Carbon Dioxide (CO₂) Gas
Carbon dioxide (CO₂) is a colorless gas with a density about 60% higher than that of dry air. Carbon dioxide is odorless at normally encountered concentrations, however, at high concentrations, it has a sharp and acidic odor.
It is a versatile industrial material, used, for example, as an inert gas in welding and fire extinguishers, as a pressurizing gas in air guns and oil recovery, and as a supercritical fluid solvent in decaffeination of coffee and supercritical drying. It is added to drinking water and carbonated beverages including beer and sparkling wine to add effervescence. The frozen solid form of CO₂, known as dry ice is used as a refrigerant and as an abrasive in dry-ice blasting.

GDA 40127: Carbon Dioxide Gas Detection Controller
The GDA 40127 Carbon Dioxide Gas Detection Controller is a standalone gas detector unit with inbuilt display, sounder, flasher, relays and alarm driver using an non dispersive infra red sensor.
Designed, manufactured and supported locally in Australia.
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.
SENKO SI-100C: Explosion Proof Gas Sensor
SI-100C is a IEC Ex explosion proof gas sensor ready to installed hazardous and non-hazardous areas to prevent gas hazards caused oxygen depletion, toxic gas or combustible gas. Available to detect over 25 different gas types, see Ordering Information for details.
GDA 4500: Single Point Gas Sampling System
The GDA 4500 is designed to be used where sensors are placed in areas that are difficult to gain access such as pits and elevated areas.
Designed, manufactured and supported locally in Australia.
GDA 4508: Multi Point Sampling System
The GD 4508/16 is a 1 to 16 point gas sampling system for use in commercial buildings to control fresh air make up in rooms relative to external fresh air. Available for: Carbon Monoxide (CO), Oxygen (O₂) or Carbon Dioxide (CO2).
Designed, manufactured and supported locally in Australia.
