SENKO SI-100 : Explosion Proof Gas Detector
SI-100 is a IEC Ex fixed gas detector installed in a place where potential gas hazard occurs to measure oxygen, toxic gas and combustible gas. It shows not only the concentration of gas but also diagnostic result of the unit itself through the LCD display and can be connected to the controller with a standard 4-20mA analog output communication or RS-485 digital communication.
- SI-100 measures the concentration of the flammable gas, toxic gas, oxygen and display with LCD
- Easy magnetic bar operation
- Big digital LCD installed with a blue backlight
- Explosive proof structure
- IP65: Water and dust resistant structure
- Simple push button gas calibration
- RUSSIA Gost-R Certification
- EUROPE electromagnetic waves fitness Certification
- Australian Certificate of Calibration
Locally Technically Supported by Gas Detection Australia

| Battery Rooms | The SI-100C and a range of associated Gas Detection Australia controllers can be used in battery room gas detection to detect hydrogen in battery rooms and sound alarms. The battery room gas detection systems comprise of a hydrogen gas sensor SI-100C and a gas sensor control unit. The Gas Detection Australia control unit GDA 4020 or GDA 4011 is situated external to the battery room to display the gas concentrations and the alarm status. The battery room gas detection system can then be interfaced to extraction fans, sounders or other apparatus. For smaller battery charging rooms the standalone GDA 40126 can provide an integrated sensor and controller with outputs to drive extraction fans and sounders. DESIGNED, MANUFACTURED AND SUPPORTED IN AUSTRALIA. |
| Sewage Treatment Plants | The presence of Hydrogen Sulphide can be detected by using the Gas Detection Australia GDA 2529 gas detector/ gas sensor to detect leaks of Hydrogen Sulphide and evoke deodorisation plant. The Gas Detection Australia GDA 2560 Methane gas detector / gas sensor can be used to monitor for leaks of LEL levels of methane gas .In digester applications Carbon dioxide can be detected using the GDA 4350 DESIGNED, MANUFACTURED AND SUPPORTED IN AUSTRALIA. |
