The Ranarex is a fast-response, simple-to-operate portable gas gravitometer used to determine the specific gravity of a process gas in comparison to air.

The gravitometer offers multiple scales and field-proven accuracy within 0.05% of actual value over a specific gravity range of 0.52 to 1.90.
Free of span drift and with minimal zero drift, the Ranarex features a simple electro-mechanical design, simplifying both operation and maintenance. Jeweled pivots and permanently lubricated ball bearings minimize wear and virtually eliminate servicing.
Meeting the ASTM D1070 standard test method for relative density of gaseous fuels, the Ranarex offers a trusted solution for confirming process gas mixtures and quality in the hydrocarbon processing and natural gas industries.
