Purpose:

Mainly used for flow calibration of corresponding range air samplers such as high flow samplers, medium flow samplers, low flow samplers, and semi volatile organic compound samplers, as well as measurement of corresponding range gas flow rates.

Adopting standards:

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

Main features:

1. Adopting high-precision differential pressure sensors and microcontroller technology, the measurement is fast and accurate.

2. Large screen LCD display, Chinese interface, easy to operate.

3. The main components are made of high-strength materials, with holes that are not easily worn and have a long service life.

4. Able to digitally calibrate values such as flow rate, atmospheric pressure, ambient temperature, and orifice pressure difference.

5. It can digitally display numerical values such as working condition flow rate, standard condition flow rate, atmospheric pressure, ambient temperature, and orifice pressure difference.

6. Environmental parameters can be manually entered or automatically measured.

7. Equipped with a large capacity lithium battery, the instrument can work continuously for 12 hours.
