Portable Multi Gas Detector KT-602 （one-to-four type） Accurate acousto-optic alarm, large screen display, simple operation, with intelligent sensor. All these advantages centre on a small but solid gas detector KT-602 which is applied to multi gas detection. As the most sensitive multi gas alarm detector in the present industrial circle, KT-602 responds quickly and accurately to the toxic gas, in order to alarm in time if the leakage or danger occurred. Hostile operating environment is a stern challenge for the detector, such as broiling, severe cold, damp, dusty, etc. KT-602 was designed for exceedingly rugged surroundings, with explosion-proof and flame retardant crust, light and portable. Inspection and alarm will be continuous even if the detector were dropped or crashed. It is the primary inspection tool with high performance-price ratio and multiple functions in the field of multiple gas detecting. Features
Aseismatic design is applied to rugged surroundings; Continuously gas concentration and composition LCD real-time display; Rechargeable lithium battery (continuous working period can be 16~18 hours); 95 dB acoustic alarm and two wide-angle optic alarm; Built-in vibration alarm which is applied for noisy environment; Two stage alarm threshold: the low alarm point and high alarm is applicable to all gas; Simple automatic calibration program and plug-in replaceable electrochemical sensor; Fully functional self-testing: sensor, integrity of battery and circuit, acoustic & visual & vibration three-stage alarm. Small figure and light weight Common application includes mining, metallurgy, petroleum, chemical, power, telecommunication, urban construction, etc. Functions
Real-time detection for the concentration of appointed gas. Gas Alert Micro series have a wide application, including HAZMAT response, enclosure space entry and post fire inspection. The deadline date and alarm threshold can be adjusted based on the request in special industry. Password protection capability: only the authorized user can modify the preset parameter.
