Closed space oxygen gas alarm, hypoxia detection alarm

Shandong Rute Security specializes in gas detection equipment for over 16 years,Closed space oxygen gas alarm, oxygen deficiency detection alarm, industrial fixed oxygen alarm mainly consists of two parts: gas detector and gas alarm controller. The probe part adopts electrochemical sensor, with a detection range of 0-25% VOL and explosion-proof mark

Exdb IICT6 Gb； Extb IIIC T80 ℃ Db, gas and dust dual explosion-proof, protection level IP66. The equipment can upload DCS, PLC, fire protection system, and computer software. When the concentration of oxygen gas is lower or higher than the predetermined alarm value, the alarm will emit an audible and visual alarm signal to remind.

Closed space oxygen gas alarm, hypoxia detection alarm

The RT series toxic/flammable gas detector is an industrial combustible, toxic and harmful gas detection instrument designed in accordance with the national standards GB15322.1-2019 and GB16808-2008. The explosion-proof design of this series of products complies with the 2021 national explosion-proof new standard, with an explosion-proof level of EXdb II CT6Gb and a protection level of up to IP66. The wiring methods include branch line, bus or wireless, and the installation method can also choose wall mounted or magnetic suction. There are also various power supply methods: host power supply, DC24V switch power supply, AC220V or battery power supply. The probe can be equipped with LCD display function and integrated sound and light alarm function to achieve on-site sound and light alarm notification at the detection point. Multiple styles to meet the testing needs of different places.

RT gas detectors use imported sensors with high accuracy and strong stability, and are widely used in fields such as petroleum, chemical, oil depots, automobiles, pharmaceuticals, steel, shipbuilding, and other places where flammable gases exist.

Product Features:

1. Using imported components, stable performance and low power consumption.

2. High precision and fast response speed.

3. M-bus/4-20mA/switch/wireless 4G.

4. Zero calibration, modification of alarm points, and self inspection can be achieved through remote control or controller without the need to open the cover.

5. On site LCD concentration display, LED on-site status (power, low alarm, high alarm, fault) indication, more intuitive.

6. On site sound and light alarm (optional), easy installation and long transmission distance.

7. The detector has a simple and elegant appearance.

8. Sensor module hot swappable design.
