This light and robust gas detector is the development of the proven Microtector II G450. The key features are retained - smart, interchangeable sensor technology, low cost of ownership - but extra functionality is now added.

The Microtector II G460 measures up to 7 gases simultaneously in ambient air for increased workplace safety. The sensor slots can be equipped individually. Different detection principles are available for optimal measuring results.

Measurable gases
The most common sensors detect  O2, H2S, CO, CO2 and combustible gases. Additional sensors are available for NH3, HCl, PH3, HCN, NO, NO2, SO2 and a variety of other gases.

CO2 - reliable infrared measurement
For increasing the user's safety, the Microtector II G460 detects carbon dioxide by means of a selective infrared sensor (NDIR). This sensor provides long-term stable detection values. Unlike electrochemical sensors, IR technology is not subject to cross sensitivity from toxic hydrogen sulphide.

The Microtector II G460 is the smallest detector world-wide which can be equipped with both an infrared sensor and a PID.

Monitoring for toxic volatile organic compounds (VOC)
Photoionization detector (PID) equipped instruments are increasingly viewed as the best choice for measurement of VOCs at exposure limit concentrations.  Familiar substances containing VOCs include solvents, paint thinner and nail polish remover, as well as the vapors associated with fuels such as gasoline, diesel, heating oil, kerosene and jet fuel. The category also includes many specific toxic substances such as benzene, butadiene, hexane, toluene, xylene, and many others.  Most VOC vapors are flammable at surprisingly low concentrations.  For most VOCs, however, the toxic exposure limit is exceeded long before readings reach a concentration high enough to trigger a combustible range alarm. 

Additional functions of the Microtector II G460

• IR-Sensor (CO2) for long-term stable detection values
• Poison resistant CO2 sensor
• PID for monitoring toxic volatile organic compounds (VOC)
• Smart senso technology for adaption and easy replacement

Various options allow individual adaptation to personal requirements. A number of accesssories make the Microtector II G460 a complete, useful instrument in everyday work with combustible and toxic gases.

Single-gas detector with data-logger
The Micro IV single-gas detector is the successor to the proven Micro III. The key features of the Micro III are retained - smart, interchangeable sensor technology, low cost of ownership where 1 x AA battery lasts for up to 6 months in continuous use - but extra functionality is now added.

The Micro IV contains an integrated data-logger which records and time-stamps all events. This stored data can be transmitted to a PC via either the DI220 data interface station or DS220 docking station. Three alarm levels are available (most competing instruments only offer two) in addition to STEL and TWA alarms.
The Micro IV has a very loud (95dB) sounder and high-visibility red LED alarms. Vibration alarm is also available as an option. A large display ensures that gas concentrations can be quickly and easily read by the user.

Gases available:
O2, H2S, CO, NO, NH3, HCN, HCl, SO2, H2, C2H4O, SiH4, PH3, THT, HF, COCl2, NO2, Cl2, O3, ClO2

Additional functionality of the MICRO IV

The pump and tube is quick and easy to attach, and has its' own power supply which means the run time of the Micro IV instrument is not compromised. The separate AA battery pack gives 8 hours of continuous pump operation.

Fastest monitoring of flammable gases

Superior technology
Wherever flammable gases or vapours are found, the CC28 provides the best solution for safe monitoring. ATEX-certified design, built-in EX-certified horn and bright LED lights allow safe operation within highly flammable areas. The gas alarm is transmitted to the central control panel, simultaneously warning the control room and the worker in the danger area.

Fastest detection available
Using GfG's unique sensor technology, coupled with a special "chimney-effect" the CC28 transmitter has the shortest response time in the market, detecting flammable gases using catalytic bead technology.When used in conjunction with our GMA controller series, a programmed delta alarm can shorten the response time still further. This gives an extra level of safety when handling explosive gas risks.

Smart sensor technology
Installation and sensor exchange are quick and easy using pre-calibrated smart, plug-in sensors. One-man calibration/ adjustment is possible directly at the transmitter, without opening the housing.
