V-830型多种气体检测报警装置是一种功能强大的盘装式系统，由“V”系列指示计、报警部以及各种气体检测探头组合而成。该设备能够检测可燃性气体、毒性气体、半导体特气以及氧气等多种气体。其设计灵活，适合石油化工装置的多点监测。

V-830系列具有多种检测原理可供选择，包括接触燃烧式、热线型、半导体式、定电位电解式、薄膜型、NH3专用半导体式、隔膜Galvanic电池式以及混载检测原理（两种以上检测原理的组合）。这种多样化的检测原理使得V-830能够满足不同环境下的气体检测需求。

设备采用液晶条形图水平显示气体浓度，报警设定值可在检测范围内任意设定。报警精度高，漏气报警精度在±25%以内，欠氧报警精度可达±1%以内。报警方式直观，指示计部和报警部均配备报警灯和蜂鸣器，漏气时报警灯闪烁，蜂鸣器断续响。

V-830支持交流（AC220V）和直流（DC24V）供电，使用温度范围为-10℃至+40℃。其设计注重用户便利性，用户自备表盘可降低系统成本，且安装灵活简便。此外，设备还具备外部输出功能，支持4～20mA标准信号、0～10mV或1～5V可选信号以及RS-232输出。

The V-830 is a versatile gas detection and alarm system designed for monitoring combustible gases, toxic gases, semiconductor specialty gases, and oxygen. It is a panel-mounted system composed of the “V” series indicators, alarm units, and various gas detection probes. This system is particularly suitable for multi-point monitoring in petrochemical installations.

The V-830 series offers a range of detection principles, including catalytic combustion, thermal conductivity, semiconductor, electrochemical, thin-film, NH3-specific semiconductor, galvanic battery, and hybrid detection (combination of two or more detection principles). This diversity allows the V-830 to meet the gas detection requirements of various environments.

Gas concentration is displayed using a horizontal LCD bar graph, and alarm set points can be freely adjusted within the detection range. The alarm accuracy is high, with leak detection accuracy within ±25% and oxygen deficiency detection accuracy within ±1%. The alarm indication is intuitive, with flashing alarm lights and intermittent beeping for leak detection.

The V-830 supports both AC (220V) and DC (24V) power supply and operates within a temperature range of -10℃ to +40℃. The system is designed with user convenience in mind, allowing users to supply their own panels to reduce system costs and offering flexible installation options. Additionally, the V-830 features external output capabilities, supporting standard 4-20mA signals, optional 0-10mV or 1-5V signals, and RS-232 output.
