More About This Item

The Traceable® 4199TR is designed to provide reliable atmospheric pressure measurements in a convenient analog format. The instrument features three easy-to-read scales that allow users to view pressure readings in millibars, inches of mercury, or millimeters of mercury, making it suitable for a wide range of scientific, industrial, and educational applications.

An adjustable pointer can be positioned alongside the current reading to provide a visual reference for monitoring pressure increases or decreases throughout the day. This feature makes it easy to identify changing weather conditions or environmental trends at a glance.

The barometer is housed in a corrosion-proof nickel-chrome case designed for durability and long service life. Included mounting accessories allow the instrument to be displayed on a wall or positioned on a desk, bench, or workstation for convenient observation.

Each unit includes an individually numbered Traceable® Certificate documenting traceability to SI units through NIST or other recognized National Measurement Institutes (NMIs). This certification supports quality assurance programs, research applications, and documentation requirements while eliminating the need for separate calibration services. Guaranteed to have at least one year of calibration remaining on the certificate.
