Gas Warning Station Gasmaster with Sensors of X/TXGard-Series
Stationary gas warning station (with ATEX- permission) for adaption of gas sensors for O2, O3, O2, O3, CO, CO2, NH3, H2S

The gasmaster is a gas warning station/ gas warning control centre with a large display. This gas warning station is purchasable in a 1- and a 4- channel version as well as with a PC-interface. Even the gasmaster is equipped with two alarm relays, due to which e.g. signal lamps/ -horns or ventilators can be operated. The adaptable ATEX- approved gas sensors are available here as well: for flammable gasses (EX), oxygen and toxic gasses (TOX). The gas sensors are divided according to the gas, the functionality (e.g. with analogue-, relay- output…) or the display type. Thus there are sensors with an integrated display (as a local display) or without a display. There are gas sensors for nearly every gas to select: methane, propane, butane, pentane, LPG, ethanol, ethylene, hydrogen, acetylene, benzenes (unleaded), phosphine, oxygen, ozone, chlorine, carbon monoxide, carbon dioxide, hydrogen sulphide, sulphur dioxide, ammoniac, … (more gasses on request please). Systems of gas warning stations and gas warning sensors will be always delivered completely configured, calibrated and tested before delivery. A general survey of gas meters for operator protection (mostly portable) you will find here. If you have further questions concerning the gas warning station, take a look at the following technical data or call our hotline: UK customers +44(0) 23 809 870 30 / US customers +1-410-387-7703. Our technicians and engineers will be pleased to inform you concerning the gas warning station or any other product in terms of regulation and control or scales and balances of PCE Instruments

Further gas warning stations/ gas sensors for CO2 you will find here.

The reaction time of the IR gas warning station is about T90 <30 sec. and the zero drift round about ±2 % per month. So that the measuring data can be determined with high accuracy and for purposes of outer protection of the gas warning station, some optional purchasableSun Protection for Gas Warning Station protectors are eligible. Depending on the  installation location the additional sun protector  is reasonable. If the Capsulet deflector against water yet -Gas Warning Station sensors operate outdoors or in rooms or halls that are often being cleaned with water or that are occasionally being fumigated, the extra capsuled deflector against water yet is recommendable. For very humid roomAdapter- Xgard-Typ 1- Gas Warning Station- better Methan Measurements conditions and offshore application as well as installation on ships, a combination between gas warning station and Collector Taper -Gas Warning Station weather-proof protection cap is recommendable. For the site identification of light gasses (e.g. methane) the collector taper is used preferably, that works like a cap and alleviates the gas supply for the gas sensor. Please review the matching solution with our technicians or use our contact form.

Advantage over conventional gas sensors: 
A large advantage the IR- gas sensor holds is its product life (>5 years) and its low long-term drift, which lowers the annual calibration charges to zero. Furthermore sensors of this type are equipped with complete temperature compensation. The ATEX, UL and IECEx certification allows an application worldwide.

Technical Data for Gas Warning Station Gasmaster (for 1-4 Gas Sensors)

Digital display and control unit for gas sensors shown above. The gas warning station gasmaster is deliverable in two models. GM-1 for an Input sensor and GM-4 for up to 4 gas sensors (simultaneous display of all 4 measuring datas). Those two types are besides the standard analogue output even purchasable with an additional RS-232-data interface. Furthermore the device is equipped with relay outputs e.g. for activation of an all-round warning light. The enclosure is dust- and waterjet- proof. The gas warning station is further equipped with a standard backup-battery in order to operate even during power outage.
