ZHK6140 Dustfall and Rainfall Sampler

● The independently developed intelligent rain and snow sensor can automatically determine the precipitation situation and determine the working status of the instrument, without being disturbed by any external objects. It has the detection characteristics of rain (snow) intensity greater than 0.01 mm/h or raindrops with a diameter of 0.5 mm.

● The collection funnel and rain gauge have automatic heating function, which can melt and collect snowfall in a timely manner.

● Cabinet heating and dehumidification function, maintaining a temperature of over 10 ℃ inside the cabinet in winter to avoid pipeline icing.

● Cabinet ventilation function, the temperature inside the cabinet will not be too high, and the working environment temperature of the refrigerator is suitable.

● The independently patented electric push rod switchcover mechanism is equipped with a mechanical limitposition sensor to avoid damage to the equipmentcaused by excessive transmission. The unique anticold and ice resistant switch cover is abnormal. Thedust cover is opened within 60 seconds after the startof precipitation and closed within 5 minutes after thestop of precipitation, and the time can be set.

● High brightness seven inch capacitive touch displayscreen, with a simple and intuitive operation interface,and simple and fast parameter settings.

● Equipped with a micro Bluetooth printing module and a USB data export module, rainfall sampling data can be exported with just one click.

● The function of automatically saving measurement data in case of power failure, which can be automatically recognized after power restoration without the need for personnel operation.

● Integrated with self checking, leakage and lightning protection functions, it has strong anti-interference ability and high reliability.

● The entire mechanism adopts outdoor spraying technology, suitable for long-term exposure to wind, rain, and sun, with a long service life. The sampling funnel is treated with Teflon spray passivation to eliminate the impact of heavy metals on water quality, with an inner diameter of 300 mm.

● Equipped with dry settling sampling function, using standard dust reduction cylinder with an inner diameter of 150mm and a height of 300mm.

● 71 L constant temperature refrigerator is used to store samples, and a self-designed temperature control system effectively adjusts the refrigeration temperature of the samples.

● External standard tipping bucket rain and snowgauge with a resolution of 0.1 mm and built-in snowmelting function.

● Multiple sampling modes, flexible sampling based onwhole time period, rainfall, frequency, time, and othermodes; Segmented sampling can be divided into 8sections, with samples collected for 8 days.
