Commercial Pressure Gauge, Dial Size 4″ (100 mm), Range 0 to 14 Kg/Cm2 with Dual Scale of 200 PSI, Surface Mounting Bottom Entry, 3/8″ BSP (M) Connection, MS Case & Brass Internals, Accuracy 2% FSD

Description

Experience accurate, durable, and cost-effective pressure measurement with the “Ji” Japsin Instrumentation Commercial Pressure Gauge. Engineered to deliver consistent readings in light to medium-duty industrial and commercial applications, this pressure gauge is tailored for environments that demand reliability without compromising affordability.

Featuring a large and legible 4″ (100 mm) dial, this gauge offers ease of readability in all operational conditions. It measures pressure in both kilograms per square centimeter (Kg/Cm²) and pounds per square inch (PSI) with a dual scale that ranges from 0 to 14 Kg/Cm² and up to 200 PSI. Housed in a powder-coated mild steel (MS) case and equipped with brass internals, this commercial gauge is designed to withstand typical mechanical wear while delivering dependable performance.

Designed for surface mounting with a bottom entry, and featuring a 3/8″ BSP male connection, this gauge is ideal for monitoring air, water, oil, and other non-corrosive gases or fluids in HVAC systems, compressors, pumps, pneumatic setups, and general commercial processes.

The “Ji” Japsin Commercial Pressure Gauge with a 4″ dial is a trusted companion for routine pressure measurement needs in workshops, production floors, utility rooms, and field environments. This robust device merges practical engineering with economical value, making it ideal for industries where basic monitoring is essential, but high-end specifications are not mandatory.

Constructed with a powder-coated mild steel case, the gauge offers satisfactory protection against typical atmospheric conditions and light industrial dust. The brass internals—including the Bourdon tube and movement—ensure that the gauge is non-reactive to common working fluids such as air, water, oil, and other inert gases. It is not recommended for aggressive chemical environments; for such use, a stainless steel version is available.

Its dual scale provides users with simultaneous readings in Kg/Cm² and PSI, reducing the need for conversions and enabling fast decision-making. The range of 0–14 Kg/Cm² makes this gauge particularly suitable for pneumatic systems, water distribution setups, hydraulic circuits, and general service utilities that operate within moderate pressure levels.

The bottom entry configuration and surface mounting design allow seamless installation in panel boards, manifolds, and horizontal pipe systems. The 3/8″ BSP male connection is a standard size, ensuring wide compatibility across various plumbing and industrial equipment.

Applications:

• HVAC Systems – Ideal for monitoring air pressure in heating, ventilation, and cooling systems.

• Pumps and Compressors – Suitable for oil and water pumps and compressed air systems.

• Workshops & Fabrication Units – Monitor pressure in pneumatic tools and equipment.

• Agricultural Equipment – Useful in irrigation systems and pressure-regulated spraying equipment.

• General Utilities – Air lines, water lines, and small-scale hydraulic equipment.

Material and Build Quality:

• Case Material: Mild Steel (MS) – Powder coated for corrosion resistance in normal atmospheric conditions.

• Wetted Parts: Brass – Compatible with non-corrosive fluids and gases.

• Dial Material: Aluminum with high-contrast markings for easy visibility.

• Pointer: Balanced black aluminum pointer ensures accurate pressure indication.

• Window: Clear polycarbonate – impact-resistant and durable.

This gauge features a bottom entry and is intended for surface mounting, making it ideal for wall or panel installation. The 3/8″ BSP (M) threaded connection offers a secure, leak-resistant fit into compatible systems. It can be installed using standard tools without the need for specialized mounting accessories.

To ensure maximum life and performance, avoid installing this gauge in environments with high vibration, excessive pulsation, or corrosive chemicals unless protective accessories such as snubbers or isolators are used.

Maintenance & Safety Tips:

• Periodically inspect the dial for signs of pressure spikes or pointer bounce.

• Avoid exposure to corrosive chemicals or direct water splash unless the gauge is housed in an enclosure.

• Replace the gauge immediately if you notice fluid leakage or inconsistent readings.

• Use thread sealant tape sparingly to avoid contamination of the internals during installation.
