ZHK2503N Gas Flowmeter

Multi-use: The main unit can be used with five  different ranges of soap film flowmeters, seven  different ranges of orifice flowmeters, and three  different ranges of mass flowmeters. 

Touchscreen Color Display: User-friendly  interface and simple operation. 

Automatic Display of Conditions: Can automatically display volumetric flow rates under four  conditions: current conditions, standard conditions (273.15K, 101.325kPa), standard conditions (293.15K, 101.325kPa), and standard  conditions (298.15K, 101.325kPa).

Digital Calibration Capability: Capable of digital  calibration for flow, pressure, environmental  temperature, time values, and battery level. 

Data Storage Function: Can store 80 data points  per range.

USB Interface: Option to add a USB drive for data  export.

Bluetooth Printer Option: Supports wireless  communication between the printer and the main unit. 

Manual Input Capability: Allows manual input of  standard atmospheric pressure and environmental  temperature values to minimize measurement errors  caused by automatic sensor measurement. Built-in Lithium Battery: Battery life exceeds 8 hours. Battery Level Display and Over-discharge Protection. 

Soap Film Section: The soap film flow detector utilizes an infrared  sensing device combined with microcomputer data  processing technology, ensuring high measurement  accuracy and effectively reducing human errors.

The soap film tube has good light shielding properties, preventing sunlight interference and ensuring  high reliability.

Capable of automated calibration of soap film volume  values. 

Can automatically record and display the flow values  for N measurements (unlimited times), and automatically calculate the average flow of the N measurements.

Orifice Section: Utilizes a high-precision differential pressure sensor  for real-time measurement and display of gas flow.

Application

Suitable for flow calibration and verification of large, medium, and  small flow particulate samplers, atmospheric/smoke/dust samplers,  VOC samplers, gas chromatography, float flowmeters, mass flowmeters, and other instruments.

Mass Flowmeter Section: Utilizes a high-precision mass flow sensor for real-time  measurement and display of gas flow.
