Brief introduction: Can collect selectively to wet fallout (precipitation) samples and dry fallout samples (dust). Rely on rainfall sensor monitoring, only in the rain (snow) day, open the lid and seal dry dust barrel. After the rain (snow) stop the lid closed, lest dry fall into. Collect dry fall at the same time. Samples stored in the constant temperature box. Features: 1. Automatic judgment precipitation and decided to instrument's working state. 2. Arms four connecting rod drive mechanism on/off function: the precipitation within 60 seconds after the start of the open the lid, precipitation within five minutes after stop close the lid. 3. The sampling funnel or bucket: inner diameter 300 mm to 600 mm; Material is stainless steel material, inner wall coating teflon protective layer, elimination of the influence of heavy metal exceeds bid. 4. High brightness display screen, can be in (- 40 ~ 70) ℃ environment normal work; Safety voltage power supply, high safety. 5. Power-fail protection: in the case of a power to save the measurement data. After power supply recovery, automatic identification, without operation. 6. Set the introspection, leakage and against lightning protection functions in an organic whole, strong anti-jamming capability, high reliability. 7. Sampler shell material: stainless steel material, long service life, suitable for long outdoor environment lee blowing rain sun; At the same time has the dust sampling function. 8. The sample storage: constant temperature cooler storage samples; In (3 ~ 5 ℃ temperature setting. 9. Snow melt function: the host in the environment temperature is lower than 2 degrees detected precipitation at the same time, automatic start heating collection funnel snowfall. 10. Can realize more bottle packing samples function (separated into at least two different sample barrels), meet the needs of the routine environmental monitoring and research department of acid rain. 11. Precipitation rainfall recorder information real-time monitoring, data record keeping, can store 2000 set of precipitation, stop time and rainfall information, etc. 12. The data transmission with RS232 communication interface and the USB data interface, convenient guide data transmission, can pick up the micro printer on-site printing or meet U disk archived export. Technical indicators Rain device sensitivity: the rainfall intensity 0.01 mm/h or 0.5 mm diameter of the rain After the rain funnel flowing inside diameter: the diameter of 300 mm - 600 - mm (optional) Rainfall open delay time: 60 s or less (adjustable) The rain stopped customs cover delay time: 5 min or less (adjustable) Storage rainfall records: 2000 set of rainfall records Sample preservation: constant temperature storage, cooler temperature (3 ℃ to 5 ℃) set arbitrary; Rain gauge adopt the rain mouth diameter: diameter (200, 300, 600, optional) mm The rain gauge resolution: 0.1 mm Rain gauge rainfall measurement error: 10 mm or less rainfall, better than + / - 0.4 mm; > 10 mm rainfall, plus or minus 4% or less Rain gauge to measure the maximum rainfall intensity: 0.03 mm/min - 4 mm/min Power consumption: standby < 30 w, the biggest < 300 w Working power supply: AC220V plus or minus 10 ℅, 50 hz Working temperature: - 40 ~ 70 ℃ Signal output: RS232 or USB
