Product Description

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.

2. Features
1.Nominal resistance value: 1 Ω ~ 1 kΩ (4 in total)
2.Using stress-free metal foil technology
3.Long-term stability: typical value 0.2 ppm/year
4.Low temperature coefficient: 0.05 ppm/ºC@ (23ºC±5ºC)
5.Moisture resistance: 0.1 ppm/% RH
6.Pressure coefficient: 0.001 ppm/hpa
7.Adopt low thermoelectric potential and good structural design
8.Can be used directly at room temperature (18ºC ~ 28ºC)
9.Small size and light weight

3. Applications
1.Calibrate high-precision resistance meter
2.Establish a precision current measurement system
3.Standard resistance value transfer

☆ Calibrate standards/precision resistors

TH0330 can be used with precision resistor bridges such as TH0210 to achieve transfer calibration of standard resistors (first and second class).

  

☆ Establish a precision current measurement system

TH0330 can be used with DC I/I conversion standard (ratio standard) and precision voltmeter to form a precision DC current measurement system.
 

Note: When measuring current, the maximum operating current of the standard resistor should not be exceeded; for precision current measurement, the influence of factors such as the resistor's rated power and power coefficient should also be considered.
