With the cutting-edge Fuel Cell HCHO sensor, the DT-900A offers unparalleled accuracy and reliability. Its easy-to-read LCD display with backlight allows you to clearly see the concentration levels of Formaldehyde (HCHO) and Total Volatile Organic Compounds (TVOC) in the air in real time. Not only does it give precise measurements, but it also calculates the value of the Air Pollution Index (API) to help you better understand your indoor air quality.

The DT-900A goes beyond just monitoring – it alerts you when pollution levels exceed safe limits. The built-in Sound and Light alarm system ensures you’re immediately informed of any changes in air quality. With its auto power-off feature, you can save energy while maintaining a safe and healthy environment.

The CEM DT-904 Digital RCD Tester is a state-of-the-art device designed to meet the needs of modern electrical testing. One of its standout features is the ability to deliver a 2000ms readout, making it highly effective for testing the latest delay action breakers which require precise timing measurements.

Accuracy is paramount when it comes to RCD testing, and the DT-904 excels in this area with its digital readout of tipping time. This feature provides exact timing measurements that are crucial for assessing the safety and efficiency of electrical installations. Additionally, the tester includes two neon lamps that serve as a quick visual reference for correct wiring, adding an extra layer of verification to the testing process.

One of the most convenient features of the DT-904 is that it operates directly from the mains supply, eliminating the need for batteries. This not only makes the tester more environmentally friendly but also reduces the weight and complexity of the device, making it more manageable in a variety of testing environments.

The compact and lightweight design of the CEM DT-904 makes it easy to handle and operate. Its simplicity does not compromise its functionality, making it an ideal choice for both novice and experienced professionals. The inclusion of a zero-cross circuitry is particularly noteworthy, as it allows testing at both the 0° and 180° points of the sine wave.

This capability enables the tester to display both the minimum (best) and maximum (worst) trip times, providing comprehensive data about the electrical safety of the system being tested.

Furthermore, the DT-904 features a data hold function that freezes the digital trip time displayed on the screen. This function is crucial for ensuring accurate readings, as it eliminates the possibility of human error during the readout process.

With all these features packed into a single device, the CEM DT-904 Digital RCD Tester stands out as a highly effective tool for ensuring electrical safety and compliance in various installations.
