is a by-product of the fermentation process, and because the gas is heavier than air it can spill out of fermenting tanks and sink to the brewery floor, is also used in the packaging and bottling process and needs to be carefully monitored. To protect brewery
workers Crowcon (UK) has therefore produced a series of hand-held and wall-mounted gas detectors. All are extremely easy to use, even with a gloved hand, and have simple, single button operation. Hand-held products include the Tetra and Tetra:3 multi-gas detectors and Gasman single-gas detector. Fixed products include hazardous area-certified Xgard and Xgard IR multi-gas detectors and the Cellarsafe CO2
/O2 detector. The multi-gas hand-held range can detect up to four of the most commonly found hazardous gases in breweries, including CO2 , SO2 , H2 S and O2 gas detector or in combination with oxygen and other toxic gases. . Crowcon
has also expanded its IR (infra-red) sensor capability, introducing a new range of IR Tetra, Tetra:3 and Gasman portable detectors. IR technology offers superior reliability, measurement accuracy and stability, either as a single CO2o
When the portable units detect a gas hazard they produce a loud audible alarm (up to 95 dBA), emit a bright red/blue flashing light and vibrate. The visual and vibration signals are especially useful in zones with high levels of background noise where an audible alarm on its own may not be enough. All the units are extremely tough and hardwearing. The portable detectors can be dropped or immersed in water (or beer) and still work perfectly. The Tetra is even designed to float, so can be easily retrieved if dropped in a vat, barrel or other container of liquid. All Crowcon products are ingress protected to at least IP65 and, in the case of the Xgard fixed range, are IEC Ex, UL and ATEX approved for use in hazardous areas.

GasAlertMicro 5 IR Multi-Gas Detector
New from BW Technol ogies (UK) by Honeywell, the GasAlertMicro 5 IR portable gas detector monitors up to five atmospheric hazards including carbon dioxide (CO2). Using a non-dispersive infrared (NDIR) sensor, the ultra-compact GasAlertMicro 5 IR is a compet itively priced option for monitoring potentially deadly CO2 levels.
The GasAlertMicro 5 IR offers unsurpassed ease-of-use. With a variety of user-settable field options, the GasAlertMicro 5 IR can be customized to suit a variety of needs in different industries. Passcode protection prevents unauthor-ized users from modifying settings, ensuring tamper-proof operation. Options including user-downloadable datalogging and flexible power supplies combined with a lightweight design make the GasAlertMicro 5 IR the premier multi-gas detector on the market.

New Advanced Portable Formaldehyde Monitor
The Formaldemeter htV, from Enmet Corporation (USA), is a direct-reading portable formaldehyde monitor. The model htV incorporates humidity compensation for improved performance at low con- centrations and when taking formalde-hyde read ings in different environ ments. Temperature and relative humidity can also be displayed. The htV offers many desirable features including fast response, readings on a 4-digit LCD in under 10 seconds, compact size, rugged construction and very simple operation with no special training required. Formaldehyde concentrations can be displayed in either ppm or mg/m3
. Field
calibration can be accomplished with the supplied, simple to use gas standard. The Formaldemeter htV kit is complete with instrument, instruction manual, calibration standard and carrying case. Data logging accessories are also available.
