JWF offers a broad product range of calibration instruments for pressure, temperature and for electrical measured values.
JWF are the ideal partners for calibration solutions whatever level of accuracy that is required. We can offer single instruments through to fully automated calibration systems for the laboratory or production.
Our products include hand pumps, deadweight testers, portable calibrators, dry-well, calibration baths and other reference instruments.
Precision digital pressure gauges are suitable for stationary & mobile measurement and display of pressures. In addition, a digital pressure gauge can be used as a pressure reference enabling easy testing, adjustment and calibration of other pressure measuring equipment directly on site.
Hand-helds are portable calibration instruments for the accurate measurement and recording of pressure profiles. These are available with interchangeable pressure sensors with measuring ranges of up to 8,000 bar. Some instruments document calibrations in the internal memory, which can later be evaluated via PC software. Optionally, a calibration certificate can be generated with our calibration software WIKA-CAL.
The most accurate reference instruments for pressure calibration are Pressure balances, also known as dead-weight testers or primary standards. Mass pieces placed on the top of a piston-cylinder system are the source of a precisely defined force. By producing a certain pressure inside the pressure balance an equilibrium is achieved. The mass pieces, including the free-running piston of the piston-cylinder system, are floating, which results in a very accurate pressure at the test port.
Test pumps can be used as pressure generators for testing, adjustment and calibration of mechanical and electronic pressure measuring instruments through comparative measurements. These pressure tests can take place in the laboratory or workshop, or on site at the measuring point. Products from simple hand operated test pumps to bench mounted pneumatic or hydraulic test pumps are available.
Hand-helds are portable calibration instruments for the accurate measurement and recording of temperature profiles. They are particularly suitable as test instruments for a large variety of applications in the widest range of industries. Data recorded in the hand-held can be evaluated via PC software and a calibration certificate can be generated with our calibration software WIKA-CAL.
Calibration baths are electronic controllers which automatically, quickly and with the help of a liquid supply an accurate reference temperature. Due to the high reliability & accuracy they are particularly suitable as a factory/working standard for the automatic testing and/or calibration of the widest range of temperature probes − independent of diameter. A special micro calibration bath design enables on-site applications.
Portable temperature calibrators (dry-well calibrators) are electronic controllers which automatically & quickly produce an accurate reference temperature. Due to the high reliability, accuracy and simple operation, portable temperature calibrators are particularly suitable as a factory/working standard for the automatic testing and/or calibration of temperature measuring instruments of all types.
