Advantages of our PAR Meter product Advantages of our PAR Meter product High reduction measurement of photosynthetic radiation. By checking PAR levels, growers can optimize lighting conditions to promote healthier crop growth and increase productivityIn indoor greenhouses, detecting PAR levels and timely improving LED grow lights for light supplementation can increase light utilization efficiencyIn outdoor fields, connecting cables with a 12 'long track can detect farther locationsPowerful record storage, capable of storing 99 logs and tracing historical detection results Mesures Broad Spectrum Provides accurate readings with a range of 0-4,000 µmol/m²s, the cut-on wavelength is 400 nm and the cut-off wavelength is 700 nm, Easy to use, clear numerical values Use connecting cables to connect the PAR Meter Main Unit and PAR Meter Sensor Unit; Collect data immediatelyThe PAR reading is displayed on a large screen, providing clearer measurement results;You can adjust the mode to view historical recordsAt the same time, the remaining battery level will be displayed, reminding the user of the time to replace the battery Greenhouse is often used PAR meters are widely used in agricultural greenhouses. By detecting LED growt lights, farmers can quickly adjust the lighting to promote healthy crop growth and increase profits Suitable for multiple scenarios This PAR Meter is perfect for measuring indoor and outdoor light levels in farmland, ideal for crop seedlings and other light-dependent applications.
