School Savers - Vernier GDX-PAR Go Direct Par

Vernier GDX-PAR Go Direct Par

The Go Direct PAR 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 radiation in the spectral range that is used by plants for photosynthesis. It features a waterproof sensor head and can be used to measure PPFD from sunlight and electric light sources. This sensor is ideal for experiments investigating photosynthesis and primary productivity and can be used in many agricultural and environmental science applications.

Rechargeable Battery—Ready When You Are
The robust rechargeable battery offers long battery life and provides always-ready operation when using the sensor wirelessly. Monitor battery life directly from our award-winning Vernier Graphical Analysis® app, as well as LabQuest® 3. Should the battery run low, simply connect the sensor to the charging cable and keep on collecting—no interruptions or inconvenience to you or your students.

Wireless or Wired—The Flexibility to Choose
Our Go Direct sensors connect directly to your mobile device, Chromebook™, or computer using our Vernier Graphical Analysis® app—no additional equipment or software purchases are necessary. Go Direct sensors can be used wired via USB or wirelessly via Bluetooth® wireless technology, allowing you to choose the best solution for your classroom or laboratory.

Use this sensor in a variety of experiments:
Conduct endothermic and exothermic reactions.
Investigate the freezing and melting of water.
Measure the energy content of foods.
Examine the absorption of radiant energy.
Monitor environmental conditions.
