The Network Concept: Your Lab Management Solution
|
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
PCs. These elements combine to provide you with a one-of-a-kind lab management solution.

Quick View:
- 15 networked dum terminals serve as the student workstations.
- Students collect data with the probes attached to the workstations.
- The workstation provides graphical feedback about the collected data.
- Once data is collected, the central controller processes & stores it.
- Students can store data in a central database provided by measurenet.
- The computer attached to the network can monitor student progress in real time.

More About the MeasureNet Network Solution
 The Controller
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,
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 Student Workstation
Students work at compact measurement stations that combine a keyboard, graphical
display and measurement interface. Easy-to-use menus guide them through
experiments. Raw signals from each station's probes are digitized and sent to
the network controller. The controller immediately returns each result to the
proper station for digital and graphical display, tracking what is measured at
each station. With no memory or processor, the stations were designed as "dumb"
terminals for ease of maintenance and enhanced longevity.
Stations are hardwired to the network controller via simple U.S. telephone-style
wiring that utilizes RJ-11 connectors. This hardwired approach ensures better data
security and transmission reliability. Semi-permanent station-mounting and
hardwiring save lab prep time. MeasureNet interfaces don't require batteries or
need removal from storage drawers. Stations are assembled and quality-tested in
the United States and designed to provide a decade or more of reliable service.
They can be vertically mounted to reduce knock and spill risk and free benchtop
space for other critical tools.

 The Diode Array Spectrometer
The Network's stations share a single diode-arrayUV-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 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.

 The MeasureNet Software
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.

 Storage & Output
A MeasureNet Network provides flexible output, storage and
analysis options. Each network supports a single high-speed
inkjet or laser printer for output of category-leading resolution
and clarity. Only one printer is needed for an entire 15-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.
