neW vernier optical
do Probe
$379
the Vernier optical Do Probe makes it easy to measure
the dissolved oxygen concentration in water. Perfect for
the fi eld or for the laboratory, this plug-and-play probe
requires no calibration, no fi lling solution, no warm-up
time, and no stirring.

Use the original Dissolved oxygen Probe to determine the
concentration of oxygen in aqueous solutions.
• Built-in temperature compensation and a fast
response time.
• Includes zero-oxygen solution, two caps fi tted with
membranes, a 100% calibration bottle, and electrode
fi lling solution.

drop counter
Use the Drop counter with our ph Sensor, conductivity
Probe, or orP Sensor to easily perform conductimetric or
potentiometric titrations.
• Precisely records the number of drops of titrant added
during a titration, which is automatically converted
into volume.
• Includes a cable, Microstirrer (shown below), and
reagent reservoir.

dual-range
force sensor
our Dual-range force Sensor can be easily mounted on a
ring stand or dynamics cart or used as a replacement for a
hand-held spring scale. it has two ranges: ±10 n and ±50 n
and resolution of 0.01 n and 0.05 n, respectively.

See page 89 for more information.
air track adapter, orDer coDe ata-dfs, $55
allows the Dual-range force Sensor to be mounted on the
end of an air track for collision studies. compatible with
most air tracks. includes two magnetic bumpers.
force table adapter, orDer coDe fta-dfs, $29
Use your Dual-range force Sensor with your force
table for resolution of vectors experiments. includes
mounting clamp.
mass for dynamics cart, orDer coDe mass, $12
this 500 g steel block is a great accessory for newton’s
second law labs. it attaches to a dynamics cart and leaves
room for both a Dual-range force Sensor and
an accelerometer.
