A lot of large trading businesses import products and solutions from us, so we can easily give you the most beneficial price tag with the same quality for anyone who is interested in us.
China Wholesale Magnetic Field Suppliers – LEEM-23 Multifunctional Bridge Experiment – Labor Detail:

Main technical parameters
1. Bridge arm resistance R1: Configure a set of precision resistances: 10Ω, 100Ω, 1000Ω, 10kΩ, which are converted by short-circuit plug connection, and the resistance accuracy is ±0.1%;
2. Bridge arm resistance R2: Configure a set of resistance boxes: 10×(1000+100+10+1)Ω, the resistance accuracy is: ±0.1%, ±0.2%, ±1%, ±2%;
3. Bridge arm resistance R3: Configure two sets of resistance boxes R3a, R3b, which are internally installed on the same double-layer transfer switch, and the resistance changes simultaneously: 10×(1000+100+10+1+0.1)Ω, resistance
The accuracy is: ±0.1%, ±0.2%, ±1%, ±2%, ±5%;
4. Standard resistance RN: The resistance values ​​are: 10Ω, 1Ω, 0.1Ω, 0.01Ω, and the resistance accuracy points
Other than: ±0.1%, ±0.1%, ±0.2%, ±0.5%, can be connected externally;
5. Built-in resistance to be measured: Rx single: 1kΩ, 0.25W, uncertainty: 0.1%; Rx double: 0.2 ohm, 0.25W, uncertainty: 0.2%. These two resistors can be used to calibrate the bridge or test whether the bridge is working properly.
6. Digital galvanometer: use 4 and a half digital display voltmeter: range is 200mV, 2V. The display accuracy of the digital galvanometer is: (0.1% range ± 2 words). Galvanometer can be connected externally;
7. Multi-function power supply: 0~2V adjustable power supply, 3V, 9V power supply.
8. When the instrument is used as a single-arm bridge, the measuring range: 10Ω~1111.1KΩ, 0.1 level;
9. When the instrument is used as a double-arm electric bridge, the measuring range: 0.01~111.11Ω, 0.2 level;
10. The effective range of the unbalanced bridge is 10Ω~11.111KΩ, and the allowable error is 0.5%;
11. When setting up an unbalanced bridge, the instrument needs to be equipped with a resistance sensor or temperature control device.
12. All kinds of similar electric bridges can be customized.
