Introducing the HKM-460051 Fixed Ozone Sensor Module ZE25-03, a reliable solution designed for toxic gas detection, specifically focusing on ozone levels ranging from 0 to 10 PPM. This advanced sensor module is ideal for applications requiring precise monitoring in various environments.

The ZE25-03 model excels in detecting ozone, and it operates effectively with a dynamic range of 0 to 10 PPM, offering a resolution of 0.01 PPM. Its response time is impressive, allowing users to receive readings within 90 seconds, ensuring prompt detection of potentially hazardous gas levels. Additionally, the recovery time mirrors the response time, allowing for quick adaptability to changing gas concentrations.

This sensor module features UART output at a 3V level, facilitating easy integration into your existing systems. It operates within a voltage range of 3.7V to 5.5V and is designed with protective measures against reverse voltage connections, enhancing its durability. The operating conditions are flexible, as it can withstand temperatures from -10°C to 55°C and humidity levels from 15% to 90% RH (non-condensing), making it suitable for diverse applications.

With a warm-up time of just three minutes, the ZE25-03 is ready to perform shortly after activation. It boasts a service life of approximately two years when used in air, providing long-term value.

Included in the package is one sensor module, making it an efficient choice for those looking to incorporate reliable ozone detection into their systems. The HKM-460051 Fixed Ozone Sensor Module ZE25-03 stands out as a robust and essential tool for effective toxic gas monitoring.

Perfect, it fits like a glove.
Color: 1-Navy Blue
I really liked the sleeve, the navy blue color looks very elegant and the material feels resistant but soft to the touch. What I like the most is that the back is translucent, so you still see the design of the tablet. It works great for watching videos because it stands firm when folding it, and turning off the screen alone when closing it is very practical. Because of the price it has, the quality is excellent.

Great Protective Case for My Mother’s iPad
Color: 2-Watermelon Red, Color: 2-Watermelon Red
I bought this case along with my mother’s new iPad, and it was the perfect choice. The watermelon red color looks beautiful with the pink iPad and gives it a very clean and stylish look. The case feels sturdy without adding too much weight, which makes it comfortable for her to carry around and use every day. The stand feature works really well for watching videos, reading, and video calls. I also like that the case supports the auto wake and sleep function, which makes the iPad feel even more convenient and easy to use. The cutouts fit perfectly, and Touch ID still works without any issues. The translucent back is a nice touch because it still lets the iPad color show through while keeping it protected from scratches and bumps. Overall, this case exceeded expectations and makes a great addition for anyone wanting both protection and style for their iPad.

Good product. What you see is what you get.
Color: 1-Navy Blue
Material feels sturdy and was a perfect fit compatible for my iPad. There's adequate grip and padding for a comfortable yet slim feel. Magnets hold it close and in one position when propping it up for watching landscape videos. Back is translucent as advertised. Solid product, put it on as i opened my new ipad for immediate protection. Perfectly safe blind buy if you're also getting that 'frequently bought together' suggestion from Amazon.
