32 Gas Detection Multi Gas Clip Battery Lasts Months Instead of Hours


Gas Clip Technologies (USA) have developed a technologically advanced portable multi gas detector, the Multi Gas Clip (MGC). MGC is the first portable multi gas detector with a two month continuous run time without ever needing to be recharged. Shut down the instrument nightly and the battery can last up to four months. This extended battery life is due to the utilisation of low power photometric technology. Instead of draining the battery with pellistor technology, which has been around since the 1950’s, the MGC uses a low power photo diode infrared source. This conserves power during every test, so the battery lasts and lasts.


The MGC also eliminates the need to frequently calibrate. It can go six months without being calibrated saving precious time, resources and lives. While the MGC uses more sophisticated technology than other portable multi gas detectors, one button operation makes it easy to use.


Each MGC instrument is 100% quality control tested, not just a random sample of instruments, to ensure complete customer satisfaction. Servicing and maintenance are just a phone call away and there is never a fee to help keep the instruments operational at top performance to protect your most precious resource – your employees. If there is ever a need to replace an instrument, Gas Clip Technologies has a “no questions asked” return policy.


Multi Gas Clip has now made testing for the presence or absence of combustible gases, H2S, CO, or O2 more reliable, user friendly, and cost-effective. 26268pr@reply-direct.com

Diaphragm Pump in Micro Format


Gardner Denver Thomas (Germany) has once more expanded its range of gas diaphragm pumps.


The series 1010 is the smallest miniature diaphragm pump ever developed by the Thomas Division. The smallest product in the range of motor diaphragm pumps only weighs about 15 grams.


Even more impressive is the 1010’s overall performance. Reliability, extremely low power consumption and high power density in combination with miniaturised dimensions were the main focus of this development.


All these properties have been confirmed by comprehensive tests and 4,000 hours of non-stop operation. The newly developed valve unit guarantees optimum delivery, also of wet gases, and enables good controllability for


volume flow rates ranging from 100 to 800 ml/min. Hence, the majority of applications in the field of gas analysis are covered. Different diaphragm versions, optimised for vacuum duty only as well as combined pressure and vacuum use, are available.


At present, durable bell-type armature motors are used to drive the pump. These are particularly efficient and easy to control thanks to their ironless winding. They even fulfill operational requirements for Ex-certified devices. A drive for less rigid requirements is currently in preparation.


The pump head can be rotated by 180°, which facilitates flexibility when integrating the pump. Assembly of the pump head, chamber and console is realised with two brackets. These brackets create a uniform pre-load resulting in a reproducible and consistent pneumatic performance for the pump’s entire life span.


Target applications for the 1010 series are primarily portable gas detection and warning devices next to medical engineering and laboratory technology – but in particular for devices with limited mounting space.

The smartMODUL-FLOW from smartGAS Mikrosensorik GmbH (Germany) is now available for the detection of Carbon Monoxide (CO) in concentrations between 0 an 2,000 ppm. The no odour gas is toxic and can be fatal in higher concentrations; the TLV in industrial environments is 30 ppm.


CO can be formed in various processes for example during incomplete combustion of fossil fuels. Monitoring of CO in exhaust systems gives information about the process and can be used for optimisation of the combustion process. The electro-chemical sensors, which are often used in these kind of applications, have various disadvantages. Besides the ageing of these sensors, a concentration of CO above a certain limit can eventually destroy the electro-chemical sensor. The new smartMODUL CO sensor utilises infrared (NDIR) absorption and therefore doesn't have this disadvantage. The sensor is very stable and requires almost no maintenance or additional calibrations resulting in lower


operating costs. An additional optical filter can reduce the influence of CO2. The OEM sensor is available with many standard interfaces like Modbus ASCII with RS485, UART or 4…20 mA enabling an easy integration into existing control architectures. 22997pr@reply-direct.com

Bulletproof Gas Detector Now SIL 2 Certified


Detcon (USA), an IST Company, have announced that their environmentally bulletproof TP- 700 hydrogen sulphide MOS gas detector is now certified SIL 2 capable. The device recently underwent stringent functional safety assessments by third party agency exida and was found to be in compliance with IEC61508: 2010 Parts 1-7.


The Model 700’s rugged framework includes an electro- polished 316 stainless steel housing with fully encapsulated electronics and dual layer surge protection. These details in design virtually eliminate the threat of outside damage to internal components due to water ingress, corrosion, vibration and transient spikes.


Sensor elements are simple plug-in components for easy replacement in the field while operator interface is user friendly via a small handheld magnet. Configuration and routine calibration are intuitive and menu driven with fully scripted instructions. The intelligent transmitter module features dual redundant outputs; a linear 4-20 milliamp analog signal and a Modbus RS-485 serial output. Product options include a Remote Alarm Module (RAM), HART, Foundation Fieldbus, and wireless. Additional approvals include CE, ATEX, CSA, CEPEL and GOST.
