LabQuest Mini brings the power of Vernier’s award-winning LabQuest technology to teachers who don’t need the versatility of a standalone device. The perfect solution for educators collecting data with a Windows or Macintosh computer,...

The Pressure Sensor 400 will measure absolute pressures from 0 to 400 kPa. The sensor also operates with excellent accuracy over a wide temperature range. The robust metal fittings allow for a tight, leakproof seal to your reaction...

The Colorimeter is great for Beer’s law experiments, determining the concentration of unknown solutions, or studying changes in concentration vs. time. This 4-wavelength Colorimeter measures the amount of light transmitted through a...

The Ethanol Sensor can be used to measure the concentration of ethanol in air above an aqueous sample. This sensor can be used in a wide range of tests and experiments. It can be used to determine the rate of ethanol production during...

Use the Gas Pressure Sensor to monitor pressure changes of a gas in chemistry and biology experiments. The Gas Pressure Sensor can be used to monitor pressure changes in a gas. The range is wide enough to perform Boyle’s law yet it is...

Use the Ammonium ISE to measure levels of ammonium ions introduced from fertilizers. It can also indicate aqueous ammonia levels if sample solutions are acidified to convert NH 3 to NH 4 + . The Ammonium ISE has a combination-style,...

The Conductivity Probe determines the ionic content of an aqueous solution by measuring its conductivity. The Conductivity Probe has three ranges, providing optimal precision in any given range. Biology teachers can use this probe to...

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. The O2 Gas Sensor measures oxygen...

Our general-purpose pH Sensor can be used across disciplines, including chemistry, biology, middle school science, and environmental science. Use the pH Sensor just as you would a traditional pH meter with the additional advantages of...

Use the Tris-Compatible Flat pH Sensor to measure the pH of a solution or semisolid, such as food or soil. The Tris-Compatible Flat pH Sensor is a highly versatile sensor. Because the glass membrane is flat instead of a bulb, it is more...

The Oxidation-Reduction Potential (ORP) Sensor measures the ability of a solution to act as an oxidizing or reducing agent. Use the ORP Sensor to measure the oxidizing ability of chlorine in swimming pools or to determine when the...

The Salinity Sensor precisely measures the total dissolved salt content of ocean or brackish water. The Salinity Sensor easily and precisely measures the total dissolved salt content in an aqueous solution. Measure water with a wide...
