EnCal 3000 Chromatograph

The EnCal 3000 by Honeywell Elster® is a gas chromatograph analyzer specifically designed for natural gas energy measurements.

Honeywell Gas Chromatograph

This advanced analyzer uses chromatography components based on state-of-the-art Micro-Electro-Mechanical Systems (MEMS) and capillary column technique that provides accurate and highly dependable results. The Encal 3000 features a compact, explosion-proof design and includes analytical hardware, stream selection, and necessary electronics for standalone operation.

In natural gas energy measuring, calorific value is a critical component that determines the energy content, along with volume, pressure, and temperature. The Honeywell EnCal 3000 helps gas transmission and distribution companies, as well as end-users consuming large amounts of gas, accurately measure of single gas components, which is essential given that wrong measurements can directly impact the bottom line.

Features & Benefits


The EnCal 3000 analyzer injects natural gas into a stream of carrier gas that continues to a column where the natural gas divides into its constituents. The separated parts then pass a calibrated detector, and collected data from the constituent's levels calculate the heating value/Wobbe-index/density of the natural gas.
