WITH TEFLON TAPE ETC. COVER! The threads on the gauge and fitting are the same and are designed to be used with an o-ring to create a watertight seal. Simply insert a small O-ring into the fitting and screw on the pressure gauge. (I believe a #011 o-ring is used). You will find that this creates an instant seal even when
