Description

Low Range Handheld Pneumatic Vacuum Cum Pressure Calibrator | –0.95 to 7 Bar | Japsin Instrumentation

Pressure calibration plays a critical role in ensuring the accuracy and reliability of industrial process control systems. Whether in manufacturing plants, HVAC systems, power generation facilities, refineries, or laboratory environments, technicians require a compact and precise tool to generate controlled pressure or vacuum on the spot. The Japsin Instrumentation Low Range Handheld Pneumatic Vacuum Cum Pressure Calibrator (–0.95 to 7 Bar) is engineered exactly for this purpose.

Designed for real-world field conditions, this calibrator provides technicians with the ability to quickly generate pressure or vacuum without electricity, compressors, or bulky calibration rigs. It is entirely mechanical, portable, rugged, and built for long-term industrial use.

From troubleshooting a faulty transmitter to validating pressure switches, verifying gauges, or performing regular maintenance checks, this handheld pneumatic calibrator is an indispensable tool for instrumentation engineers and maintenance technicians across industries.

Dual Functionality: Vacuum + Pressure in One Device:

One of the standout capabilities of this calibrator is its ability to produce both vacuum and pressure using a single handheld pump. This dual capability eliminates the need to carry two separate devices.

Vacuum Generation (–0.95 bar):

• Ideal for calibrating vacuum gauges

• Leak testing

• Generating negative pressure

• Testing suction systems

• Validating vacuum switches

It can reliably pull vacuum down to –0.95 bar (near perfect vacuum), making it suitable for both industrial and laboratory vacuum calibration tasks.

Pressure Generation (Up to 7 bar):

• Pressure gauge calibration

• Transmitter verification

• Switch testing

• Pressure line checking

• Valve & regulator testing

The ability to generate positive pressure up to 7 bar makes it suitable for a wide variety of pneumatic system applications.

This combination of vacuum and pressure in one handheld device greatly enhances productivity and efficiency in calibration work.

Precision and Stability for Professional Calibration Tasks:

A calibration pump is only useful if it can generate stable pressure. This is where Japsin’s engineering expertise stands out. Every unit is manufactured with precision machined internal components and sealed with high-grade O-rings, ensuring minimal leakage.

The integrated fine adjustment control valve allows the technician to precisely tune the pressure to the exact point required. This precision is essential for:

• Gauge calibration

• Transmitter zero/span checks

• Switch setpoint verification

• High-accuracy instrumentation testing

Even the smallest pressure adjustments can be made smoothly and gradually, making it ideal for sensitive equipment.

Rugged, Industrial-Grade Construction:

Industrial environments demand tools that can withstand tough conditions. This calibrator is built using:

• High-strength anodized aluminum

• Stainless steel fittings

• Industrial-grade seals and O-rings

• High durability polymer handles

The result is a tool that can endure:

• Continuous daily field use

• Rough handling

• Extreme temperature variations

• Dusty and industrial plant environments

Despite the rugged construction, the device remains lightweight and fully portable.

Ergonomic and Technician-Friendly Design

A technician may use a pressure calibrator for long hours during inspections or maintenance cycles, so comfort matters. This calibrator is ergonomically designed with:

• Anti-slip handle grip

• Low-force squeeze mechanism

• Balanced weight distribution

• Smooth pump operation

The easy-to-hold design reduces hand fatigue and makes extended calibration sessions more efficient.

Leak-Free Performance for Stable Calibration:

A common problem with cheaper calibration pumps is air leakage, resulting in unstable pressure output. This makes calibration inaccurate and extremely frustrating.

Japsin’s calibrator is engineered with:

• Precision-machined seals

• Advanced leak-proof valve design

• Industrial air tightness standards

This ensures:

• Pressure stability over long periods

• Minimal drift

• Reliable calibration outcomes

This leak-free design makes it ideal for:

• Onsite maintenance teams

• Third-party calibration labs

• Quality assurance teams

• Process instrumentation engineers

Compatible with a Wide Range of Instruments:

The calibrator supports standard process connections (1/4” BSP or NPT), making it compatible with almost all industry-standard instruments, including:

• Analog pressure gauges

• Digital pressure gauges

• Smart pressure transmitters

• Differential pressure indicators

• Pressure switches

• Sensors

• Calibrators

• Testing rigs

This universal compatibility ensures seamless integration with existing equipment.

Portable Calibration—Anytime, Anywhere:

One of the strongest benefits of this unit is its portability. No electricity required. No compressor. No power cables.

Simply take it to the field, connect your instrument, and generate pressure instantly.

Ideal for:

• Field inspections

• Onsite repair jobs

• Testing remote installations

• Laboratory test benches

• Service vans

• Shutdown maintenance

This portability significantly reduces downtime and makes calibration quicker and more convenient.

Safety & Overpressure Protection:

The calibrator includes a built-in pressure relief valve to protect technicians and instruments from accidental overpressure. This is especially important during sensitive transmitter or gauge calibration.

Safety features include:

• Controlled pressure release

• Relief valve protection

• Secure, leak-free fittings

• Smooth pressure rise

Technicians can work confidently without risking equipment damage.

Applications Across Multiple Industries:

This calibrator is ideal for:

1. Oil & Gas

• Pressure transmitter calibration
