Model T15v
Data Summary

A portable data acquisition tool
for measuring and recording low and mid-range environmental levels
of carbon monoxide and temperature

Examples of actual data gathered using this instrument series. These graphs use the Sense-Your-World! Software.

The Langan Model T15v CO Measurer is an integrated package that combines sophisticated software
with a reliable electronic instrument for measuring carbon monoxide to a high resolution at low levels.
The T15 has an electrochemical sensor optimized to observe carbon monoxide in the
0 to 200 parts per million (ppm) range with a resolution of 0.05 ppm (50 ppb).

The PEM includes field-tested data acquisition electronics, precision signal
conditioning and the highly regarded CiTiceL® Electrochemical Sensor.
Langan provided Software is used to read and reset the instrument, to display the results
in useful presentations and to translate data to other computers.
A digital display is built into the case. Batteries and interface cables come, as well.
It is delivered while operating. Open and measure what gas was observed during shipment!

The Model T15v is an evolution of the earlier Model T15 or T15d CO Measurer which used
the DataBear Measurer for data acquisition. The new T15v moves to 12-bit resolution,
more than double nonvolatile memory, and ten-year battery support.

One side of the T15v has all functions: a toggle switch for the digital display (to 0.1 ppm CO)
allows a momentary or 'on' display. A modular line plug is the point of connection for downloads.
Two potentiometers can be accessed to change the zero level or gain of the CO sensor during calibration.
