PM26・PM43 Liquid Column Manometers
PM26・PM43 Liquid Column Manometers
The pressure is measured based on the height of a liquid column (water column or mercury column) in a glass tube. The reading precision was improved by increasing the inside diameter of the glass tube. These manometers can be used as in-house pressure standards.
Feature
・A model with a high precision scale for calibration of high-pressure pressure gauges is also available.
・A vernier type which allows pressure reading up to 1/20 scale is also available (Vernier type has a
high accuracy pressure scale.)
・Thicker inside diameter of the glass tube (from 6mm dia. to 8mm dia.) has improved the accuracy of liquid level
reading.
・The PM43 pressure controller has a built-in manual pump for fine adjustment which ensures better pressure
control than conventional products.
・An electrically driven vacuum pump unit is available. Contact NKS if required. (Model No.: XJ26-111)
・Pressure standard inspection
・JCSS Calibration Certification
・General test report available (PM26 only)
