Digital Vacuum Gauge: Yellow Jacket Evac 69047
A digital vacuum gauge is an electrical device that detects pressure below atmospheric pressure. Vacuum is the name for this form of negative pressure. HVAC service workers and maintenance managers use vacuum gauges to measure pressure in air conditioning and heating systems, steam condensers, and other equipment.
Digital HVAC gauges assess air-conditioning units and present the results in digital form, removing the need for complicated computations. They assess the systems for leaks and check the pressure. Regular diagnosis can aid in the prevention of future AC issues.
One of the popular and most trusted brands for HVAC equipment is Yellow Jacket. That's why it's no wonder that there are many professionals in the HVAC field that uses the Yellow Jacket Evac 69047.
Yellow Jacket Evac 69047 Digital Vacuum Gauge
The most precise and accurate vacuum gauge available is the YELLOW JACKET® eVacTM II Programmable Digital Vacuum Gauge. It's tiny, light, tough, and simple to use, making it perfect for any HVAC/R technician. Also, its programmability enables the evacuation of HVAC/R systems, including all sizes, without the need for human intervention.

Digital Vacuum Gauge
Micron gauges are a more exact and sophisticated digital approach to monitoring air pressure.
When should you use a vacuum pump and a pressure gauge?
The two most common applications are after installing an AC system and when the refrigerant is drained. Pulling vacuum inside the system provides negative pressure, which allows for the appropriate refrigerant charge. It also clears the system of vapour and debris.
How do you know if the HVAC system is vacuumed?
In a two-step method, you are employing a micron gauge. To begin, pull the vacuum to 1000 microns, separate the vacuum, and let the pump run for another 5 minutes. You might have vapour or a leakage in the system if the vacuum lowers dramatically. After pulling the vacuum to 500 microns in the second phase, your unit should be ready to charge with refrigerant if the leak rate is minimal.
Moreover, micron gauges come from several reputable companies, including Yellow Jacket and more.
Benefits of Digital Pressure Gauges
Durable
Extreme temperatures, dangerous circumstances, and regions subjected to significant mechanical vibration are not a problem for digital pressure gauges. They're often aluminium or stainless steel with thick, crack-resistant plastic coverings to safeguard them from shocks, drops, flying debris, and toxic chemicals. It has a design to endure misuse and to crack. As a result, they outlast analog gauges in durability and resistance to vibration and overpressure spikes.
Calibration
A calibrated digital pressure gauge maintains its calibration more consistently than an analog pressure gauge. Digital calibration is substantially more exact because it works with software.
Readability
Digital pressure gauges include a large, easy-to-read LCD with a clear readout. The majority of them also have a bright backlight. Taking data from an analog gauge usually necessitates interpreting the needle's position. Due to the obvious quick, at-a-glance nature of perceiving the needle on the dial, analog is sometimes favoured in some applications when you must collect readings from a distance or many pressure readings must be measured at once. Analog gauges, on the other hand, are frequently misread because of parallax mistakes. The dial seems to be at different positions depending on the angle the data is interpreted.

In the end, the type of gauge you employ will be determined by the requirements of your unique application. Analog pressure gauges will undoubtedly always have a place, but your pressure gauge is due for a digital upgrade if you rely on pressure measurement to conduct your work. At HVAC Shop, we can assist you in making that decision.
