  • Manufactured in USA

The TRANSMAX EC single channel gas monitor for toxic or oxygen deficiency ap- plications delivers the latest in loop-pow- ered gas detection technology, reliability and ease of use.

Wide Variety of Available Sensors

The TRANSMAX EC supports all GDS Corp toxic sensors, including oxygen, hydrogen sulfide, chlorine, carbon monoxide and more (see chart on back). Disposable DELRIN sensor heads with integrated sensors make maintenance easy. Fault detection circuity constantly monitors sensor inputs for missing or faulty sensors.The TRANSMAX EC maintains a record of sensor calibration data and calculates and displays an estimate of sensor life remain- ing at the conclusion of each calibration cycle.

Advanced User Interface

The highly visible graphic LCD display shows the latest reading in large (0.6”) digits, engineering units and program- mable tag name. Flashing LEDs indicate alarm status, a unique feature among loop-powered devices. Activating the NEXT key switches to a trend screen that graphically displays alarm levels and a record of the most recent 30 minute trend. A built-in, prompted calibration procedure simplifies periodic maintenance needs.

An internal real-time clock and event log time-stamp up to 300 alarm events for later review. Taking advantage of the high-resolution graphic display, an easy- to-use menu-driven operator interface using magnetic keys eliminates all analog potentiometers and allows complete setup and calibration without opening the enclosure.

Enhanced Security

Three operational levels of security al- low the GASMAX EC to be fully field configurable, partially restricted or com- pletely restricted by way of user ID and access code.

Designed for General Purpose Areas

The TRANSMAX EC is designed spe- cifically for general purpose areas where highly reliable gas detection is required. The enclosure is rated NEMA 4X and IP66/67 for outdoor use. A splash guard is available for the sensor if directed water spray is expected.
