Compatibility with most hydraulic and pneumatic test pumps ensures versatile calibration workflows. The rugged design and protective holster support field use and long-term durability, making it a popular choice for professional calibration tasks.
Fluke 700G31 Precision Gauge, 0-10000 psi
The Fluke 700G31 extends calibration capability to 0–10,000 psi with a bright backlit display for easy reading in dim environments. Like other 700G models, it’s designed to withstand demanding industrial use and integrates well with standard hydraulic and pneumatic test pumps. Its durable construction and protective holster help protect sensitive electronics during transport and storage, supporting consistent calibration performance over time.
INSTRUKART DPI-2300 Hydraulic Calibrator
The DPI-2300 is a dual-source hydraulic calibrator with both pressure and vacuum capabilities. It includes a built-in fine-adjust vernier and a needle valve for controlled pressure release. The selector valve allows seamless switching between vacuum and pressure generation, while ergonomic handles and adjustable stroke support comfortable, precise operation over extended calibration sessions. It’s suitable for calibration labs that require robust hydraulic testing capabilities across large pressure ranges.
Ace Instruments IK HPP-01 Differential Pressure Calibrator
This differential pressure calibrator is built for HVAC, laboratory, and room pressure monitoring applications. It emphasizes durable ABS construction and precise calibration performance. The large 120 mm display supports quick, at-a-glance readings, aiding technicians who need reliable differential measurements in confined spaces or busy environments. It’s well-suited for facility management and controlled testing environments where steady pressure differentials matter.
MEASUREMAN Digital Industrial Gauge 0-160 psi
The MEASUREMAN digital gauge covers 0–160 psi with a 0.2% full-scale accuracy and a 1/4″ NPT lower mounting. It includes a rubber over-molded housing for shock resistance and a large, rotatable LCD screen with bright backlight. Bluetooth connectivity enables data logging and remote monitoring, and the device supports multiple units for versatility across different systems. It’s a solid option for quick on-site checks and documentable readings in industrial settings.
Baker Instruments B1600 Squeeze Bulb Calibrator
The Baker B1600 uses a squeeze-bulb design with a pressure lock and relief via a check-valve thumb screw. It offers precise pressure generation within its range and is valued for its simplicity and portability in field calibration tasks. The design emphasizes ease of use for quick verification checks and educational demonstrations where a manual, tactile calibrator is advantageous.
Buying Guide: Key Purchase Considerations
When choosing a precision pressure gauge calibrator, consider these factors to match your needs:
- Measurement range and resolution: Match the instrument’s range to your typical calibration tasks. Higher ranges like 0–10,000 psi suit heavy hydraulic systems, while 0–160 psi covers many HVAC and general lab applications. Resolution (the smallest detectable change) directly affects calibration precision.
- Display readability: Bright backlighting and large digits improve readability in dim environments or busy workshops. Digital displays often offer unit switching and data logging, which aids traceability.
- Source and type: Hydraulic, pneumatic, differential, or digital gauges each serve different calibration workflows. Dual-source calibrators provide flexibility when both pressure and vacuum are required.
- Durability and form factor: Handheld, rugged enclosures with protective holsters or rubber housings withstand field use. Consider weight and ergonomics if you perform lengthy calibration sessions.
- Compatibility and accessories: Check pump compatibility, mounting options, and included fittings. Some models are designed to work with common test pumps and labs hardware.
- Connectivity and data handling: Bluetooth or USB data logging helps maintain calibration records and ensures traceability for quality systems.
- Calibration stability and accuracy: Look for manufacturer-stated accuracy (e.g., 0.001 psi, 0.2% FS). Stability under operating conditions affects long-term reliability.
- Maintenance and spare parts: Availability of replacement parts, seals, and service support can reduce downtime and extend device life.
