The following is a list of Vernier Probes at TuHS, how many of each, and short description of the probe’s function that can be used for labs and internal assessments.
Heart Rate- 8
The Hand-Grip Heart Rate Monitor is ideal for continuously monitoring heart rate before, during, and after exercise or while a person is stationary.
CO2 - 10
The CO2 Gas Sensor measures gaseous carbon dioxide in two ranges–0 to 10,000 ppm and 0 to 100,000 ppm.
pH Sensor - 7
Wireless pH Sensor - 3
Our general-purpose pH Sensor can be used across disciplines, including chemistry, biology, middle school science, and environmental science.
O2 Gas Sensor - 8
The O2 Gas Sensor can be used to monitor gaseous oxygen levels in a variety of biology and chemistry experiments. The sensor is intended for measuring gaseous, not aqueous, O2 concentration.
Dissolved Oxygen Probe - 2
Use the Dissolved Oxygen Probe to determine the concentration of oxygen in aqueous solutions in the field or in the laboratory.
Gas Pressure Sensor - 12
Use the Gas Pressure Sensor to monitor pressure changes of a gas in chemistry and biology experiments.
EKG Sensor - 2
The EKG Sensor measures electrical signals produced during muscle contractions, and can be used to make standard 3-lead EKG tracings or surface EMG recordings.
Spectrovis - 1
Use the SpectroVis Optical Fiber with SpectroVis Plus to measure light emissions of LEDs, fluorescent bulbs, or incandescent lights.
Motion Detector - 2
The Motion Detector is used to measure position, velocity, and acceleration of moving objects.
Salinity Sensor - 1
The Salinity Sensor precisely measures the total dissolved salt content of ocean or brackish water.
Blood Pressure Sensor - 6
The Blood Pressure Sensor is a non-invasive sensor designed to measure human blood pressure. It measures systolic, diastolic and mean arterial pressure utilizing the oscillometric technique. Pulse rate is also reported.
Conductivity Probe - 5
The Conductivity Probe determines the ionic content of an aqueous solution by measuring its conductivity. This has many applications in chemistry, biology, and environmental science.
Temperature Probe - 14
The Stainless Steel Temperature Probe is a rugged, general-purpose temperature sensor that can be used in organic liquids, salt solutions, acids, and bases. Use it as you would use a thermometer for experiments in chemistry, physics, biology, Earth science, and environmental science.
Surface Temperature Sensor - 13
The Surface Temperature Sensor is designed for use in situations in which low thermal mass or flexibility is required, or for a skin temperature measurement.
PAR Sensor - 2
The PAR (Photosynthetically Active Radiation) Sensor measures photosynthetic light levels in both air and water.
Magnetic Field Sensor - 4
The Magnetic Field Sensor can be used to study the field around permanent magnets, coils, and electrical devices. It features a rotating sensor tip to measure both transverse and longitudinal magnetic fields.
Go Link - 27
The Go!Link USB sensor interface is a quick and affordable way to get started with data-collection technology. It’s a single-channel interface that connects most Vernier sensors to your Windows or Macintosh computer’s USB port.
Hand Dynamometer - 4
Our strain-gauge based isometric Hand Dynamometer can be used to measure grip strength, pinch strength, and to perform muscle fatigue studies. Use the hand dynamometer with other sensors (e.g., EKG Sensor) to study muscular health and activity.
Electrode Support - 8
The Vernier Electrode Support connects to all standard ring-stand posts to keep sensors firmly in place during an experiment.
Colorimeter - 4
The Colorimeter is great for Beer’s law experiments, determining the concentration of unknown solutions, or studying changes in concentration vs. time.
Ammonia Ion-Selective Electrode - 1
The Ammonium Ion-Selective Electrode (ISE) can be used to measure the concentration of Ammonium (NH4+) in aqueous samples.
Biochamber 250 - 24
The BioChamber 250 is a 250 mL Nalgene bottle that can be used with a CO2 Gas Sensor and an O2 Gas Sensor to monitor gaseous carbon dioxide and oxygen levels simultaneously in a closed system. The BioChamber is useful in experiments such as photosynthesis and cell respiration.
With the bottle on its side, place the CO2 Gas Sensor into the neck of the BioChamber and the O2 Gas Sensor into the rubber grommet as shown. This design keeps the O2 Gas Sensor in the desired upright position while placing the CO2 Gas Sensor in an ideal position for gas level monitoring.
A size 6 rubber stopper fits into the rubber grommet if an O2 Gas Sensor is not used. Note: While the stopper fits snugly in the grommet, it is not guaranteed to be a watertight seal.
Biochamber 2000 (2 Liter) - 8
The BioChamber 2000 is a 2000 mL plastic chamber that can be used with a CO2 Gas Sensor and an O2 Gas Sensor to monitor gaseous carbon dioxide and oxygen levels simultaneously in a closed system. The BioChamber 2000 is particularly useful when monitoring respiration and photosynthesis. The large top opening provides easy access to insert, adjust, or remove the sample.
The BioChamber 2000 has two sensor ports. If you choose not to use both ports, a size 6 rubber stopper fits snugly in the grommet. Note: While the stopper fits well, it is not guaranteed to be a watertight seal.
LabPro is a versatile sensor interface for calculator and computer data collection.
