The PAR (Photosynthetically Active Radiation) Sensor reports the Photosynthetic Photon Flux Density (PPFD), which corresponds to micromoles of photons per meter squared per second (μmol m-2 s-1). This is the power of electromagnetic...

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 Pyranometer measures the power of electromagnetic radiation. It is sensitive to near infrared, visible, and UV radiation, where 90% of solar energy is concentrated. It reads in watts per square meter, so it is great for experiments...

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...

The Relative Humidity Sensor can be used for weather studies, monitoring greenhouses, or determining days when static electrical discharges could be a problem. The Relative Humidity Sensor contains an integrated circuit that can be used...

Dieser Sensor wird zum Messen von Spannungen im Bereich von -30 bis +30 V eingesetzt. Der Einsatz des Sensors wird notwendig bei allen Experimenten mit Spannungen über 10 V, z.B. beim Arbeiten mit großen Solarpanels. Da der Sensor einen...

The Differential Voltage Probe is designed for exploring the basic principles of electricity. Use this probe to measure voltages in low voltage AC and DC circuits. With a range of ±6.0 V, this system is ideal for use in “battery and...

This Voltage Probe can be used with the Vernier LabPro, LabQuest, LabQuest Mini, Go!Link, Easylink, SensorDAQ and CBL 2 to measure direct voltage. The Voltage Probe is a bipolar sensor. The black lead is grounded along with the...

The Spirometer is designed to make human respiratory measurements at rest and during moderate activity. Use it to perform a variety of experiments related to air flow and lung volume. The removable flow head (22 mm ID/30 mm OD) makes it...

The Current Probe can be used to measure currents in low-voltage AC and DC circuits or for electrochemistry experiments. The Current Probe measures DC and low-frequency AC currents up to 600 mA. Use Current Probes in combination with...
