TH0330 Ultra-Stable Resistance Standard

1. Summary

TH0330 is a series of standard resistance with ultra-high precision and stability, using new stress-free technology and has excellent long-term stability and extremely low temperature coefficient. With good anti-moisture and anti-oxidation properties, it can be used directly in the air. This type of resistance can be used with precision I/I conversion standards and precision voltmeters to achieve a wide range of precision current conversion measurements. It is also suitable for the calibration of precision transformers, sensors, measurement laboratory resistors, high-precision resistance meters, multi-function calibrators and high-precision digital multimeters.
