New laboratory pressure transfer standard

The model 745 it is designed to give extremely accurate pressure measurements with a resolution of 0.0001% and 0.008% full scale accuracy

ETL announces the availability of a new high accuracy pressure and barometric standard transfer unit.

Designated the model 745 it is designed to give extremely accurate pressure measurements with a resolution of 0.0001% and 0.008% full scale accuracy.

Incorporating the latest state of the art Digiquartz transducers, it is able to cover up to 25 absolute and gauge pressure ranges of up to 40,000 psi (276MPa), with unsurpassed accuracy, reliability and stability, says the company.

The 745 has a simple easy to read front panel and with a rear panel RS232 computer interface make this product the ideal choice for high performance calibrations.

The innovative 745 gives immediate readings of the pressure values in any of nine different user selectable engineering units.

All pressure readings are temperature compensated and linearised.

Other capabilities include tare functions, pressure and temperature units, resolution, sampling time, number of display units, communication settings, baud rate, and sensor address, and password that can be selected via the front panel menu.

Choices for the second line display include an analogue pressure bar graph, sensor temperature, rate of pressure change and stored text or external text.

Software is included to read and log data via the RS232 port.

The unit weighs only 1.8kg and is in a fully self contained CE marked case, and is powered from its AC adapter or for up to 20 hours by four AA cells.

This versatile product has applications in metrology, aerospace, meteorology, oceanography, energy exploration, reference barometers and laboratory instrumentation.
