STT250 specifications

The Honeywell STT250 is a versatile and robust portable gas detection device designed to monitor a wide range of hazardous gases in various environments. Known for its reliability and accuracy, the STT250 is a vital tool for industries such as oil and gas, chemical manufacturing, and emergency response. This gas detector combines advanced technology with user-friendly features, making it an ideal choice for both field personnel and safety managers.

One of the key features of the Honeywell STT250 is its multi-gas detection capability. This device is capable of detecting up to five gases simultaneously, including oxygen (O2), combustible gases (LEL), and toxic gases such as hydrogen sulfide (H2S) and carbon monoxide (CO). This multi-gas functionality ensures comprehensive monitoring of potential hazards, allowing users to respond promptly to toxic environments.

Equipped with advanced sensor technology, the STT250 provides accurate and real-time readings, ensuring that users are always informed about gas concentrations in their surroundings. The device utilizes electrochemical sensors for specific toxic gases, ensuring high sensitivity and selectivity. For combustible gas detection, the STT250 employs a catalytic bead sensor, providing reliable performance even in challenging conditions.

In terms of user experience, the Honeywell STT250 features a large, easy-to-read display that shows gas concentration levels and other critical information at a glance. With its intuitive interface, users can navigate the device with ease, making it accessible even for those with minimal training. Additionally, the device includes audible, visual, and tactile alarms to alert users when gas levels exceed predetermined thresholds, ensuring their safety.

The STT250 is designed for portability and durability. Its lightweight construction and ergonomic design allow for easy handling, while the rugged housing ensures it can withstand harsh environmental conditions, such as exposure to water, dust, and impact. This level of durability makes the STT250 suitable for both indoor and outdoor applications.

Battery life is another notable characteristic of the Honeywell STT250. The device is equipped with a long-lasting rechargeable battery that ensures extended operational time, minimizing downtime and the need for frequent recharging.

Overall, the Honeywell STT250 is a sophisticated gas detection solution that combines advanced technologies with practicality. Its multiple gas detection capability, accurate sensors, user-friendly interface, and durable design make it an essential tool for ensuring safety in hazardous work environments.
