BX-7100 electronic orifice flow calibrator
1、 Product Overview:
The BX-7100 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"
3、 Product features:
1. One machine is versatile and can calibrate both medium and high flow samplers by simply selecting calibration components.
2. Small size, built-in battery, AC/DC dual-use, easy to carry and use.
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. The instrument display adopts a LCD screen, Chinese menu, and simple operation.
