Whether you need gauges within your industrial or manufacturing process or to take measurements out in the field, our digital vacuum gauges get the job done. Our products give contractors and technicians the confidence they need to complete any task on hand while offered at competitive prices. So, its pressure range, 10+5 torr has the same value as its dynamic range and this device might be looked on as limited by its pressure range. In the words of a famous philosopher, it all depends on what you mean by “best.”

Cold Cathode

Best practices for mounting gauges. Differential pressure gauges (analog and digital) measure and control pressure drops across filters, strainers, separators, valves, and pumps. Browse our collection of Micro gauges from notable brands, including Bullseyes, AccuTools, Supco, Testo, Fieldpiece, NAVAC, Appion, and more. The PGF series are 2.5“ dial gauges with a ±3-2-3% accuracy, liquid filled, and leak proof for superior performance in applications with high vibration, pulsation, and shock. consistent chemical resistance in the wetted area

Pirani

You will also find a wide range of sensor tubes, including piezoresistive, convection pirani, and thermocouple, and gas-independent capacitance manometers.

The included PC FieldLab Desktop software can be used for calibration, testing and live viewing of pressure.

Our gauges utilize a bourdon tube design.

Proper measurement is critical to ensuring the best product quality and optimum energy efficiency. But each sensor head operates over a dynamic range of 10+4. As the system pressure varies, the bourdon tube contracts and operates a mechanism which rotates the pointer over a graduated scale calibrated in inches of mercury.

Cold Cathode

Ionization

These are production duty gauges made to withstand the vibration and corrosive effects common with production duty equipment.

For example, the most common type of Bayard-Alpert gauge (BAG) will operate up to 10-4 torr and down to ~10-9 torr.

3 inch thread mount pressure gauge. Capacitance Diaphragm.

By contrast, a capacitance manometers have a useful range that spans from perhaps 25,000 torr to 10-5 torr. Shop equipment that is accurate and easy to read. By using tools that have several advantages over competing products, you can ensure you are using top-choice items that can get the job done. Pressure gauges and vacuum gauges allow users to monitor the pressure of air and noncorrosive fluids in pumps, filters, compressors, and regulators. open interface architecture for system integration

Boiler gauges measure both the temperature and water pressure in boilers.

Gauge Controllers

Are you measuring your vacuum pressure?

There are many different types of gauge and each type has a specific pressure range, or dynamic range limit. We are frequently asked, “Which is the best gauge for my application?” High Vac Depot is here to provide the best selection of reliable and efficient tools that promote productivity and safety for contractors and technicians. Some of the instruments in this collection offer wireless Bluetooth capability with the precise control and remote monitoring you need. The first consideration is the pressure range you wish to measure.

Gauge Cables

The DPG8001 series have a durable NEMA 4X case and protective boot, and min/max readings, zero function, and selectable units with ±0.25% accuracy for general purpose uses.

Pirani

The total range of scientifically useful vacuums extends from approx. 1000 mbar (atmospheric pressure) down to 10-12 mbar – the ultra-high vacuum range.

4-1/2 inch lower connection pressure gauge. Thermocouple alloy & copper pin/socket options available. Regardless of your industry, we have the tools and instruments you need to monitor pressure for optimum performance. The LC10 has the ability to show High and Low pressure values on-screen, change between 15 different engineering units or add custom engineering units.

Our gauges are HIGHLY ACCURATE, barometrically independent, aneroid (capsule) type (Bourdon tube for 0-1200mm), ABSOLUTE pressure gauges. A physical measurement of the whole vacuum/pressure range is not necessary. To ensure high accuracy, all bearings are set in jewels, which provide exceptionally smooth pointer movement. Combination Gauges.

Convection

That is, to measure any pressure within the complete range requires a number of sensor heads because the dynamic range of each head is less than the pressure range.

Key takeaways

Our vacuum gauges, transducers, sensors and controllers are based on multiple pressure measurement technologies including Convectron®, Micro-Ion®, MicroPirani™, Piezo hot and cold cathode, Stabil-Ion®, and MEMS-based multi-sensor technology. Thanks to our excellent supplies and impeccable support and service, experience a smooth and delightful shopping experience while shopping for the gear you require. In this case of direct (or absolute) pressure measurements, the readings obtained through the vacuum gauge are independent of the type of gas and the pressure which is to be measured. View various kits and individual parts from our lineup today such as the Rugged Weatherproof, HVAC Micron Gauge, TruBlu Professional Kit, Dual Port Wireless Vacuum Gauge, and more. Factors to consider when selecting the correct sensor.

The LC10 is a robust device that measures and displays pressure readings on a large, backlighted screen.

Learn about direct, indirect, and absolute gauge measurement. Gauge Controllers. Each gauge has a dual absolute pressure scale, reading in both millibars (mbar) and Torr (mm Hg). Online shopping for Vacuum Gauges – Pressure & Vacuum Gauges from a great selection at Industrial & Scientific Store.

These systems are also offered in combination as multi-range vacuum gauges for covering multiple measuring ranges.

Convection

Gauge Cables

Particular sensors and gauges must be used for parts of the whole range – rough, high and ultra-high vacuum. Combination Gauges. Our products are characterized by: The PX480 series are compact and rugged with vacuum, absolute, and gauge pressure, current and voltage outputs to integrate with a variety of industrial and OEM applications.

plug and play – tailor-made and easily configurable components due to VACUU·BUS®

Best of all—we calibrate all our digital vacuum gauges against NIST standards. Through offering a trusted line of equipment, many can look to us for the supplies they can rely on for numerous projects and jobs. Supply yourself with the essential tools you need at High Vac Depot today. The pressure range is approx. from 1000 mbar (atmospheric pressure, 750 Torr) to 1 mbar (0,75 Torr). Each of our electronic vacuum measurement tools allows for heat transfer through conduction with rugged, durable construction that is built to last.

Each gauge is individually calibrated at every point on both increasing and decreasing pressure.

At common so-called mechanical vacuum gauges (BOURDONVAC, DIAVAC, capsule vacuum gauges) the pressure is determined directly by recording the force acting on the surface of a diaphragm.

We offer a comprehensive range of electronic measuring instruments for laboratory and industrial use, as well as controllers for rough and fine vacuum to regulate from atmospheric pressure down to 10-3 mbar.
