gb90 liquefied gas leak detector [Manager Tian 15106992328 0531-88790109] liquefied gas leak detector liquefied gas leakage detector LPG leakage alarm introduced portable liquefied the GB90 liquefied petroleum gas detector GasBadgeEX (GB90) detector, using high-performance catalytic combustion gas sensor can be used in petrochemical, environmental accidents, liquefied petroleum gas, liquefied petroleum gas, coal gas and other industries to monitor a variety of combustible gas, including: alkanes, liquefied petroleum gas, liquefied petroleum gas, liquefied petroleum gas, etc., and its display unit is % LEL-minimum lower explosive limit, resolution up to 1% LEL. Novel instrument is compact and easy to carry. Parameter settings and zero calibration process can be set to the password-protected to prevent error setup and operation of non-qualified personnel. The GB90 liquefied gas detector with sound and light and vibration alarm function, according to the specific needs of users at the same time, the alarm can be set with a silencer and latch functions. Instrument internal memory can be up to 30 days of testing data record (record to see for one minute), user via infrared interface of the instrument brought to the internal data uploaded to a PC or monitor instrument, easy to query and analyze. 【Features】: the high imitation Chen waterproof, protection class up to IP67 units of measurement can be switched (LEL /% VOL) ??95 dB Treble alarm, ultra-bright alarm lights and vibration alarm continuously records the last 15 alarm, can be downloaded via infrared interface Data lithium-ion rechargeable battery, at least 15 hours of continuous operation Technical parameters】: shell: polycarbonate shell, waterproof anti-corrosion, anti-electromagnetic radiation volume: 94 mm x 50 mm x 25 mm Weight: 140 g sensors: high-performance catalytic combustion type sensor detection gas: combustible gas measurement range: 0-100% LEL Resolution: 1% LEL display: LCD icon display, easy to operate, gas data direct reading, with the backlight alarm: the user preset high and low alarm, sound and light vibration alarm battery -15 hours data records: lithium battery: continuous recording, records the last 15 alarm time and duration, peak record, download data or direct printing via infrared interface.
