Review on 🌱 ALPTHY Digital Light Meter for Plants - Handheld Lux Meter for Ambient Temperature Measurement with 200,000 Lux Range, Color Backlight, MAX/MIN, Data Hold, and Low Battery Indication by Dwayne Pore

This meter has a nice large backlit color LCD screen. It measures the ambient temperature in degrees Celsius (good information when evaluating the efficiency of solar panels, which is what I intend to do). Illuminance measurements are available in units (lux and foot candles). A foot candle is a lumen spread over a 1 square foot area. In any case, this meter helps estimate how much light is reaching aquatic plants, which helps me set up a lighting schedule for my aquarium. In addition, it has a hold function to save the last reading and MIN/MAX functions to display the highest and lowest readings in case you need to bring the device to a light source where you cannot read the screen at the same time. . To exit MIN/MAX mode, press and hold the MIN/MAX button until the mode is exited. The sensor assembly has a nice soft plastic cover that seals well and allows the sensor to block all ambient light when not in use.
