1、 Execution standards

HJ/T368-2007 "Technical Requirements and Testing Methods for Orifice Flowmeters Used in Calibration of Total Suspended Particle Samplers"

2、 Product Overview

This instrument 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 Flow Meters for Total Suspended Particle Samplers", and is used for flow calibration of corresponding range air samplers. The XA-6002 electronic orifice flow calibrator is suitable for calibrating high flow samplers.

3、 Performance characteristics

1. The instrument host is produced with a standard molded shell, which is beautiful, generous, and compact in size.

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 with wide temperature and large screen LCD display, rich interface display, vivid graphics and text, human-machine dialogue mode, easy operation.

5. LCD brightness adjustment function, easy to read and set parameters, can be manually input or automatically measure temperature and atmospheric pressure.

6. Digitally display numerical values such as operating condition flow rate, standard condition flow rate, atmospheric pressure, ambient temperature, and orifice pressure difference.

7. Maintain the calibration password protection function to prevent non professional users from modifying critical calibration data.

8. 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.

9. We can provide a calibration certificate from the Chinese Academy of Metrology to ensure measurement accuracy.

10. Equipped with multiple types of adapters, it can calibrate most manufacturers' samplers on the market.
