Overview
The Ntron Yellow Box is a compact, robust, transportable oxygen analyzer for high-accuracy oxygen measurement and verification of primary instrumentation. Built on the same engineering as the Microx, it is available as model 100, 200 or 300 with zirconia sensors covering ppm and % ranges, and an in-built flow indicator.
Working Principle
Long-life, quick-response zirconia sensors measure O2 in a positive-pressure sample (internally regulated to 0.3 barg, 250 ml/min). Each analyzer channel has its own 4–20 mA output; an analyzer select switch and the sample-out flow meter are built into the case.
Applications
Benefits
- Line-powered verification of primary O2 instrumentation
- One case covers ppm and % measurement
- Transportable for field checks
