## Overview

The PFQ798 industrial pressure gauge by Winters Instruments combines rugged 304 stainless steel construction with brass wetted parts and a glycerin-filled dial for superior corrosion resistance and vibration damping. IP65 certified, it delivers highly accurate dual-scale pressure readings (±1.5% for 2.5" and 4" dials) across a range of applications including pumps, compressors, and hydraulic systems. Designed for professionals demanding reliability and precision in tough environments.

## Description

The Winters PFQ series pressure gauge with brass wetted parts has a glycerin-filled circular dial enclosed in a stainless steel 304 case, and a male connection, and measures pressure with a single or dual scale with an accuracy of + or - 1.5% or 2.5%. The OT58 brass wetted parts are for measuring non-corrosive liquid and gas pressure. The stainless steel 304 case is also corrosion resistant and is Ingress Protection certified IP65 for protection against solid objects, including dust or liquids. The circular dial comes in 1.5" (40 mm), 2" (50 mm), 2.5" (63 mm), or 4" (100 mm) diameters and is filled with glycerin for protection against vibration and pulsation. The dial is white aluminum with black and red markings. It has an aluminum, anodized black, pointer and the lens is polycarbonate for high impact resistance. The gauge measures pressure with a single psi scale or a dual scale of psi/kPa, psi/bar, Hg. vacuum/kPa, or Hg. vacuum/bar. The gauge is accurate to + or - 2.5% of full scale value for the 1.5" and 2" dials and accurate to + or - 1.5% of full scale value for the 2.5" and 4" dials. The male connection comes with a 1/8", 1/4", or 1/2" NPT (National Pipe Thread) rate with a restricted orifice and is located at the bottom or center back of the gauge. The movement is OT59 brass, and the welding is silver alloy. The 6" (150 mm) socket gasket, the fill plug, and the lens ring gasket are all made of nitrile rubber for a tight seal. The over-pressure limit is 25% for pressures up to 1,400psi (9,653kPa) and 15% for pressures over 1,400psi (9,653kPa). The working pressure is a maximum of 75% of full scale value. The operating temperature is -4 to 150 degrees F (-20 to 65 degrees C). This pressure gauge is suitable for pumps, compressors, hydraulic presses, machinery, pneumatic equipment, and motors in harsh environments.Pressure gauges are instruments used to measure the pressure of a gas or liquid inside a vessel and, often, to help ensure the optimal amount of pressure for a given application. Pressure gauges can range from everyday instruments, such as those used to measure the air pressure in a car or bicycle tire, to highly accurate gauges used in mechanical and industrial processing. Most often, pressure gauges measure pressure relative to another reference. For instance, gauge pressure measures pressure relative to ambient air. An example of a pressure gauge measuring relative to ambient air is a tire pressure gauge or a blood pressure gauge. Differential pressure is the difference in pressure between two points, such as when measuring liquid flow along various points in a pipeline. An absolute pressure gauge measures pressure relative to a perfect vacuum, such as an atmospheric or barometric pressure gauge. All types of pressure gauges include either a male or a female mount to connect to the vessel where pressure is being measured, and display results on a dial with varying increments of measure across a given range.Winters Instruments manufactures pressure gauges, thermometers, diaphragm seals, pressure transmitters, and switches. The company, founded in 1953, is headquartered in Toronto, Canada.

Review: For the price, and considering the rated 1.5% accuracy for the 2.5" - pound for pound, these are tough to beat!! - First off - I paid $13.27 for this gauge in the 2.5" size, with the bottom mounted 1/4" fitting, and the rated 1.5% accuracy. I wanted to state that up front, because I am about to make a case how great a gauge this is for the price - which would all change if they raise the price significantly in the future (which happens all the time). This is still a well made, high quality gauge - and the fact I got it for a price that compares to lower quality gauges only makes it that much better! I searched in a number of places for a 30 psi / 2 bar gauge to help calibrate my new Cremina espresso machine. Most of what was for sale in this price range were "Grade B" gauges, with a 2.5% or worse accuracy promise. I then learned about the availability of "Grade A" gauges, and how they also promised better accuracy. This gauge is considered one of those "Grade A" gauges. The issue was what most were charging for Grade A gauges - I was finding prices of $25 to $50 depending on source and brand of the gauge. Even for this particular gauge here, you could pay a lot more for it if you go elsewhere. The $14 range for a gauge will typically get you Grade B, not Grade A. For example, search "Durachoice" here on desertcart, and you will see a Grade B Gauge for more than this; they are still a decent gauge, but these are better. Note that this is a stainless steel, 304 grade metal gauge - no plastic housing here. The picture here on desertcart (at lease when I bought it) makes it look like a grey painted metal. I don't know if that is just a bad picture, or an incorrect image - but rest assured this is a bright, stainless steel gauge! These gauges work well and are very well made. I would recommend them to anyone looking - especially when you compare the $14 price tag to gauges of equal or lesser quality. Thanks for reading!

### ⭐⭐⭐⭐⭐ Nice gauge.
*by J***R on May 19, 2024*

I needed a high pressure gauge, to replace a broken gauge on my scuba tank pressure checker. This worked perfect and is better than the one I replaced. Great price too.
