1316-002 G313 Single Gas Detector for Methane (Natural Gas), Propane, Refrigerant and other MOS Detectable VOCs, with NiMH Rechargeable Battery Pack by GfG

Pinpoint the Smallest Leaks

Small leaks in pipes or storage tanks can release enough gas to build up dangerous concentrations. The careful inspection of flanged, threaded and soldered connections before and after installation will ensure equipment and worker safety. The G300 leak detector will make leakage sprays a thing of the past

Clear and simple displays and warnings

Changing gas concentrations are indicated audibly and visually. The frequency of the audible warning rises with gas concentrations, allowing the user to pinpoint leaks. The bar graph display will warn the user if dangerous gas concentrations arise.

Light, compact and durable

Designed for one-handed operation, the G300 reacts to concentrations as small as 5 ppm and measures up to more than 10,000 ppm or 1% volume. The sensor is located at the end of a flexible gooseneck or a helix cable to allow the user to reach difficult or unreachable locations. The G300 is available with or without explosion protection for ammonia and combustible gases. The G311 operates on four "AA" alkaline batteries. All others have a rechargeable battery with run times of more than eight hours.

CC22-765-DM CC 22 Series Fixed Transmitter with Ethylene (C₂H₄) Sensor, 0 - 100% LEL Range, Display / Modbus by GfG

Are you looking for an innovative and cost-effective transmitter for combustible gases, but without the need for explosion protection? Then a GfG 22 series transmitter is the right choice.

Time-proven and innovative

The CC 22 works according to the heat of reaction principle, a proven method for measuring combustible gases. The transmitters are fitted with high-performance electronics for voltage stabilization, processing of readings, and temperature compensation. Follow-up costs are minimized thanks to the long lifespan of the sensors.

Universal signal transmission

Either an analog or digital output signal can be transmitted by the CC 22 by means of a Modbus interface. Due to the different types of signal transmission, a 22 series transmitter can be connected to almost any gas detection system, also as an extra measuring point or as a replacement transmitter on existing systems.

Signal processing

The embedded software of the CC 22 linearises the measuring signal and compensates for the effects of temperature. As a result, correct readings are transmitted even with weather related fluctuations in temperature. The software allows problems to be detected, and the Modbus version also indicates any required service or maintenance work.

Weather protection

A weatherproof housing not only protects transmitters against exposure to wind and weather, but also against contamination and excessive temperatures caused by direct sunlight.

Optional colored graphic display

The clear graphic display of the CC 22 is self explanatory and allows you to read off the current status and other important information with ease. The display enables you to navigate effortlessly through the unit's concise menu and to change settings or even calibrate, depending on your user authorization. In the event of an alarm, the display will turn red.

Operation buttons

The buttons on the transmitter allow the unit to be calibrated and settings to be adjusted through the menu as needed.

The application areas of the dust and water-protected structure range from production and storage areas to disposal sites, biogas plants, mines and oil rigs.

Calibration adapter

In order to perform regular bump tests, a calibration adapter is used on the transmitter, which ensures a uniform and secure supply of gas.

Easy and convenient service

GfG offers full after-the-sale commissioning and field service support.

Features

• Uses the catalytic combustion principle
• Long service life of the sensors
• High efficiency and low follow-up costs
• Sturdy plastic housing (IP 54)
• Cost effective single-man adjustment
• Affordable solution for many measuring tasks

2811-4505-002 EC 28 Gas Transmitter with Sensor, Ammonia (NH3), 0-500 ppm, Display by GfG

Advanced Technology

Wherever hazards are expected, the EC 28 transmitter and GfG s proven monitoring systems are the right choice for reliable surveillance. The ATEX-certified design, an integrated, Ex-proof buzzer, and bright alarm LEDs provide the highest safety in hazardous areas by including visual and audible alarms. The gas alarm not only alerts the person in the control room of hazards, but also the person on-site.

Easy handling

Smart sensor technology allows a user to install the transmitter or to replace a sensor within a few seconds just plug the sensor into the transmitter. Adjustments are done directly at the transmitter using touch keys or with the remote control (one-person calibration).

Remote Control RC2

Ammonia and hydrogen are lighter than air. With the transmitter installed close to the ceiling, GfG can provide permanently connected cables with plugs for the remote control, which allow the user to do all adjustments without having to climb a ladder. In addition, one remote control can be used for several transmitters, which helps cut costs and increase efficiency.

The remote control display is always identical to that of the transmitter, making inspection, service, and calibration considerably simple.

The remote control reads the current gas concentration and can be used as an external display.

Integrated Alarm Saves Money on Ex-proof Alarm and Wiring!

The EC 28 D model shows the current gas concentration on-site at the display of the transmitter and also at GfG s GMA controller.

The EC 28 DAprovides additional bright alarm LEDs and a buzzer avoiding costs for a separate Ex-proof horn and an Ex-proof light. You also save money on wiring to connect the controller and alarm devices.

In combination with GfG's flexible control units, the EC 28 provides various possibilities for reliable and cost-effective gas monitoring.
