Product advantages

RMHI-3000Ultra low micro resistance tester for high-temperature materials

3 major features

1能以1 n Ω high-resolution measurement of low resistance

2Low cost, space saving, multi-channel

3Can be integrated into automatic detection equipment

1能以1 n Ω high-resolution measurement of low resistance

Measure resistance by measuring the current flowing through objects such as welding parts. Select qualified and unqualified products based on the difference in resistance values. When the welding resistance is low forAbout 10 μ Ω~100 μ Ω.

RMHI-3000Ultra low micro resistance tester for high-temperature materials

equipThe range of 1000 μ Ω enables high-precision measurement of low resistance with a resolution of 1 n Ω. When welding is insufficient, the resistance value will be higher than that of qualified products. Measure the slight difference in resistance values between qualified and unqualified products to determine whether they are qualified or not. By numerically managing the welding quality of all products on the production line, traceability is ensured.

Models with built-in multiplexer RMHI-3000Ultra low micro resistance tester for high-temperature materials

2In addition, with the scanning module rackWhen used in combination with SW1002, it can support up to 132 channels (4-terminal method). This low-cost and space saving system can meet the needs of multi-channel measurement.

3Can be integrated into automatic detection equipment, No need to consider wire resistance and contact resistance

The tolerance range of circuit resistance has been expanded, so there is no need to consider wire resistance or contact resistance It is integrated into the system. standard configuration LAN communication interface is also standard for data connection with devices such as PC or PLC.

Convenient features

No need to zero

Accuracy can be guaranteed without preheating or zeroing, Measurement can start immediately after startup.

Offset voltage compensation function（OVC）

When encountering thermoelectric magnetic fields or internal offset currents in instruments Under pressure conditions, it will automatically adjust and compensate, To reduce measurement errors.

Contact inspection function

Detecting erroneous measurements caused by contact errors, Reduce the risk of misjudgment and missed detections.
