## Overview

Pressure balances are the most accurate instruments available on the market for the calibration of electronic or mechanical pressure measuring instruments.

## Applications

- Primary standard for calibrating the pressure scale in a pneumatic range from -1 ... 120 bar [-14.5 ... 1,600 lb/in 2 ]
- Reference instrument for factory and calibration laboratories for the testing, adjustment and calibration of pressure measuring instruments
- Complete, stand-alone system, also suitable for on-site use

## Special features

- Total measurement uncertainty starting from 0.015 ... 0.006 % of reading
- Four different piston-cylinder systems available for ranges ±1 bar, 0.1 ... 7 bar, 0.2 ... 25 bar, 1 ... 70 bar and 1 ... 120 bar, or also for ranges in lb/in 2 and kPa
- Quick and safe replacement of the piston-cylinder system for measuring range changes via patented ConTect quick-release system possible
- Masses manufactured from stainless steel and aluminium, can be adjusted to local gravity
- Factory calibration included as standard, traceable to national standards; with UKAS calibration possible
