This is really three low-g accelerometers mounted at right angles and all placed in a small box. Use it for studying the complex motion of an amusement park ride, a bungee jumper, or simply a toss in the air. With most of our data collection programs, you can graph the magnitude of the total acceleration vector.

The CO2 Gas Sensor measures gaseous carbon dioxide levels in the range of 0 to 100,000 ppm. It has two settings: low range (0 - 10,000 ppm) and high range (0 - 100,000 ppm). This probe is great for measuring changes in CO2 levels during plant photosynthesis and respiration. With this sensor, you can easily monitor changes in CO2 levels occurring in respiration of organisms from crickets to humans! The CO2 Gas Sensor is easily calibrated using a calibration button. A chamber with probe attachment is included for running controlled experiments with small plants and animals.

This 4-wavelength Colorimeter is great for Beer's law experiments, determining the concentration of unknown solutions, or studying changes in concentration vs. time. The new design includes a one-button automatic calibration feature. Fifteen 3.5 mL cuvettes are included. A package of 100 replacement cuvettes (with 20 lids) is available.

This probe is great for environmental testing for salinity, total dissolved solids (TDS), or conductivity in water samples. Biology teachers can use this probe to demonstrate diffusion of ions through membranes or to monitor changes in ion levels in aquatic systems. Chemistry students can use it to investigate the difference between ionic and molecular compounds, strong and weak acids, or ionic compounds that yield different ratios of ions. The Conductivity Probe can monitor concentration or conductivity at three different sensitivity settings.

Use the Current Probe to measure currents in low-voltage AC and DC circuits. With a range of ±0.6 A, this system is ideal for use in most "battery and bulb" circuits. Use it with the Differential Voltage Probe to explore Ohm’s law, phase relationships in reactive components, and much more. Use multiple sensors to explore series and parallel circuits. It can also be used in electrochemistry experiments.

Use the Differential Voltage Probe to measure low-voltage AC and DC circuits. With a range of ±6.0 V, this system is ideal for use in most "battery and bulb" circuits. Use it with the Current Probe to explore Ohm’s law, phase relationships in reactive components, and much more. This differs from the Voltage Probe that comes with your interface in that neither clip is connected to ground. Use multiple sensors to explore series and parallel circuits.

Digital Control Unit
The Digital Control Unit
(DCU) gives you an easy way to use LabQuest, LabPro, CBL 2™, or original
CBL™ digital ports for exciting, do-it-yourself projects. It allows you
to provide useful current (up to 600 mA) for controlling electrical
devices. Using the DCU and simple programs, you can control motors,
lamps, LEDs, buzzers, stepper motors, and other DC devices. You can even
develop more elaborate projects, such as robots or automated scientific
apparatus. The most exciting DCU projects involve combining sensors with
control.
The Digital Control Unit is a small box with a short cable that plugs into a digital connector on the LabPro or CBL. An external power supply is required (not included). Most people will use the Vernier AC Adapter, but batteries or other power supplies can be used. Inside the DCU are visible LEDs that indicate the status of the six output lines. A socket is provided for connecting electronic devices that you build. A cable with bare wires on one end is provided for your first projects.

You can make fast, accurate measurements of dissolved oxygen concentration in water samples using our Dissolved Oxygen Probe. This probe has a range of 0 to 14 mg/L (ppm) of dissolved oxygen. It has built-in temperature compensation, which means you can do your calibrations in the lab, and then make measurements outdoors without having to recalibrate. The probe has a fast response time, reaching 95% of full reading in 30 seconds. This probe is great for biology, chemistry, ecology, or integrated science course.

Our new Drop Counter is an optical sensor that accurately records the number of drops of titrant added during a titration. The Drop Counter software can automatically convert the number of drops into volume. It will also record pH and temperature values and calculate the first and second derivatives of the pH for easy equivalence point determination. The Drop Counter can also be used for conductimetric or potentiometric titrations using our Conductivity Probe, Ion-Selective Electrodes or any electrode with a 0 to 5-volt output. You could even use it instead of a utility clamp anytime you need to hold an electrode in place. The Vernier Drop Counter can be used with your own buret or with the Reagent Reservoir included. This reservoir was designed to keep the drop size consistent and to make drop rate regulation simple and easy. In addition, we include a Vernier Microstirrer-a magnetic stirring paddle that slips onto the tip of your pH Sensor. When used with any magnetic stirring plate, the Microstirrer provides a faster response after each drop added. The Vernier Drop Counter includes a cable, Microstirrer, and the Reagent Reservoir.
