V-830型多種氣體檢測報(bào)警裝置是一種功能強(qiáng)大的盤裝式系統(tǒng)，由“V”系列指示計(jì)、報(bào)警部以及各種氣體檢測探頭組合而成。該設(shè)備能夠檢測可燃性氣體、毒性氣體、半導(dǎo)體特氣以及氧氣等多種氣體。其設(shè)計(jì)靈活，適合石油化工裝置的多點(diǎn)監(jiān)測。

V-830系列具有多種檢測原理可供選擇，包括接觸燃燒式、熱線型、半導(dǎo)體式、定電位電解式、薄膜型、NH3專用半導(dǎo)體式、隔膜Galvanic電池式以及混載檢測原理（兩種以上檢測原理的組合）。這種多樣化的檢測原理使得V-830能夠滿足不同環(huán)境下的氣體檢測需求。

設(shè)備采用液晶條形圖水平顯示氣體濃度，報(bào)警設(shè)定值可在檢測范圍內(nèi)任意設(shè)定。報(bào)警精度高，漏氣報(bào)警精度在±25%以內(nèi)，欠氧報(bào)警精度可達(dá)±1%以內(nèi)。報(bào)警方式直觀，指示計(jì)部和報(bào)警部均配備報(bào)警燈和蜂鳴器，漏氣時(shí)報(bào)警燈閃爍，蜂鳴器斷續(xù)響。

V-830支持交流（AC220V）和直流（DC24V）供電，使用溫度范圍為-10℃至+40℃。其設(shè)計(jì)注重用戶便利性，用戶自備表盤可降低系統(tǒng)成本，且安裝靈活簡便。此外，設(shè)備還具備外部輸出功能，支持4～20mA標(biāo)準(zhǔn)信號(hào)、0～10mV或1～5V可選信號(hào)以及RS-232輸出。

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.
