|
| |
| Vernier : Conductivity Probe |
- 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 the migration of ions through membranes or to monitor changes in ion levels (such as HCO-3) 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.

| Vernier : Current and Voltage Probe System |
- This package consists of two voltage probes, two current probes and a dual-channel amplifier.
- You can monitor two currents, two voltages, or one of each.
- The probes were designed for battery and bulb experiments, but they are also great for low-voltage AC experiments.
- The voltage probes have a range of -6V to +6V. They have differential inputs and can be used independently, measuring voltage drops in a circuits.
- The current probes have a range of -0.6 amps to +0.6 amps and can be easily built into a circuit.

| Vernier : Dissolved Oxygen Probe |
- You can now make fast, accurate measurements of dissolved oxygen concentration in water samples using our new 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.
- This probe is great for biology, chemistry, ecology, or integrated science courses.

| Vernier : Dual-Range Force Sensor |
- Our most popular force sensor has two ranges: 10N or 50N.
- It can be easily mounted on a ring stand or dynamics cart, or used as a replacement for a hand-held spring scale. Use it to study friction, simple harmonic motion, impact in collisions.
- This force sensor is used for experiments in our physics and physical science lab manuals.
|
| |
|
| |
| Vernier : Gas Pressure Sensor |
- The new Gas Pressure Sensor is our first pressure sensor with enough resolution and range to work for all subject areas.
- It replaces both the original Pressure Sensor and the Biology Gas Pressure Sensor.
- Chemistry teachers will find that it has enough range for Boyle’s law experiments (0 to 2.1 atm), yet provides greatly improved resolution for vapor pressure or pressure-temperature experiments
- For biology teachers, the package now includes airtight tubing clamps for transpiration experiments, as well as special fittings for respiration experiments in small containers.

| |
| Vernier : Heart Rate Monitor |
- Use this sensor to monitor human heart rate at the ear lobe or fingertip.
- An ear clip sensor measures the change in light intensity as blood flows through the blood vessels.
- With each heart beat, the changing light intensity is measured, and the heart rate is determined.
|
| |
|
| |
| Vernier : Magnetic Field Sensor |
- This sensor, which uses a Hall Effect transducer, is sensitive enough to measure the earth's magnetic field.
- It can also be used to study the field around permanent magnets, coils, and electrical devices.
- Its two ranges are -3.2 to +3.2 gauss (-3.2 x 10-4 to +3.2 x 10-4 tesla) and - 64 to + 64 gauss (-6.4 x 10-3 to +6.4 x 10-3 tesla)
|

|
| |
| Vernier : Microphones |
- Our Microphone is a small box with an electret microphone on one end and an amplifier circuit inside.
- Use it to display and study the waveforms of sounds from voices and musical instruments.
- The MCA-CBL may be used for waveform monitoring or frequency counting.
- This microphone plugs directly into the CBL without the need for an adapter.
|
| |
|
| |
| Vernier : Motion Detectors |
- The Motion Detector functions like the automatic range finder on a Polaroid camera.
- This sonar device emits ultrasonic pulses and waits for an echo.
- The time it takes for the reflected pulses to return is used to calculate distance, velocity, and acceleration.
- The range is 0.4 to 6 meters.
|
| |
|
| |
| Vernier : pH System |
- Our pH System consists of a pH Electrode and pH Amplifier.
- The pH Electrode is a Ag-AgCl combination electrode with a range of 0 to 14 pH units.
- The pH Amplifier contains the signal-conditioning circuitry.
- The pH Amplifier and pH Electrode can also be purchased separately.
