ReviewsPressure And Vacuum Gauges

Winters Instruments - PFQ804R1 -804R1 PFQ Series Stainless Steel 304 Single Scale Liquid Filled Pressure Gauge with Brass Internals, 0-100 psi, 2-1/2\ Dial Display, +/-1.5% Accuracy, 1/4\ NPT Bottom Mount

Brass wetted parts for measuring non-corrosive liquid and gas pressure.
Circular dial is filled with glycerin and enclosed in a stainless steel 304 case for corrosion resistance.
Measures pressure with single (psi) or dual scale (psi/kPa)/(psi/bar)/(Hg. vacuum/kPa)/(Hg. vacuum/bar).
Display accuracy is + or - 2.5% of full scale value for the 1.5" (40 mm) and 2" (50 mm) gauges, and + or - 1.5% of full scale value for the 2.5" (63 mm) and 4" (100 mm) gauges.
Lower mount or center back male connection with 1/8.

... have strong corrosion resistance and tightness, and will not easily break. The refrigerant gauge is also equipped with 3 standard test hoses (1.5m) and a portable toolbox, which is convenient for the storage and carrying of the meter..
2.【Refrigeration Gauges for Double Pressure and Dual Temperature Measurement】The digital HVAC gauges can measure double pressure (gauge pressure) at the same time, as well as dual temperature measurement, with automatic multi-unit pressure conversion, automatic conversion of temperature Celsius / Fahrenheit, to facilitate different needs. Note: Please make sure that the temperature sensor clip is properly connected. A poor connection will result in an inaccurate reading of the value..
3.【HVAC Gauges with High-Precision Data Unit and Refrigerant Database】The HVAC manifold gauge built-in 32-bit digital processing unit and a high-precision data acquisition unit, high data and stability. The a/c manifold gauge set built-in 89 kinds of refrigerant pressure-evaporation temperature database, also calculate the subcooling superheat, to facilitate the direct reading of operating process data. Also, it tests the percentage of vacuum me....

Creates unrestricted flow by securely and confidently removing valve cores.
Built-in rare-earth magnet keeps the plunger conveniently stored for fewer lost parts on the job.
1/4" side flare to easily connects with a vacuum gauges.
Vacuum tested to 20 microns and 800 PSI working pressure.

1.[ For Refrigeration Equipment ]：The digital manifold hvac gauge is used to assist in the installation, testing and maintenance of refrigeration equipment such as air-conditioning and cold storage. It has outstanding features such as dual pressure test, dual temperature test function, digital reading, multi-unit switching, and built-in refrigerant database. Note: The temperature measured by the device is allowed to have a deviation of 3% from the actual temperature..
2.[Built-in Refrigerant Database ]：Digital manifold gauge set hvac has a built-in database of 89 refrigerant pressure-evaporation temperature. Before you fill refrigerant, you can set different types of working refrigerants according to the car needs to fill. Digital manifold gauge set also calculates the degree of subcooling and superheat, which is convenient for direct reading of the operating process data. It also tests the percentage of vacuum measurement,pressure leak measurement..
3.[ Dual Pressure & Dual Temperature Measurement ]：The digital manifold gauge set can measure dual pressure and dual temperature simultaneously to help you determine the cooling capacity of your refrigeration system. The lower the evaporating (Ev)/condensing (Co) pressure and temperature, the more ef....
