JH-61 Handheld Smoke Flow Rate Monitor [Temperature Pressure Flow]

1、 Product Overview

JH-61 type flue gas flow velocity detector (hereinafter referred to as the detector) is a high-precision portable flue gas flow velocity detector widely used for measuring parameters such as flue gas flow velocity, flue gas flow rate, standard dry flow rate, dynamic pressure, static pressure, and flue gas temperature in boilers, furnaces, and various exhaust ducts.

JJG 518-1998 "Verification Regulations for Pitot Tubes"

GB/T 16157-1996 "Determination of particulate matter and sampling methods for gaseous pollutants in exhaust from stationary sources"

2、 Scope of application

This instrument uses the pitot tube method to measure gas flow velocity in pipelines, and can detect various parameters such as flue gas flow velocity, flue gas flow rate, standard dry flow rate, dynamic pressure, static pressure, and flue gas temperature in boilers, industrial furnaces, and exhaust ducts. The instrument uses imported high-precision sensors, and the sensor's 24-hour self drift is less than 0.15Pa, making it particularly suitable for monitoring low flow velocity in flue gas ducts.

3、 Performance characteristics

1. Adopting imported high-precision micro differential pressure sensors, the pressure drift within 24 hours is less than 0.15Pa.;

2. The measurement accuracy of flow velocity is high, and the lower limit of determination can reach 0.3m/s;

3. Equipped with a rechargeable lithium battery, it can work continuously for more than 48 hours on a single charge;

4. Handheld measurement monitor, lightweight and portable, easy to operate;

5. Automatically calculate parameters such as average gas flow rate, average pressure, and flue gas flow rate.

6. It has automatic zero point correction and software calibration functions to ensure measurement accuracy;

7. It has the function of setting up smoke ducts, automatically recommending sampling points and measuring point distances;

8. Large capacity data storage, capable of storing 800 sets of data files;

9. Wide temperature LCD display with Chinese operating interface;

10. Large size, wide temperature, high brightness color display screen display;

11. It has power failure protection function, and the sampling data is not lost during power failure sampling;

12. Built in Bluetooth module, optional Bluetooth printer for data printing.
