Model 3300TB

The 3300 series of low cost, microprocessor-based instrument are specially designed to satisfy industry’s need for a simple yet highly reliable process analyzer. These units offer excellent accuracy, ease of use, high reliability, low maintenance and a variety of standard features usually found on more expensive instruments.

Multiple Configurations

This series is a cost-effective solution to many process applications. With three different sensing technologies to choose from and multiple design configurations, a customized unit for a given application is easily secured. Sensing ranges are varied based on the oxygen sensor and technology used. All units come with an auto-ranging capability and a 0-25% calibration range. Fully adjustable high or low concentration alarms provide the versatility to satisfy nearly any requirement.

Outputs for Data Transmission

A standard 0-10 VDC output provides range identification, while the oxygen concentration is output through 4-20 mADC negative ground and 0-10 VDC negative ground signals. An optional unidirectional RS-232 serial interface can be incorporated to relay information to a host computer for remote monitoring, making information and analysis results as close as a personal computer.

Sensing Technologies

The 3300 Series is available with three sensing technologies, each with their own benefit.
