Landtek PAR Meter for LED Grow Lights, High Precision Quantum Sensor PPFD Tester 400-700nm | 18.8cm (7.4in) Length

• HIGH PRECISION PPFD MESUREMENT — This Par Meter integrated with highly accurate Quantum Sensor Measuring for Photosynthetic Photon Flux Density (PPFD) up to 5000 μmol/m²/sec in the wavelengths range from 400 nm to 700 nm. No more guessing. Having such a PPDF meter can help you dial in your lighting needs based on growth stage as to not over expose young plants and underexpose flowering plants
• THREE MEASUREMENT MODES — This PAR Meter for Led Grow Lights offers 3 measurement modes, which can be selected by the user according to needs. There are Dynamic Measurements is for every second measurement, Hold Measurement is for rhe last dynamic measurement, and the Logged Measurement is for the data recording in meter
• DATA DAGGED FUNCTION — With a large LCD display, user can see the real-time PPFD levels and also the last 4 historical data on display. This Par meter can store up to 100 data measurements by manual saving at indexes 1 through 100 which is especially useful for monitoring and tracking changes in light energy levels in real time
• IT IS A VALUABLE TOOL FOR GROWERS / SCIENTISTIS/ RESEARCHERS — The use of a PPFD Meter will be a great help in measuring the amount of energy your plants were getting at various distances from light and also the strength of light. Helping users make quick and accurate decisions to optimize your grows
• HANDLED / TRIPOD MOUNTING — LANDTEK Light Par meter is very well made, compact, solid construction, simple operation and accurate. There's a handy 1/4” tripod socket that enables you to attach a selfie stick so that you can reach back and take measurements in far corners of your greenhouse. (Please Noted:the meter automatically shuts off after 3 minutes when no buttons are pressed)

• Power On and Select Mode — Insert 2 AAA batteries. Press the power button. Select your desired measurement mode: Dynamic for real-time readings, Hold for the last reading, or Logged for data recording.
• Position and Measure — Point the quantum sensor directly at the light source or plant canopy at the desired distance. Ensure the sensor is perpendicular to the light for accurate PPFD readings within the 400-700nm spectrum.
• Record and Analyze Data — In Logged mode, press the save button to store readings (up to 100). View current and historical data on the LCD display. Use the 1/4” tripod socket for stable positioning during extended measurements.
