Aalborg model G gas proportioner meters
RM 0.00
Description
model G gas proportioner meters
Blending two or three gases in homogeneous infinitely variable concentrations directly at the end use point, this model G gas proportioner is unsurpassed in convenience and economy. Gas proportioners pay for themselves since they eliminate the need for expensive custom blended gas mixtures. They lend flexibility and economy to the utilization of component gas cylinders and “piped-in” supply lines.
Features
- blending of two or three gases with gas proportioners obviates the need for:
- ordering fixed gas mixtures
- contamination from reusable gas cylinders
- potentially inaccurate mixtures by gas suppliers
- rib-guided or fluted metering tubes facilitate stable/accurate readings
- magnifier lens in front shield to enhance reading resolution
- interchangeability of flowtubes and floats
- OPTIGRAD™ scales minimize parallax and eye fatigue
- simple means of panel mounting
