| MeasureNet is a radical
departure from conventional data collection performed with PC-based
interfaces. The MeasureNet system
is the only networked
electronic data collection system designed and manufactured for the
science teaching laboratory that provides high-quality data collection
and intuitive operation without the cost and maintenance of
bench-cluttering stand-alone PC's. These elements combine to provide
you with a one-of-a-kind lab management solution.
A single MeasureNet Network as represented in the
adjacent diagram can replace up to 12 stand alone PCs and their
PC-based interfaces. High-quality 24-bit A/D measurement occurs at
individual work stations and via a shared diode array visible nearer or
UV-vis spectrometer. Students receive immediate graphical feedback of
the experiment at their stations and can choose to print and/or save
their results.
Additionally, the single MeasureNet Network PC can be
used to shunt data to MeasureNet's online data center for storage and
further analysis outside the wet lab. Alternatively, the single
MeasureNet PC can also become a node on a departmental local area
network (LAN). Existing PC resource rooms can be used to open and
analyze collected data. In these ways, departments can avoid
replication of pre-existing PC resources in departments, school
libraries, student homes, and dorm rooms. Data aggregation for
collaborative and discovery exercises is conveniently facilitated by
the network and its single PC.
The documented maintenance, PC-replacement, and energy
savings of the network present departments with a cost-effective option
to PC-based interfaces. Download,

Measurements occur at individual student stations and shared
spectrometer, but are typically processed and stored by Network
Controller. The reliable controller and its software are the heart of
each MeasureNet network supporting between one and twelve data stations
and a diode-array spectrometer. Network software provides probeware
functionality and is easily upgraded at the controller via a single
PCMCIA card, not at the workstations themselves. The network software
presents probeware and collection options using a menu-driven
hierarchical menu system. MeasureNet's intuitive interface takes
minutes, not lab periods, to learn. |

The Network's stations share a single diode-array Visible-Near IR
(350-1000 nm, 1 nm resolution) or UV-vis (200-850 nm, 1 nm resolution)
spectrometer. Students efficiently perform scanning at the spectrometer
but return to their individual stations for viewing preliminary
results. The spectrometer is equipped with a tungsten-halogen light
source (Visible) or tungsten-halogen deuterium lamp (UV-vis) for
absorption experiments. The spectrometer's fiber optic cable can be
detached for mounting in a ring stand for emission scans of gas
discharge tubes, overhead lights, or a variety of flame emission
experiments. This powerful and efficient shared utilization feature
found in no other conventional PC-based spectrometer or data collection
interface.

MeasureNet's PC monitoring software provides you the ability to manage
your lab more efficiently. Along with printer interfacing and
storing/transmitting data sets, Instructors can view the network in use
and graphically examine student collection activities as students print
or save their data.
The software also provides real-time
point-by-point monitoring during temperature vs. time, pH versus time,
and mass versus time collections. Combined with an LCD projector, this
makes an effective teaching tool for sharing student collections with
an entire lab class. In time-sensitive environments, the software
enables instructors to provide assistance where needed, when needed.
MeasureNet's PC monitoring software also features
an interface to administer pre-lab quizzes. Results can be immediately
tabulated and student preparedness for the day's lab determined. Tools
are provided to adjust spectrometer settings and shut down power to
network components.

A MeasureNet Network provides flexible output, storage and analysis
options. Each network supports just a single high-speed inkjet or laser
printer for output of category-leading resolution and clarity. Only one
printer is needed for an entire 12-station network, saving your
department time and money on maintaining multiple printers.
MeasureNet's unique system of "print codes" gives
additional options for performing basic analysis on plots of pressure
volume, absorption spectroscopy, and titrations. When more analysis is
needed, data sets can be stored on the single PC's hardrive for
distribution over your department's LAN or to MeasureNet's web-based
data center. Saved as tab-delimited .txt files, you can import them to
almost any analysis program or use MeasureNet-provided MS Excel
Workbooks. The files are cross platform ready as well, usable in
Windows or Mac OS environments.
