Introducing a formaldehyde sensor with very low cross-sensitivity to ethanol!

The SFA30 is a digital formaldehyde sensor designed for easy integration into air purifiers, demand-controlled ventilation systems, and more. It has very low cross-sensitivity to other VOC gases and excellent detection performance for formaldehyde. Additionally, a digital UART and I2C interface can be optionally selected, and standard electrical connectors along with various mounting options make product implementation easy. 【Specifications (partial)】 ■ Measurement range: 0 - 1000 ppb ■ Accuracy: ±20 ppb or ±20% m.v. ■ Sensor output: Formaldehyde concentration in ppb, RH, T ■ Cross-sensitivity to ethanol: < 0.5% ■ Detection limit: < 20 ppb ■ Lifespan: > 6 years *For more details, please download the PDF or feel free to contact us.

On November 6th (Thursday) to 7th (Friday), 2025, we held the "Human Body Day 2025" at the NAC Image Technology Akasaka Multi-Purpose Space. We have uploaded videos of the highlights from each company and the presentations that took place on the day to our website. We encourage you to take a look. ---[Report on Human Body Day 2025 is here]------------------- https://info.nacinc.jp/jintaiday2025-report ------------------------------------------------------------------------- On the day of the event, participants were able to experience a wide range of products in a hands-on session format, including motion capture, force plates, eye tracking, and human body analysis software. We received numerous comments from attendees expressing high satisfaction, saying, "It was great to gain various information all at once," which makes us very happy. NAC Image Technology will continue to provide "valuable products to our customers." We hope you will join us for our next event as well.

The "Mechanical Stitch Method" by Nichinichisui Road Machinery Co., Ltd. is a new technique that allows for the repair of metal cracks without the application of heat. By using special bolts and reinforcement plates, cracks are physically removed, and repairs are made without causing any thermal impact to the base material. Repairs can be carried out in environments where open flames cannot be used. Since no heat is applied, the disassembly of equipment is minimized. ◎ For more details, please contact us. ◎ If a detailed technical explanation is needed, please contact us.
