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.

Jandel ResTest Test Ünitesi

(EN) The ResTest is a combined constant current source and digital voltmeter, which has been designed to be used with four point probe equipment to produce resistivity measurements. The unit supplies a constant current and can display resultant voltage sheet resistance and volume resistivity.

Jandel RM3000 Test Ünitesi

(EN) Jandel Engineering Limited offers the RM3000 for use in making four point probe measurements. The RM3000 can supply constant currents between 10nA and 99.99mA, and measure voltages from 0.01mV to 1250mV.
For sheet resistance measurements the quoted range is 1 milliohm/square to 5 x 108 ohms/square. Measurements outside this range are possible but with possible reduced accuracy.
For volume (bulk) resistivity measurements the quoted range is 1 milliohm.cm to 1 x 106 ohm.cm. Measurements outside of this range may be possible but will depend on sample type e.g. whether the sample is a thin layer.
