Model 3010TBC

Oxygen Analyzer



​The Model 3010C Series BASEEFA/CENELEC approved, intrinsically safe trace oxygen analyzers are versatile, microprocessor based instruments used for detecting oxygen from 0-10 ppm to 100% in a variety of gases.


The series features a Micro-fuel Cell to measure oxygen in the 0-10 ppm to 100% range. The sensors set industry standards for accuracy, sensitivity and ease of use, and come with a one year limited warranty against defects in material and workmanship. Also, because every sensor is manufactured using stringent quality control procedures, the user is assured of outstanding reliability and optimum performance. The sensor is a sealed electrochemical device with no electrolyte to change or electrodes to lean, making it maintenance free. The sensor is specific to oxygen and can be used in a variety of background gases including hydrocarbons.


These units offer three dynamic, user-configurable ranges and can be calibrated at any range. Two fully programmable concentration alarms and relays provide the versatility to satisfy nearly any requirement.


Two standard 0-1 VDC outputs and two 4-20mADC isolated outputs provide both concentration and range identification. A bi-directional RS-232 serial interface is incorporated to relay information to a host computer for remote monitoring of zero and span calibration.

Split Architecture

These units are designed as “split architecture” instruments, meaning that a general purpose control unit for non-hazardous areas controls a specially designed analysis unit or “remote probe” that is CENELEC approved intrinsically safe for use in area classification EEXiallCT6, Zone 0. Simple menu choices, membrane command switches and dual displays make setup and operation clear and quick. The 3010TC series is constructed of high quality materials to insure long term, trouble free materials to insure long term, trouble free service.
