Gas Detection 17
New 10.0 eV Lamp for
Photoionisation Sensor Line
New Sensor and Transmitter for Hydrocarbons and Organic Solvents
The EX-5155, 24 VDC, Sensor/Transmitter features a solid-state MOS sensor, which can be calibrated for ppm level detection of a wide range of hydrocarbon gases and organic solvents including; acetone, xylene, MEK, and methyl alcohol.
The MOS sensor can also be used for detecting certain common toxic gases, including, for example; NH3, CO and H2S. The EX-5155 is approved for Class I, Division 1, Groups B, C and D. It features a liquid crystal display, 4-20 mA output and non-intrusive calibration. The EX-5155 operates on 24 VDC power provided by a PLC or any one of several controllers available from ENMET Corporation (USA).

Industrial Scientific Announces Product Recall of GasBadge Plus Single-Gas Monitors
Baseline-MOCON (USA) a subsidiary of MOCON (NASDAQ: MOCO), is announcing a new 10.0 eV lamp energy level for its piD- TECH® plus photoionisation sensor line. The new lamp will now give users increased specificity when determining the presence of volatile organic compounds (VOC) such as benzene, toluene, ethylbenzene and xylene (BTEX).
For first time, this energy level has been incorporated into a small photoionisation sensor. This means that original equipment manufacturers of lightweight, portable testing units which accept a 4P cell dimensional profile can now offer their users new performance capability.
The new lamp provides improved BTEX compound analysis over previously available energies. It offers increased specificity over the 10.6 eV and increased sensitivity over the 9.6 eV options.
The linear dynamic ranges for the Baseline- MOCON’s piD-TECH® plus sensors which incorporate the new 10.0 eV lamp are (ppb=parts per billion; ppm=parts per million):
Sensor type Normal range MDQ Isobutylene Isobutylene Black Label 10.0 6,000 ppm 150 ppb Bronze 10.0 600 ppm 50 ppb Silver 10.0 60 ppm 15 ppb
The new generation sensors are ideal for instrumentation manufacturers who want to add state-of-the art, low-level VOC detection to their portable or stationary monitors. The piD-TECH® plus line sets a new standard by being able to measure concentrations lower than previously possible with other comparably-sized sensors.
By offering three lamp energy levels, the piD-TECH® plus now offers users a choice of selectivity and discrimination. Improvements in the detector cell production process also results in more robust cell performance characteristics. When these capabilities are coupled with broad dynamic range and insensitivity to humidity, the piD-TECH® plus becomes the most versatile PID sensor available.
Baseline-MOCON has engineered extremely low electrical entity parameters (voltage, current, capacitance, etc.) into the piD- TECH® plus series which enable operation in hazardous environments. As a result, the entire line has passed Underwriter’s Laboratories “certified component” requirements. This reduces the steps manufacturers have to take to obtain an “intrinsically-safe” certification rating for instruments using piD-TECH® plus sensors. Further, Baseline-MOCON is ISO 9001:2000 certified.

Industrial Scientific Corporation has determined that the GasBadge® Plus single-gas instrument may not properly indicate a low battery condition resulting in a failure to alarm or instrument shut down. As a result, for safety reasons, Industrial Scientific is issuing a recall of all current GasBadge Plus instruments (v2.2 and earlier; manufactured prior to February 2012).

Geotech Launches New Portable Landfill Gas Analyser
The new Geotech GA5000 portable landfill gas analyser arrives in Jan 2012 with a colour-screen and a 3-year warranty. Up-to-the-minute as a new-generation analyser, the GA5000 has mobile phone-style intuitive menus, tactile buttons and it is fast, small and light. With a clear, full-colour, daylight-readable screen in several language choices, the GA5000 is about 25 percent smaller and lighter than the GA2000 which it supersedes. Advances include greater accuracy to ± 0.5 percent.
The GA5000 measures up to six gases without external pods. The three standard gases are methane (CH4), carbon dioxide (CO2) and oxygen (O2). Additional gas options include hydrogen-compensated carbon monoxide (CO) and hydrogen sulphide (H2S) at low- or high-ranges to 10,000ppm. The GA5000 holds 2,000 sample point IDs, 4,000 readings and 2,000 events. Analysis response time is halved to just 10 seconds, saving operator time. User-driven improvements on the GA5000 include all inlet ports now at the top of the analyser with functionality which choices include the option of internal flow measurement.
At the press of a button, anyone can see context-sensitive operational and user calibration assistance. These technical help screens explain what to do next. The mobile phone-style keypad and screen make data entry easy. The GA5000 meets UK and international certification standards including ISO 17025, ATEX and IECEx.
Operational costs are reduced and fewer replacement filters needed. User calibration is really easy with menu-driven, easy-to-follow on-screen instructions and the event log, now standard, records calibration data automatically.
The GA5000 has evolved from earlier models and uses the latest tried and tested technology for in-field biogas analysis. Its development is based on 22-years’ experience by Geotech in design, manufacture and service of portable landfill gas analysers – and on vitally important feedback from customers and users. That specialist experience combines to deliver dependable reliability and the latest in user-requested operational functionality.
