ND-DP3 Aerosol Photometer Calibration Device Introduction: At present, there are two calibration methods for photometers, namely the gravimetric method and the comparative method. The photometer calibration equipment developed by our company meets the requirements of both calibration methods. Our company's ND-DP3 calibration bench is a device developed for the calibration of photometers. It can simulate efficient leak detection actions in purification workshops and control efficient upstream concentration and downstream leak rate. And there is a fixed flow rate sampling and aerosol collection filter membrane device used to weigh the aerosol oil content (ug) per unit sampling volume. The ND-DP3 internal dust generating device adopts the Laskin nozzle spray type suspended particle generator (cold state), which can generate sub micron oil mist suspended particles with various diameters. ND-DP3 has simple operation and superior performance. The upstream concentration can be adjusted from 1 μ g/L to 200 μ g/L, and it is stable for a period of time. Downstream leakage rate can simulate 95%~99.995% Features: 1. A more user-friendly interface&# 8217& Flash; The host adopts a 4.5 inch LCD touch screen for display and operation, making the operation simple and clear. 2. Easy to replace and efficient&flash& Flash; Built in high-efficiency filter, capable of filtering dust particles above 0.25um, with a filtration efficiency of 99.99%. Efficient use of liquid tank seal, easy disassembly and easy replacement. (High efficiency filters are consumables and are replaced regularly based on the frequency of equipment use) 3. Built-in fog device&ndash& Flash; The equipment is equipped with a built-in aerosol generator, which uses Laskin nozzle spray type suspended particle generation (cold state) to generate submicron oil mist suspended particles with various diameters. There are two built-in aerosol generators that can store two different raw liquids. By selecting an external pressure valve, the aerosol type can be switched. 4. Imported sampling air pump&flash& Flash; The equipment adopts a German Thomas original imported sampling pump, with a sampling flow rate of 28.3L/min. This air pump has advantages such as strong stability and long service life. Technical parameters: Size: 710MM * 780MM * 1440MM Weight: 90kg Equipment shell: mainly made of iron baking paint and organic glass Power supply: 220VAC 50/60HZ Maximum power: 300W Misting volume: upstream concentration of 1ug/l to 120ug/l, downstream concentration of 0ug/l to 0.05ug/l LCD screen: 4.5 inches, touch screen Aerosol stock solution: Two types of source oils can be added simultaneously. Switch the source oil mist type by the steering valve. Efficient: Adopting a liquid tank sealed high-efficiency filter, convenient for customers to replace on their own. The filtration efficiency of high-efficiency filters is 99.99% Sampling flow rate: The sampling flow rate using the gram weight method is 1CFM (28.3L/min) Usage environment: Temperature: 10 ℃ to 45 ℃, humidity below 50%
