neW goniometer<br />
$159<br />
Using a Goniometer and EKG sensor to measure<br />
joint angle and muscle activity<br />
orDer coDe<br />
gnm-bta<br />
the goniometer can be used to measure the dynamic<br />
motion of a limb during different types of physical<br />
activity.<br />
• a set of elastic straps are used to secure the sensor to<br />
the subject.<br />
• The lightweight and fl exible joint arms allow the limb<br />
to move naturally.<br />
• Use it with an eKg sensor to measure muscle activity<br />
during limb motion.<br />
• the sensor can also be detached from the base plate<br />
and fl exible arms so it can be used in a variety of STEM<br />
and engineering activities.<br />
range: 0 to 340° (±170°)<br />
resolution:<br />
12-bit (labQuest, labQuest Mini, labPro, go!link, SensorDaQ): 0.05°<br />
10-bit (cBl, cBl 2, nXt adapter): 0.12°<br />

vernier gPs sensor<br />
$64<br />
the Vernier global Positioning System (gPS) Sensor<br />
collects latitude, longitude, and altitude, right on your<br />
original labQuest* or computer.<br />
• See a real-time graphs of latitude vs. longitude, or<br />
export the data to various mapping programs, including<br />
google Maps or arcgiS.<br />
• connects directly to the USB port on a computer or<br />
original labQuest*<br />
Use gPS to enhance data collection:<br />
• Performing water quality tests at multiple sites? Record<br />
your location as you make measurements, and then<br />
map the data using logger Pro.<br />
• Studying acceleration in a car or train? Collect location<br />
information along with acceleration data and display a<br />
color-coded map.<br />
*Note: Not needed for LabQuest 2. LabQuest 2 has a built-in GPS sensor.<br />
Logger Pro combines GPS data and water quality<br />
sensor data.<br />
