Jandel HM21 Test Ünitesi

(EN) Jandel Engineering Limited offers the HM21 for use in making four point probe measurements. The HM21 has six constant current settings between 100nA and 10mA, and measures voltages from 0.01mV to 1250mV.
For sheet resistance measurements the quoted range is 1 ohm/square to 10 Megohms/square. Measurements outside this range are possible but with possible reduced accuracy.
For volume (bulk) resistivity measurements the quoted range is 10 milliohm.cm to 10 Kohm.cm. Measurements outside of this range may be possible but will depend on sample type e.g. whether the sample is a thin layer.
