LFY-710A Catheter Flow Tester
The main purpose
It is suitable for the measurement of the flow velocity of water flowing through the catheter in a medical catheter under a constant static pressure head. It can also be used to determine the flow velocity of other rigid or semi-rigid fibers that are tubular materials and the water flowing through the catheter.
Instrument characteristics
1. With closed circulating water bath;
2. Equipped with a measuring cylinder to measure the effluent volume of the catheter, with an accuracy of ±1%;
3. The working environment temperature of the instrument must meet (20±2)℃;
Technical index
1. Reagent: distilled water or deionized water;
2. Constant liquid level container provides liquid flow rate (525±25) mL/min, and provides (1000±5) mm height static pressure head;
3. Liquid outflow time: 30s;
4. Power supply: 220V, 50Hz.
