1. INTRODUCTION
The 90E portable gas detector is a state-of-the-art gas leak detector. We employ
the best Japanese high quality semi-conductor sensor and embedded
microcontroller to detect gas leakage with high sensitivity and fast reaction time.
The detector is waterproof, dustproof, explosion-proof, and easy to use with
super high reliability. This detector is widely used in oil, coal, municipal
construction, chemical engineering, environmental protection, metallurgy,
refining, gas transmission and distribution, biochemistry, agriculture and
pharmaceutical industries.
2. FEATURES & SPECIFICATIONS
ACCURATE: Accurate Made in Japan sensor, most sensitive with ppm (0-10,000ppm)
concentration display. Comes FACTORY CALIBRATED. Turn ON and GO.
ALARMS: Adjustable Audio, visual, and vibration alarms alert when preset levels are reached.
COLOR DISPLAY: Large LCD screen. Shock proof, water proof, dust proof and explosion proof.
USES: Designed for inspectors, utility workers, refinery workers, maintenance engineers and
technicians.

**!WARNING **
lDO NOT turn on the detector when it’s off and being charged.
lDO NOT charge the detector at leak detection site. Explosions may be caused by
sparks introduced from plugging / unplugging the charger.
lDO NOT charge the detector when it is ON.
lPrevent dropping the detector and vibrations.
lDO NOT use sensor tip to touch other objects nor block sensor tip.
lThe detector will only detect gas concentration when in the main screen.
lThe detector should not be stored or used where there are caustic gases (such as
CL2), or under other rigorous circumstances (no excessive high and low
temperature, high humidity, electromagnetic field and sunlight).
lAfter long-term use, if there is dust on detector surface, please clean it lightly with
clean soft cloth, instead of caustic solvents or hard things.
