This pneumatic comparison test pump is designed for testing pressure measuring instruments against master test instruments. This cost effective instrument provides precise control for important calibration requirements and include many features found in our popular line of pneumatic deadweight testers.

Key features
• Dual pressure/vacuum capability
• Bench mount design
• Built-in handpump as pressure/vacuum source
• High quality needle valve for fine control
• Test port adapters that require no PTFE tape or wrenches

This versatile instrument provides calibrations from 1-30 inHg vacuum (0.03-1 bar) and 3-500 psi (0.2-35 bar) in one extremely accurate yet easy to use primary standard. A selector valve converts the unit from pressure to vacuum mode without the need to exchange pistons. Units are manufactured to the highest standards with certified accuracies traceable to International Standards Laboratories such as the National Institute of Standards and Technology (NIST). These piston/cylinder type pneumatic standards provide excellent stability, repeatability and accuracy. An optional built-in hand pump can be added for both pressure and vacuum generation.

Key features
• 0.015% of reading accuracy standard (0.008% optional)
• 1-30 inHg vacuum (0.03-1 bar vacuum)
• 3-500 psi (0.2-35 bar) pressure
• inH2O and mbar ranges available
• Series 3 non-magnetic stainless steel weights
• Units can be trimmed to local gravity FOC

The UT220 is a 1999 count AC&DC digital clamp meter that can ensure stable performance, higher degree of safety and reliability to users. It is designed with over-load protection for all ranges, perfect for all professionals measuring currents up to 2000A.



Notes

• Battery not included

• Be aware of voltage easily - the tip glows red and a beeper sounds when voltage is detected

• Continuous self-test so you always know it’s working

• Voltage detection range for wide application use - 90 V to 1000 V AC or 200 V to 1000 V AC

• Audible/Silent mode for added convenience
