1.5 Accuracy and Response
The Model 3110XL provides monitoring accuracies of ±2% of full
scale or ±1 ppm, whichever is greater, at constant temperature.
With a sample flowrate of 1 SCFH, a 90% response can be
achieved in 10 seconds when analyzing in the percent range. The
response time on the 3110XL is limited by the filter setting.
1.6 Signal Output
This analyzer includes a 0-1 VDC output as standard. This signal is
suitable for driving external devices that have an input impedance of
10,000
Ω
or more. The signal output is available from a port on the rear
panel.
1.7 Range
The Model 3110XL has one user defined range extending from 0-2
ppm to 0-25% with a display resolution of 0.1 ppm when analyzing at
less than 1%. When measuring oxygen at levels greater than or equal to
1%, the display resolution is 0.01%.
1.8 Compact Packaging
The instrument is housed in 6 1/8" × 9 1/2" × 5 5/8" (156 × 241 ×
143mm) aluminum case that is equipped with a carrying handle and foot
pads.
