VERNIER GO DIRECT PAR SENSOR
The Vernier Go Direct PAR (Photosynthetically Active Radiation) Sensor measures photosynthetic light levels in both air and water. The 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.

GDX-PAR features a waterproof sensor head with a marine grade stainless steel connector to a 5m waterproof cable 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 Vernier Go Direct™ robust rechargeable battery offers long battery life and provides always-ready operation. Monitor battery life directly from Vernier's free Graphical Analysis™ app as well as Vernier 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.

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

Vernier Graphical Analysis™ Pro includes all the features of the free Vernier Graphical Analysis app, plus enhanced functions for more advanced analysis. Its illustrative experiment videos and interactive graphing capabilities inspire students to explore crucial scientific concepts and analyze data in new complex and insightful ways.
Vernier Graphical Analysis™ Pro is compatible with most Vernier sensors and multiple operating systems and devices.
