Precision Resistors for Calibration

Multimeters and resistance boxes need standard resistors for calibration. They require very low temperature coefficient (≤±5ppm/°C) and excellent long term stability (annual drift ≤±10ppm). Hayi Technology's precision resistors for calibration have initial accuracy of ±0.005%. Resistance range is from 0.01Ω to 100MΩ. Power rating from 0.1W to 10W. For example, a metrology lab needed traceable standard resistors. We provided sealed metal case resistors with a calibration certificate. The client said the data matched an imported brand. This case shows Chinese-made resistors can be standard tools. Our MOQ is 1 piece.

Precision Alloy Foil/Wire and Laser Trimming

We use precision manganin, constantan alloy, or foil resistor chips. Our process includes precision winding or etching, thermal aging cycling from -55°C to +125°C, laser trimming to target value, and sealing in a metal or ceramic case with silicone oil. Each resistor is temperature coefficient tested in a constant temperature oil bath. The resistance value is measured with an 8.5 digit multimeter. We hold ISO9001:2015 certification. Each unit comes with a traceable calibration certificate. Our precision resistors for calibration can replace expensive imported standards.

Calibration resistor customers often need parts urgently. Our standard values ship within 1 day. Custom values and packaging take about 15 days. Payment: 30% deposit. Trade terms: EXW, FOB, DDP. If any problem occurs, we talk immediately and improve after we find the cause. We have a dedicated after-sales person. Imported standard resistors are expensive and have long lead times. Our technicians can help you match resistance and temperature coefficient requirements. You can help your client save over 50% on costs.
