  • DR BRUCE BUGBEE: Apogee DLI PAR meters have been designed and refined by Dr. Bruce Bugbee, a world-famous crop physiologist.
  • DLI-600 Full-Spectrum ePAR-Meter: This meter measures the 400-750 nm ePAR range, known for its extended photosynthetically active properties. It provides research-grade DLI and photoperiod data, recording spot measurements, daily light integral (mol·m-2·d-1), and photoperiod in 0.2-hour increments for up to 99 days.
  • ePAR/DLI/Photoperiod: Measuring the daily light integral (DLI) and photoperiod is essential for optimizing plant health, triggering flowering, and influencing morphology. ePPFD, DLI, and photoperiod data can be viewed on-screen or downloaded via USB-C for analysis.
  • RUGGED AND VERSATILE: IP65-rated for durability in harsh environments. Can be placed on any surface or mounted with standard camera equipment. Includes protective case, soil stake, AAA batteries, USB-C cable, screwdriver, and QuickStart guide.

If I had to force a complaint I'd say I wish I didn't have to remove 2 screws to access the USB-C port, but I have no doubt it's concealed where it is for a reason, and it's not much of an inconvenience at all. Otherwise it's all positive marks for the DLI-600. The universal thread is a great idea, I picked up an inexpensive, telescoping tripod/wand to use for quick and long term readings. Compared these readings with a 2 year old MQ-510 and they're nearly identical. Easy to access the files via the included USB-C cable on my laptop. You get what you pay for and I have no doubt this DLI-600 will be taking accurate readings for years to come. No more burning, or under lighting my plants. Keep up the good work, Dr. Bruce.

Very easy to use. It is easy to give a plant too much light. If you use this meter your plants will get just what they need.

Compré tres de estos instrumentos para iniciar unos experimentos y uno de los fotometros ni siquiera se prendió. Esto atrasa considerablemente el trabajo que debia iniciar. Decepcionada. Intentare devolver el instrumento dañado ya que me encuentro en otro pais. Por el valor del producto no deberian enviar piezas con fallas

This died within a month while out in thunderstorms occasionally. It seemed accurate but to read it you have to open it, which disconnects the batteries and forgets today’s results.It only records CSV with data for every half hour for ten days (and daily for 100 days I think), even though it samples more frequently.It didn’t show up when connected to my iPad or modern Mac, but it did intermittently connect to my very old Mac (from 2006).I loved it despite these problems but for the price I need it to survive the weather.

The battery compartment screw was completely stripped and the screw falls out. It arrived like that. Incredibly poor design for an expensive instrument.
