Gas Monitor

Gasmonitor Plus is Crowcon’s flexible 19" rack-based control system. This microprocessor-controlled unit is used throughout the world, both onshore and offshore. Gasmonitor Plus can monitor up to 16 gas detectors or 32 fire zones per rack. Racks can be supplied separately, or built into wall mounting or floor standing enclosures.

A separate gas level display is provided for each gas detector. Gasmonitor Plus can be engineered into very large systems and tailored to suit individual site requirements. 

Simple to use
  • All day-to-day functions are available from the front panel - push buttons for simple operation
  • Unique bar-graph display per channel - provides instant representation of gas concentrations
  • Common alarm LEDs on the display card - the whole rack status can be checked at a glance.
Flexible architecture
  • System is limitlessly expandable
  • Modular construction - ultimate customisation and minimal wiring
  • Industry-standard analogue outputs - will integrate fully with existing rack-mounted protection systems on-site
  • Optional relay modules - flexible and cuts down on configuration and monitoring cabling
Easy maintenance
  • Each channel is inhibited separately - plant safety is not compromised during checks
  • Routine calibration from front panel - reduces service overheads by half
  • One universal gas card - reduces spares holding

  • Gasmaster
Ask For Price

Crowcon's NEW and ENHANCED Gasmaster Control Panel has a modular design meaning users only need purchase the required number of input modules. It can easily be extended by adding more modules at a later date.


The Crowcon Gasmaster is a compact, versatile and powerful gas detection control panel that combines simple operation with an extensive array of input and output functions.

Crowcon Gasmaster provides all the information you need about your gas and fire detectors at a glance. The large multi-lingual display shows gas levels from all detectors simultaneously and enables system adjustment and testing using buttons on the front panel. Crowcon Gasmaster can operate ‘stand-alone’ or interface with any alarm devices and control systems using a selection of outputs.

Large Display:
  • All gas levels are displayed simultaneously - enables full systems status check at a glance
  • Alarm messages can be customised to indicate the name or location of any detector in alarm
  • The LCD can be set to display in many languages
  • Menu system is intuitive and easy to use - enables configuration changes to be made easily
  • All functions, from day-to-day operation to re-calibration, can be carried out from the front panel - routine testing can be performed rapidly
  • Event log feature - enables system fault and alarm history to be viewed
Versatile input and output Features:
  • Provides analogue, relay and Modbus outputs - facilitating communication around the site
  • Flexibility - Gasmaster can monitor up to four detectors in virtually any combination of gas detectors, fire zones or Environmental Sampling Unit*. Software enables re-configuration and event log upload in an instant**
  • Two levels of independent alarm per channel - can be configured to suit site requirements
  • Remote inhibit and re-set facilities - enables control from any point on your site
  • Compatible with a 4-20mA or mV pellistor-type gas detector - mV pellistor detectors reduce system purchase and maintenance costs

  • Gasflag
Ask For Price

Gasflag is a control system for monitoring any 4-20mA flammable, toxic or oxygen gas detector. Gasflag is ideally suited to light industrial or commercial applications such as LPG monitoring on garage forecourts, chlorine detection in swimming pool dosing rooms, or methane detection in boiler rooms.

Gasflag features a loud sounder, bright LED indicators and relays for switching external devices such as audible visual alarms or valves.

  • Loud internal audible alarm
  • Clear system integrity indication
  • Accepts industry standard 4-20mA inputs
  • Multiple units can be daisy-chained
  • Variable alarm configurations
  • Integral alarm outputs
  • Simple installation
  • Minimum maintenance
  • One button operation


  • 4-20mA flammable
  • Toxic or oxygen gas detector.

  • Vortex
Ask For Price

Vortex is our most flexible control package that can be customised to meet your site requirements, however complex, without the need for extensive cabling.


Vortex is available in four formats:
Wall mounted (Vortex)
19" rack mounted (Vortex rack)
Panel mounted (Vortex panel) or
Exd Flameproof (Vortex FP)

Vortex Rack Panel comprise just the essential input, output and controller modules mounted on a DIN rail. An optional display module is available in panel-mounting and 19" Rack formats. This configuration is ideal for incorporation into a variety of specialist enclosures, such as 19" format or those with high ingress protection. Other standard features include RS-485 Modbus communications for remote non-intrusive calibration and configuration.

Channels and display
  • 1 to 12 channels (including 3 for fire) - up to 12 devices can be monitored by reviewing just one control panel, saving time and manpower
  • Each channel has 1 fault level and 3 alarm levels which can be combined in any pattern to trigger up to 32 output relays - flexibility built in, initially configured to suit your operational needs, then channels/alarms are easily customised by you if requirements change
  • Can be factory set to your requirements. Then when in situ, can easily be configured to suit your needs using Vortex PC software
  • Push buttons on front display - day-to-day operations are easily undertaken
  • LED display panel lights - faults are easily seen and whole system can be checked at a glance
Installation and maintenance
  • Modbus compatability - no extensive cabling required; cable connections within the unit are easy
  • Space within units for access to cable terminals
  • Uses industry standard communication links - simple to integrate into existing control systems
  • Any adjustments are performed electronically - minimal maintenance and no drift from adjustable potentiometers
  • Separate zones can be individually inhibited - you can work on specific areas without affecting the rest of the system
  • Modular construction - replacement parts if required, which plug straight in
Compliance and reliability
  • Validated to IEC 61508 (SIL 1) - demonstrates system dependability
  • System monitors relays continuously - coil faults are identified immediately without input from you
  • Internal battery pack* - power outs are not a problem. Internal battery pack continuously monitored for change levels and connection. System is operational at all times
