Back gas gas detector mkrq901n
The MKRQ901N series flawed gas detector is a fire electronics product for detecting natural gas (main component methane) and liquefied petroleum gas (main component propane, butane) concentration exceeding the standard. The MKRQ901 series flawed gas detector is a fire electronics product for detecting natural gas (main component methane) and liquefied petroleum gas (main component propane, butane) concentration. When the gas occurs
- That is, plug and play, no converter is required, installation is extremely simple and convenient
- The test instrument has the function of preventing mold, insect -proof, and anti -corrosion.
The MKRQ901 series flawed gas detector is a fire electronics product for detecting natural gas (main component methane) and liquefied petroleum gas (main component propane, butane) concentration. When the gas is leaked, the gas concentration value reaches the alarm value (5%Lel) of the gas detector. The red flash of the gas detection instrument continued to flash, and the 80 ~ 110DB voice alarm was issued. At the same time, the linkage (robotic hand/solenoid valve/exhaust device) can achieve the purpose of cutting the gas source until the surrounding gas concentration is lower than the alarm setting value. Network gas detector (ZigBee function: mkrq901z; NB-IoT function: MKRQ901N; WIFI function: MKRQ 901W; Bluetooth function: mkrq 901L), realized voice calls and remotely push alarm information on the basis of non-network detectors. That is to plug and use it without a converter. The installation is extremely simple and convenient. The detector has the function of preventing mold, insect -proof, and corrosion. Flame retardant ABS plastic is easy to clean. It can effectively prevent and reduce the explosive accident caused by the leakage of combustible gas (natural gas, liquefied petroleum and gas). It is widely used in restaurants, kitchens, hospitals, hotels, oil plants, garages, gas stations, etc.

Commodity pricing
Commodity price = number of order interval 1*range specification unit price 1+order range number 2*range specification unit price 2.
Example: The call rate is 0.3 yuan/minute for a part of no more than 3 minutes, and the part of more than 3 minutes is pressed at 0.2 yuan/minute; if the user calls for 8 minutes, the fee is charged at 3*0.3+5*0.2 = 1.9 yuan.
Commodity price = order of order*number of sections.
Example: The call rate is 0.3 yuan/minute for no more than 3 minutes, and if it exceeds 3 minutes, it is 0.2 yuan/minute; if the user calls for 2 minutes, the fee is charged at 2*0.3 = 0.6 yuan; if the user calls for 8 minutes, it will be collected. The cost is 8*0.2 = 1.6 yuan.
Commodity price = order quantity*unit price.
