Pulse Amplitude Modulated (PAM) technology is a widely used method for measuring chlorophyll fluorescence, offering precise insights into plant photosynthetic efficiency. The FluorPen is a handheld chlorophyll fluorescence instrument that combines PAM and OJIP rapid fluorescence kinetic measurement technologies. It stands out as the most compact, fully integrated, and cost-effective device in its class, making advanced chlorophyll fluorescence analysis accessible to researchers and field scientists alike.
With its phone-sized design, the FluorPen offers unmatched portability. It comes in multiple configurations, including fixed leaf clips, split leaf clips, probe types, and specialized models like the Monitoring FluorPen for long-term field studies and AquaPen for algae monitoring. This versatility ensures it can adapt to various applications—whether measuring leaves, fruits, soil, moss, lichens, or water-based samples.
The FluorPen is packed with features: it includes built-in photosynthetically active radiation (PAR), real-time chlorophyll fluorescence measurements, photon yield, Kautsky effect, two sets of fluorescence quenching protocols, and three light response curves. It also supports 10 pre-programmed measurement protocols, including the OJIP test. With over 60 parameters available, it captures nearly 500 fluorescence data points per second during the OJIP test and calculates 26 key parameters through its software. Optional GPS integration allows for time-stamped, geolocated data, enhancing spatial and temporal analysis.
Its user-friendly interface features dual-button operation, enabling users to select measurement programs, adjust light intensity, set intervals, and store data efficiently. The device is equipped with high-resolution sampling (up to 10 microseconds), ensuring accurate capture of fast fluorescence transients and detailed quenching curves. It also supports wireless data transmission via GPRS, USB, or Bluetooth, and runs on four AAA batteries for up to 48 hours of continuous use.
Applications of the FluorPen span across diverse research areas. For instance, Ruiz-Sanchez et al. used it alongside stomatal conductance meters to compare the photosynthetic performance of mycorrhizal and non-mycorrhizal rice under drought stress, finding that mycorrhizal plants maintained higher Fv/Fm values. Another study by Fernandez-Marin et al. explored the role of the xanthophyll cycle in desiccation tolerance using FluorPen, revealing how zeaxanthin helps protect lichens from light stress during rehydration.
Whether in the lab or the field, the FluorPen brings cutting-edge chlorophyll fluorescence technology to your fingertips, empowering researchers with powerful, portable, and precise tools for plant physiological studies.

Ceramic kamado grill (also called Kamado Barbecue Grill, Ceramic Grill, egg shaped barbecue grill) is a high-end outdoor barbecue equipment that combines high efficiency, environmental protection and beauty. This series of products uses high-quality natural ceramics as the main material. It is not only healthy, environmentally friendly, non-toxic and harmless, but also has excellent high temperature resistance. It can withstand high temperatures of more than 800°C without cracking, ensuring safety and stability during the barbecue process.
- High-quality materials: Made of natural ceramic, the surface is specially glazed to present a beautiful fish scale texture or water ripple texture, which is durable and easy to clean. At the same time, ceramics have excellent thermal insulation properties and can effectively save fuel.
- Multifunctional design: Built-in stainless steel grilling net and cast iron stove plate to ensure that food is heated evenly and tastes delicious. The product is also equipped with an adjustable height design to meet different barbecue needs. In addition, some models also have a folding function for easy carrying and storage.
- Safe and convenient: The product is equipped with a dual-display thermometer in Celsius and Fahrenheit to ensure safety during use, timely detect excessive temperature problems, and ensure food and personal safety. At the same time, the easy-to-assemble and clean design allows users to easily enjoy the fun of barbecue.
- Diverse choices: Ceramic Grill and Kamado Barbecue Grill offer a variety of sizes and colors, such as 18-inch tabletop, 21-inch medium-sized, 24-inch outdoor, etc., including black, red, green, blue, white, etc., to meet the personalized needs of different users.
- High efficiency and energy saving: The thermal insulation performance of ceramic materials reduces heat loss during barbecue, thereby saving fuel. In addition, the unique structural design also improves combustion efficiency, ensuring that food is cooked quickly and has a better flavor.

How to use this ceramic Kamado BBQ grill?
1.Open the upper cover of the oven and put charcoal into the furnace. You can put 1-2KG at a time. (The oven saves charcoal and can be used by one person according to the specific situation. Put 0.8KG of charcoal and it can be used for 3 hours)
2.Use an electronic igniter or a special igniter for the oven to ignite the charcoal (for safety, it is strictly prohibited to use gasoline. Use flammable liquid fuels such as sesame to ignite.) When it is not very hot, you can first put the grill grid and wait for the charcoal to burn fully.
3.When most of the charcoal is ignited, simply spread the charcoal evenly to allow the charcoal to burn more evenly. Then you can put food on top of the grilling net (large pieces of meat can be cooked first to make it more delicious.). Then cover the lid and adjust the temperature by shaking the top and air door, and then wait for the food to grill. During this period, you can open the lid to watch the food grill. (During the barbecue process, if you need to add charcoal, you can open half of the grill net, make an opening, and then add charcoal.)
