Dead Weight Tester Piston Type Pressure Calibrator 0-300kgf/cm² 0-30MPa 0-300bar Calibration Instrument

Product Introduction

The Hydraulic Piston Dead Weight Tester is a precision pressure calibration instrument with a range up to 300 kgf/cm² (30 MPa / 300 bar). It features a durable tungsten carbide piston and cylinder, integrated manual hand pump, and accuracy classes of 0.05%, 0.02% or 0.01%. Weights can be marked in kgf/cm², MPa or bar as required. Ideal for calibrating pressure gauges, transmitters, transducers and sensors in both industrial and laboratory environments.

Application Areas

• Calibration of analog and digital pressure gauges

• Verification of pressure transmitters and transducers

• Testing of pressure switches and sensors

• Industrial process control and maintenance

• Metrology laboratories and quality assurance centers

• Oil & gas, petrochemical, power and manufacturing industries

• Calibration service providers and third‑party testing labs
