The Model 3000PB is a versatile, microprocessor-based instrument for detecting percent oxygen in a variety of gases. It serves as a general purpose unit and has simple menu choices, membrane command switches and a large LED display to make setup and operation simple and fast.
Ambient Air Calibration
The high accuracy and fast response is only surpassed by its ability to calibrate without the assistance of support gases. The Micro-fuel Cell produces an output that is linear from 0% to 100% O2 enabling the use of ambient air for calibration. These units can also accommodate the use of span or zero gas when necessary. This unit also offers stainless steel sample tubing and a nylon cell holder
Convenient Outputs
Standard 0-1 VDC outputs are provided for oxygen measurements and range identification. An RS-232C serial port interface allows the user to introduce span and zero gases through a host computer.
Three Analysis Ranges
Three user-configurable ranges are standard, with excellent linearity precluding recalibration when changing ranges. Two fully programmable concentration alarms and relay functions provide the versatility to satisfy nearly any requirement. All features offer a sophistication that assure these instruments will provide years of service.
