QC-4 (S) explosion-proof air sampler epidemic

QC-4 (S) explosion-proof air sampler Product Description: ◇ Flow: 0.1 ~ 1.5L / min 0.1 ~ 3L / min ◇ electronic timing, AC and DC First, the technical indicators: 1 flow range 0.1 ~ 1.5L / min 2, rated flow 2.5L / min (4500Pa load) 3 2.5 4 meter accuracy, flow stability ≤5% 5, the timing range 0-99min 6, error ≤1% 7, power supply 9.6V / 1.8Ah Ni- H 8, the type of protection intrinsically safe iaIICT4 9, dimensions 120 × 60 × 190 mm3 10, Weight: 1.3Kg Second, an overview: QC-4 (S) explosion-proof air sampler is for use in explosive atmospheres collect gas samples The conventional instruments. It consists of pump, flow meter, when the control circuit and power supply. Pump for the pump, with the suction pressure, load capacity, flow stability, low noise. The instrument is compact, small size, light weight, easy to carry, easy to operate, durable, stable performance, can be widely used to monitor sector and metallurgy, mining, chemicals, building materials and other fields of health and epidemic prevention, environmental monitoring. Third, the structural characteristics: 1, the working principle: 2, explosion protection: intrinsically safe power supply 9.6V / 1.8Ah battery pack, silicone rubber potting motor. Three reverse parallel diode and motor constitute protective element Note: In an explosive atmosphere is prohibited removable and rechargeable 3 instrument, instrument names and functions of the various components shown in Figure: The use of methods: 1, sample preparation before: turn on the power Press the "sampling" button, check the battery, the battery voltage status using multi-level LED light-emitting diode display, from right to left in descending order, the green area represents the voltage is normal, yellow zone indicates that the instrument should be charged, the red area indicates that the battery too owe pressure, should immediately stop charging, otherwise it will shorten battery life. Turn off the power when charging, plug in the charger, then market power, green light indicates the charger, about 15 hours, the green light goes out, charging stops automatically. Note Do not charge in explosive atmospheres. 2, field sampling: After selecting the sampling points, the sampling device is mounted on a tripod, adjusted to the proper height, install good absorption bottles, bottle brackets and security to keep the meter sampling perpendicular to the ground, and maintaining the flow stable. Turn the power switch sampling, the time is displayed as "30" min, set the sampling time needed adjustment were "+1" and "-1" key, time range is 0 ~ 99min. Time setting and then press the "sampling" button, the instrument start working, adjust the flow to the required sampling flow automatically stops time after time display to zero. If you press the "reset" button, the time to reply to the last set time, but also to re-adjust the sampling time, start the second sample. During sampling, if you want to abort sampling, press the "reset" button.
