Review: Well made and does the job. - Appears to be well made and solid. It is simple to use with clear instructions. My prior PAR meter, which I paid $172 for was cheaply made and would not hold a charge. This model uses batteries which eliminates the cheap battery issue. So far I am very pleased with it.
Review: Measures PAR. - A PAR meter is useful to know if plants are receiving enough light of the kind that they need. Using this has been very useful for adjusting grow lights and understanding when a grow light is needed. I am completely reliant on the claims of accuracy since I don't own an apogee meter to test it against. Maybe someone does and can report the results. But I'm happy with it and do recommend it if you aren't sure that your plants are getting enough light, or you are not getting the results you want with the lights you have. Use the PAR reading along with DLI (daily light integral) to adjust your light intensity or distance to your plants and how many hours the light must run for the plants you are growing. Different plants need different total amounts of usable light. There are websites and videos that cover PAR and DLI which are a good resource. Addendum: This is really intended for use with indoor or greenhouse lighting, not for outdoor use. It works fine outdoors, but outdoor light is very strong and there is seldom any need to measure that. This is very useful when growing or starting plants indoors, even in a greenhouse. Plants need a certain total amount of light each day. The PAR meter measures the INTENSITY of the light spectrum that is usable by plants. Intensity is one part of the equation. The other part is QUANTITY needed which is measured by DLI (daily light interval). That varies depending on the type of plant and even its stage of growth, if you want optimal results. Think of your plants needing a certain quantity of daily light. PAR indicates how fast the light is coming in, DLI shows the total amount of light needed. PAR x Hours of light = Quantity (DLI). Knowing the PAR allows you to calculate the number of hours that grow lights must be on to get the necessary DLI. I start plants early in the year in my starter greenhouse. The days are short so I must supplement the natural light with grow lights. Usually a PAR of 700 - 750 is sufficient for most plants over about 16 hours. During the day, natural light supplies a good portion, so I use a timer to turn the grow lights on early in the morning when it is dark, then off once the sun is strong enough, then back on in the afternoon as the sun dims, and then off for the day late at night. If you are growing indoors, then the lights would be on from early morning to late at night. A PAR meter is crucial to properly adjust your lighting. A PAR meter will quickly show the insufficiency of light coming in through a window for most plants.

## Features

- ✅RELIABLE TESTER: The measurement range is between 0 and 5000 μmol/m²/sec. The cut-on wavelength is 400 nm and the cut-off wavelength is 700 nm with a tolerance of ±10 nm, which indicates that the meter is designed to measure the PAR within this defined waveband, providing accurate and reliable readings of the amount of light energy available for photosynthesis.
- ✅RECORD FUNCTION: It has the capability to store up to 100 measured values. This allows the user to easily track and review previous readings, providing a record of the changes in PAR over time. Additionally, it has a real-time display feature that shows the last four recorded data, providing a quick and convenient way for the user to view recent measurements. This feature is particularly useful for monitoring and tracking changes in light energy levels in real-time, allowing for prompt and informed decisions to be made
- ✅USAGE: A PAR meter is a valuable tool for growers, scientists, and researchers, providing accurate and reliable measurements of the amount of light energy available for photosynthesis, allowing for improved plant growth, increased energy efficiency, better crop management, and increased understanding of plant needs.
- ✅TRIPOD SOCKET: It comes with a tripod socket to provide a convenient and practical way to securely attach the meter to a tripod (not included in the set), ensuring stability and accuracy during measurements, and providing greater flexibility in taking measurements
- ✅ON THE GO TESTER: Portable, easy-to-use, flexible, and convenient tool for measuring PAR levels. It is a compact and lightweight design making it easy to carry the meter from one location to another, allowing for measurements to be taken in different parts of a greenhouse, growth chamber, or field. Ergonomic and user-friendly interface.

### ⭐⭐⭐⭐⭐ A must have.
*by B***N on December 26, 2025*

The best purchase I’ve made so far. There’s no more measuring LUX and doing conversions. I’ve been able to dial in my grow light and my plants are loving it. A must have tool for anyone who’s serious about cultivation. Great value for the asking price.
