GfG Instrumentation - Model G222E -Dual-gas monitor
If you need to monitor 1 or 2 specific gases, the G222E is the best choice. It can be equipped with either one or two electrochemical sensors, allowing you to reliably detect a variety of toxic gases, oxygen or hydrogen in different measuring ranges. The G222E is approved for use in Ex zone. Its very durable, handy and lightweight design offers the best possible combination of safety and comfort to the people carrying it. The measured values, types of gas, measuring range and charging status of the battery can be read on the display at any point. A single alkaline battery will power the device for up to three months of continuous operating time. If a dangerous gas concentration is detected, the G222E will warn you using a visual, acoustic and vibration alarm.
Sometimes you already know, which specific gas will pose a potential risk. If you need to monitor carbon monoxide, ammonia, hydrogen sulfide or hydrogen specifically, a one gas detector is an adequate and cost-effective solution. Our G222E from the Micro 5 family of products offers an additional slot for a second electrochemical sensor to monitor the oxygen concentration in addition to a toxic gas or H2. You can also combine sensors for different toxic gases or use to sensors for the same gas but in different measuring ranges, depending on what is required in your application.
Handy, durable and reliable
When designing the Micro 5 series, we prioritized safety and wearing comfort. Since it is approved for hazardous ATEX environment as well as mining, there are no limits to the areas of application it can be used in. The housing is made of rubberized plastic and is protected against the ingress of dust and water (IP54; soon IP68). With its small size and low weight of a maximum of 4 ounces, anyone wearing it can easily forget it’s there at all, even when working in confined spaces – unless, of course, it is alerting them to dangerous gas concentrations. No alarm will go unnoticed, even in loud environments or areas with low visibility, as the loud buzzer (103 db(A)), highly visible alarm LEDs and vibrations to signal them.
For 1 or 2 toxic gases, H2 or O2
The G222E is equipped with one or two EC sensors, depending on your requirements. This way, one or two toxic gases, hydrogen or oxygen can be selectively monitored. A list of all measured gases and their corresponding measuring ranges can be found at the bottom of this page. The sensors are durable and reliable. For the daily bump test, a calibration cap is attached to the detector to insert the test gas. The internal data logger can be read out using the smart calibration cap, a PC connected through a USB cable and the Config software. A docking station DS400 or DS404 is used to calibrate and adjust the G222E.
Durable and suitable for everyday use
The LC display shows the measured gas concentrations as well as the type of gas and unit. The status of the battery is also visible at any point. The display can be rotated by 180 degrees at the press of a button, to facilitate reading the displayed information when the device is fastened to work clothes using the crocodile clip. The G222 is powered by a single battery, providing enough energy for nine months use (at 10-hour work days) or 90 days continuous operation time. It can be replaced quickly, ensuring that the gas detector is ready to use again in less than a minute.
