Brief introduction: ES30 4 in 1 portable gas detection alarming device used in portable rapid detection of a variety of gas concentration, temperature and humidity measure and excessive alarm Settings. ES30 composite joining together of four gas concentration detector using a 2.31 -inch high-definition color screen real-time display, choosing the famous brand of gas sensors, main detection principles: electrochemical, infrared, catalytic combustion, thermal conductivity, PID light ion. Advanced circuit design, mature kernel algorithm processing, took a number of software patents and appearance. ES30 can detect pipeline or restricted space, concentration of the gases in the atmosphere, gas leakage or various background for a high concentration of nitrogen or oxygen single gas purity, detection of gas species more than 500 types. Features: Low water splash, anti-dust, explosion-proof, shock-proof, the circuit design,anti-static , resistance to electromagnetic interference. the protection level of IP65, with water vapor, dust filter, prevent damaged by water vapor and dust sensors and instruments. Built-in pump suction measurement, response quickly and the sampling distance is more than 10 meters, the special of gas circuit , can direct detection,negative or positive pressure - 0.5 ~ 2 kg gas, not influence the result of the measurement. the concentration of 2.31 inch high-definition color screen display in real time, alarm, time, temperature, humidity, storage, communications, electricity,charging status information,menu interface using high-resolution simulation icon displays the function of each menu name. Large capacity data storage function, with the standard 100000 data storage capacity, larger capacity can be customized. Supports real-time storage, storage timing, or only alarm concentration data and time, support the machine to view, delete data,also can through the USB interface upload data to the computer, using a machine software to analyze data and storage and print. USB charging interface, can use a computer or charging machine, compatible with cell phone charger, overcharge, discharge, over voltage,short circuit and overheating protection, level 5 precise power display, supporting USB hotplug, detector can work normally when charging, equipped with RS485 communication. Using 4500 ma high-capacity rechargeable polymer battery, can work continuously for a long time. sound and light alarm, vibration alarm, visual alarm, under-voltage alarm, fault alarm and alarm when multiple stereo display alarm status. alarm value can be set up, and optional alarm way low alarm, high alarm, interval alarm, weighted average alarm. high precision temperature and humidity measurement (optional), to compensate the temperature sensor at the same time, instrument temperature range - 40 ~ 70 degrees can detect a 400 - degree gas, higher temperature of the gas detection can be customized (optional cooling high temperature sampling filter handle or high temperature and high humidity pretreatment system). Low can detect 1 ~ 4 kinds of gas at the same time, most units free switch, conventional gas do not need to input the molecular weight, special gas need to input the molecular weight. Automatic calculation and switch, the option of the unit: PPM, mg/m3, Vol % %, LEL, PPHM, PPB, mg/L there are three displays mode can switch, at the same time display four kinds of gas concentration, big word systemic, real time curve, single channel of gas concentration in each channel manually or automatically cycle between cycle can be switch, whether can be set up according to the maximum, minimum, the name of the gas, to view history curve. Interface can choose in both English and Chinese, the default Chinese interface, simple operation hints in Chinese or English. Data recovery function, can be selectively restore or full recovery, wrong operation cause of trouble can avoid. Automatic zero tracking, long-term use is not affected by zero drift. target level calibration, which can ensure linearity and precision of measurement, and meet the national standards and local standards bureau of standard measurement at the same time. concentration calibration automatic recognition and prevent wrong operation, to avoid trouble caused by human factors. To real-time detection or timing of measured gas (for the relatively small amount), when not in detection can turn off the pump to extend time. recording and calibration log, fault countermeasures, sensor life due to remind, the next concentration calibration time remind function. Technical parameters: Gas detection: composite gas (methane CH4, O2 CO, oxygen, carbon monoxide, hydrogen sulfide H2S),optional: can detect any four kinds of gas concentration and temperature and humidity Detection range: CH4 (0 ~ 100% LEL), CO (0 ~ 500 parts per million (PPM), (0 ~ 25% VOL) of O2, H2S (0-100 parts per million (PPM), other range can be customized Distinguishability: CH4 (1% LEL), CO (1 PPM), 0.1% (VOL) of O2, H2S (0.1 PPM), higher distinguishability can be customized Test principle: electrochemical , according to the range, the environment and user needs Electrochemical principle of sensor life: more than 2 years Test method: built-in pump suction, flow 500 ml/min The type of Display: 2.31 -inch 320 x240 high-definition color screen display, five keystrokes. Accuracy: ±3% or less (F.S) Linear degrees: plus or minus 2% or less Heavy after sex: plus or minus 2% or less Alarm way: sound and light alarm, vibration alarm, visual alarm + + visual vibration of sound and light alarm, closed alarm is optional Response time: T90 20 seconds or less Recovery time: 30 seconds or less Working power supply: DC3.6 V Battery capacity: 3.6 VDC, 4500 ma high-capacity rechargeable polymer battery, take charge, discharge, overvoltage and overheating and short circuit protection function the environment of using : temperature 40 ℃ ~ + 70 ℃; Relative humidity 0-99% RH or less (built-in filters can be used in high humidity or high dust environment) Sample temperature: - 40 ℃ ~ + 70 ℃, equipped with cooling high temperature sampling filter handle, 400 degrees or higher temperature of flue gas concentration can be detected 40 ℃ ~ + 120 ℃ temperature measurement: - (optional) precision of 0.5 ℃ Humidity measurement: 0-100% RH (optional) precision 3% RH Data storage: 100000 standard data capacity, support the unit view, delete, or export data, PC communication software for free defaults to closed storage function, can be set to open, the storage time interval any Settings Communication interface: USB (charging and communication), equipped with RS485 and RS232 communication interface Interface language: English or Chinese optional Explosion-proof type: intrinsically safe Explosion-proof marks: Exia CT6 II Protection grade: IP65,anti-dust , waterproof splash Installation dimensions: 160 * 70 * 28 mm (L * W * H) Weight: 300 g Standard accessories: manual, certification, warranty CARDS, USB charger (cable), high-grade aluminum alloy instrument box, alligator clip,CD (PC communication software), humidity, dust filter each have one Optional accessories: temperature and humidity measurement function, 1.2 m telescopic handle sampling (1-10 meters hose, the standard length of 1 meter),Cooling high temperature sampling filter handle, high temperature and high humidity pretreatment system, humidity, dust filter, hang on the rope Applications: petroleum, chemical, pharmaceutical, environmental protection, flue gas analysis, air pollution and so on all need to detect gas concentration
