1~4 Channel Crowcon Gasmaster - Gas detection controller

Crowcon Gasmaster is a gas detection monitoring controller at the control center. Monitor fixed-type toxic gas detectors, connected to Crowcon’s new toxic gas, flammable gas and oxygen probes. With powerful features, the module design helps users just need to equip the required number of input modules, in accordance with the requirements of measuring the characteristic gas. Gasmaster central toxic gas monitoring equipment can be easily expanded by the addition of multiple modules of sensors, gas detectors suitable.

Overview

Crowcon’s Gasmaster Central Gas detection controller is a central device that controls the connection, monitoring, detection and display of powerful, compact, flexible toxic gas concentrations, including simple operation combined with a wide range of output input functions.

Crowcon Gasmaster Gas detection center controller provides all the information you need about gas and flammable gas probes with just a glimpse. The large screen with multiple lines shows the concentration of toxic gases being monitored from all connected toxic gas probes, while allowing the system to adjust and test the use of the keys on the front of the controller. Crowcon Gasmaster central gas monitoring controllers can act as a standalone system or communicate with any warning device and control system using a choice of outputs.

Large screen

All concentrations of toxic gases are displayed simultaneously on the controller’s screen – allowing the state of the entire system to be checked with just a glimpse.
Warning messages can be adjusted to show the name or location of any probe that is in a warning state.
Lcd monitors can be set to display in multiple languages.

User-friendly use

The system list of gas probes, status messages, system icons is intuitive and easily configurable to allow changes to become simple.
All routine functions as well as calibration operations, calibration due alerts, which can be performed from the front of the controller, regular inspections can be carried out quickly.
Event storage features – allow the system to record a history of errors and alerts so that it can be reviewed.

Flexible input/output features

The device also offers analogue, relay and Modbus outputs – which can be easily connected around the work area.
Flexible – The Gasmaster Central Gas monitoring controller can connect for simultaneous monitoring of up to 4 actual probes at the complex of any type of toxic gas sensor, including toxic gas probes, fire probes, or environmental testing equipment. The software of the central gas monitoring controller allows to reconfigu and even update up instantly.
Two alert levels are independent of each channel – which can be reconfigured to suit the requirements of each region.
Forbidden control and easy reconfigu reconfiguator – allows control from any one point at work.
Suitable for probes with outputs of 4~20mA or mV, reduced system cost and maintenance.

Modular Design

You just need to buy the required number of output modules with 1,2,3 or 4 channels and the system can expand later by adding to the modules.
