BX-7200 electronic orifice flow calibrator
1、 Product Overview:
The BX-7200 model adopts microcontroller and sensor technology, designed and manufactured according to the requirements of the National Environmental Protection Administration's "Technical Requirements and Testing Methods for Orifice Flowmeters Used in Total Suspended Particle Samplers", for flow calibration of corresponding range air samplers.
2、 Execution standards:
HJ/T368-2007 "Technical Requirements and Testing Methods for Orifice Flow Meter Calibration of Total Suspended Particle Sampler"
IIIProduct features:
1. Small size, light weight, easy to carry, and simple to operate;
2. Built in battery, dual power supply mode of AC and DC, ultra-low power consumption, more energy-saving and environmentally friendly, longer usage time, power consumption ≤ 0.1W.
3. Combining the principle of orifice plate flow measurement with imported high-precision micro pressure sensors, the CPU controls automatic data processing, directly reads flow rate, and automatically converts standard flow rate.
4. Chinese character digital display wide temperature large screen LCD screen, with rich interface display and simple operation.
5. Digitally display numerical values such as operating condition flow rate, standard condition flow rate, atmospheric pressure, ambient temperature, and orifice pressure difference.
6. Using soft switches for power on/off operations and touch sensitive buttons for various operations has a longer lifespan than mechanical buttons.
7. The main components are made of high-strength materials, with holes that are not easily worn and have a long service life. They are equipped with a dedicated aluminum alloy box for easy carrying and use.
8. Equipped with multiple types of adapters, it can calibrate most manufacturers' samplers on the market.
