HZND-600 Battery Inner Impedance And Conductivity Meter
I.Overview
As a key component of the power supply system, the battery must be tested and maintained every year, every quarter or even every month, and its test data needs to be analyzed on a regular basis.
At present, the maintenance of valve-regulated lead-acid batteries in China is generally to check the float voltage of the battery. Practice has proved that there is no correlation between the voltage and the capacity, because the voltage only reflects the surface parameters of the battery.
Internationally, the conductivity or internal resistance test has been widely used in the daily maintenance of batteries to replace the voltage inspection method in the past. Because the conductance or internal resistance is a parameter that reflects the internal battery, the conductance or internal resistance of the battery has been recognized as an important parameter for accurately and quickly judging the health of the battery.
The HZND-600 tester is a digital storage type multifunctional portable tester for quickly and accurately measuring battery operating parameters. The meter can display and record important battery parameters such as battery voltage, conductance or internal resistance, connecting strip resistance, etc., through online testing, and accurately and effectively judge the battery's good condition. It can form an intelligent test with a computer and special battery data analysis software. Equipment, further track the decay trend of the battery, and give an alarm in advance to facilitate the discretionary processing of engineering and management personnel.
