Model 921A Combustible Gas Meter - Overview

Overview
The Arbiter Systems Inc. Model 921A Combustible Gas Meter is a rugged instrument that measures total combustible gases (TCG) in oil-filled transformer nitrogen gas blankets, TCG measurements have been shown to be good indicators of transformer health.

The supplied cylinders of instrument Air, Zero Grade Nitrogen and 1% Methane in Nitrogen calibration gases support field calibration, after which TCG measurements are virtually automatic. The Model 921A also has a built-in gas pressure sensor. By connecting the gas sampling hose to the PSI port and pressing PSI, the blanket fill gas pressure can be accurately measured.

The Model 921A is provided with a hard-sided transit case, along with instrument air, nitrogen, and 1% calibration gas cylinders and all necessary regulators and accessories.
