1、 Overview:

Electronic soap film flowmeter is a device used to measure gas flow rate. It calculates the gas flow rate by measuring the time it takes for the film formed by soap solution to pass through a certain volume of glass tube. The DZL-1 electronic soap film flowmeter measures time and calculates flow rate through its internal microprocessor and photoelectric element combination, and displays it intuitively on the screen. Its accuracy is greatly superior to indirect judgment with eyes and a stopwatch. This instrument is easy to operate, reliable, displays clearly, and has its own advantages in structure and good cost-effectiveness.

2、 Main performance indicators:

Four digit display, capable of displaying battery voltage, time, flow rate, etc;

Measurement accuracy: △ Q<± 1%;

Range: 5-900ml/min;

Equipped with rechargeable batteries, the working time after fully charged is>30 hours;

An external 9V DC power supply is used to charge the battery through an internal charging circuit, with a charging time of 10-20 hours;

Dimensions: Approximately 120 * 95 * 260mm.
