Product Description
- Commodity name: Oil filled constant temp. standard resistance
- Commodity ID: AR-1270A
The AR-1270A(B) oil filled constant temperature produced by AIKOM company is a standard resistor with a built-in thermostat. The A-type is equipped with a low noise power supply, using oil filled inner chambers, high-level resistance components, and low thermal potential terminals. The components have undergone over 6 years of aging and temperature aging from 0℃ to 46℃. Type A has undergone at least 1 year of testing in the factory, while Type B has undergone at least 6 months of aging in the factory. It is a standard measurement device for high-level temperature measurement bridges in temperature and electrical laboratories.

Application areas
Suitable for use in air environments, with built-in constant temperature function, not affected by environmental temperature. It can be used as a working standard by simply plugging in the power supply, and can also be used as a high stability and high reliability comparison and calibration device.

Product characteristics
•Filling the inner chamber with oil can reduce the impact of temperature changes on the resistance, and isolate the air to reduce the impact of humidity on the accuracy of resistance measurement, thus ensuring its high stability.
•Using low thermoelectric potential terminals to reduce the impact of thermoelectric potential.
•Type A is equipped with a low noise power supply (requiring long-term constant temperature) to reduce interference caused by power supply, and can simultaneously power 8 standard resistors. Type B is an optional accessory. -
