The 3190 analyzer proves that good things come in small packages. This microprocessor based unit offers high accuracy, easy use and all the standard features demanded by the end-user in a compact, budget priced design. Membrane command switches and a large, four digit LED display make setup and operation clear and quick.
Range Options
Depending on the application, this unit can be configured to use a Micro-fuel Cell sensor or zirconium oxide sensor, assuring the highest accuracy. With a long expected sensor life, the 3190 is as inexpensive to maintain as it is to purchase. It has a sensor failure alarm which takes away the worry and work out of the end-user’s hands. Two ranges are field configurable at 0-10 ppm and 0-1000 ppm with a 0-25% calibration range. Optional ranges can be set between 10 ppm and 10,000 ppm. Two programmable failsafe concentration alarms (one high and one low set-point) provide the versatility to satisfy nearly any requirement.
Outputs
A standard 0-10 VDC output provides range identification, while the oxygen concentration is output through 4-10 mADC negative ground and 0-10 VDC negative ground signals. An optional unidirectional RS-232 serial interface is incorporated to relay information to a host computer for remote monitoring of all functions. Configuration information and analysis results are as close as your personal computer.
Oxygen Sensor
An SP76 compliant oxygen sensor for trace and percent ranges is offered with the 3190. This can substantially reduce size, as compared to the alternative that requires discrete tubing cut and connected through fittings of various components like sensors, pressure regulators, valves, etc. Additionally, it is a building block, plug-and-play approach that makes even the most inexperienced assembler or designer an immediate expert.
