Low concentration constant temperature and humidity weighing system

Description :

　　1： Overview and Structure of RC-1220 Low Concentration Constant Temperature and Humidity Weighing System:

　　1. The new constant temperature and humidity weighing system places a high-precision balance in the high-precision constant temperature and humidity system. The sample to be weighed is placed in the system, equilibrated for 24 hours, and then manually weighed. This system overcomes the impact of temperature and humidity changes in the laboratory environment on weighing results and improves the accuracy of weighing.

　　2. The box body is made of cold-rolled steel plate surface with electrostatic spray coating, which is hard and firm, and has extremely strong anti rust ability. The front door is fully glass and can be opened, with two reserved operation workstations.

　　3. The box is equipped with pulleys and self-locking function, which facilitates the movement and fixation of the whole machine, and the balance works normally in the weighing environment. At the same time, the sample is balanced in a high-precision constant temperature and humidity environment to ensure the weighing accuracy of the sample. The system has automatic mechanical fault alarm function and automatic water tank water shortage alarm function. It is designed reasonably and adopts multi-level seismic measures to ensure the continuous and stable operation of the balance.

　　4. The anti vibration adjustment system developed for many years ensures that the vibration caused by the compressor during operation will not affect the zeroing of the 100000 scale.

　　5. Latex long arm gloves with glove boxes are used, allowing operators to carry out weighing work more tactilely.

　　The wind speed inside the constant temperature and humidity weighing system does not affect the storage, retrieval, etc. of the samples. The constant temperature and humidity system adopts a cycle of upward air supply and downward air suction to ensure uniform temperature and humidity inside the box. The box door is equipped with a full frame transparent window for observing changes in the indoor samples. The observation window is made of organic panels, which have the advantages of transparency, heat insulation, and are not prone to steam frosting; And silicone gloves should be equipped to ensure that the temperature and humidity fluctuations inside the constant temperature and humidity chamber meet the requirements of HJ836-2 017 "Determination of Low Concentration Particulate Matter in Fixed Pollution Source Waste Gas by Weight Method" during manual operation, and the balance weighing is not affected. This product meets the requirements of GB2423.1-2001 Test A "Low Temperature Test Method":

　　GB2423.2-2001 Test B "High Temperature Test Method";

　　GB2423.3-93 Test Ca "Constant Damp Heat Test Method" GBT1740-2007

　　Meet the standards HJ618-2011, HJ656-2013, and HJ836-2017 of the Ministry of Environmental Protection for the determination of low concentration particulate matter in fixed source exhaust gas by weight method; According to the regulations, constant temperature and humidity adjustment ensure the accuracy of the sample weighing results and the stability of the sample weighing data

　　The upper part of the box is the experimental area, the bottom is a frame type, and the electrical control cabinet is located on the right side of the equipment. Reasonably designed and durable. On the premise of complying with * * * standards and ensuring stable performance in all aspects, the equipment is more practical and easy to control. Moreover, the device is easy to install, easy to operate, and basically does not require

　　Characteristics such as daily maintenance.

　　The studio uses internationally recognized SUS304 # stainless steel plates with rounded corners, smooth and easy to clean.
