PASCO PS-3215 Product Manual

Wireless Colorimeter and Turbidity Sensor
About the Product
The colorimeter simultaneously measures the absorbance and
transmittance of six different wavelengths. The sensor can be used
to study Beer's law (absorbance versus concentration), enzyme
activity, photosynthesis, and the rates of chemical reactions
(absorbance versus time). The colorimeter is now calibrated to read
concentrations directly from our ezSample Snap Vial test kits.
The sensor also functions as a turbidimeter for water quality
analysis. Rather than measuring transmitted light, the turbidity
sensor measures light scattered at a 90 degree angle from the
sample. Turbidity level (cloudiness) of water samples is measured in
nephelometric turbidity units (NTU).
What's Included
Wireless Colorimeter and Turbidity Sensor
2x Cuvette Rack
4x Cuvette with Cap, smooth
6x Cuvette with Cap, lined
Ampoule Cap
100 NTU Calibration Solution
Micro USB Cable
2x Label, 100 NTU Cuvette (not shown)

Required Items
• SPARKvue or PASCO Capstone Software
PASCO software is required for data collection and analysis
Required Items for Water Quality Measurements
• ezSample Snap Vial Test Kit
Chemical analysis of water samples requires an ezSample kit
for the chemical being tested. Kits are available for testing
Ammonia, Chlorine, Iron, Phosphate, and Nitrate. Search for
"ezSample" at pasco.com to purchase the kits. (Note that
other ion test kits do not require a colorimeter to determine
concentration.)
Wireless Colorimeter and Turbidity
Components
USB Port
Use with the USB cable to connect to a USB wall charger to charge
the battery. Connect to a USB port of a computer or mobile device to
send measurement data to software (iOS devices not supported).
Turbidity Sensor
Consists of a photodiode that measures the amount of light
scattered by a test sample at 90 degrees. When using or calibrating
this sensor, ensure that you are using a smooth cuvette.
Power Button
Press and hold for 1 second to turn the sensor on or off.
Light Source
Consists of a white LED for Colorimeter measurements and an
Infrared LED for Turbidity measurements.
Test Chamber
Insert a cuvette containing a test solution or an ezSample Snap Vial
ampoule. Keep out ambient light by closing the cover when using
cuvettes or covering ampoules using the Ampoule Cap. (If the
Ampoule Cap is lost, cover the ampoule with a crupled paper towel
or small cloth instead.)
Colorimeter Sensor
Consists of a spectral sensor capable of detecting six wavelenths of
light. The sensor measures the intensity of light transmitted through
a solution in the test chamber. When using this sensor, ensure that
you use a lined cuvette with the smooth sides between the light
source and sensor (left to right).
