1、 Product Overview:

The BX-7000 comprehensive pressure and flow calibration instrument (hereinafter referred to as the calibration instrument) integrates micro pressure, gauge pressure, small flow, medium flow, and large flow calibration. It has high calibration accuracy, is easy to carry, and can meet the flow calibration of most sampling instruments. It is an essential instrument for calibrating various sampling instruments with multi range flow and pressure.

It can be widely applied to metrological verification, environmental monitoring, labor protection and health, scientific research institutes, and other occasions that require gas flow calibration. There have been significant improvements in terms of quantity stability, greatly reducing labor intensity.

2、 Product features:

1. Adopting an industrial grade 5-inch color display screen, the operation is more convenient.

2. One machine is versatile and can calibrate the flow rates of gases, dust, and smoke in various ranges. It can also calibrate micro pressure and gauge pressure;
3. Directly read traffic, automatically convert standard traffic, and read directly;
4. It can be manually inputted or automatically measured for temperature and atmospheric pressure;
5. Chinese character digital display, wide temperature large screen LCD display, rich interface display, graphic and textual human-machine dialogue mode, simple operation.
6. Dual use of AC and DC, built-in high-energy lithium battery, dual power supply mode of AC and DC.
7. Large capacity data storage and querying, as well as external printing or computer connection for data communication.
8. Built in pressure generator and membrane flowmeter are convenient to use.
9. The built-in soap film tube has a plug-in top cover, which can be pulled out to clean the soap film tube and ensure measurement accuracy.
10. Equipped with multiple types of adapters, it can calibrate most manufacturers' samplers on the market.
