Femto / Picoammeter and Electrometer / High Resistance Meter
B2980A Series
Both the picoammeters and electrometers provide a world-best performance of 0.01 fA (0.01 x 10-15 A) current measurement resolution. In addition, the electrometers can measure resistance up to 10 P (10 x 1015 ), which is also a best-in-class specification. Finally, since AC power line noise can be difficult to eliminate when making low-level measurements, both the picoammeters and electrometers are available in battery powered versions.

Surface Resistance Tester
MR – 1
The different specific resistances are specified by selecting one of the pre-programmed materials, or by measuring the specific resistance of unknown materials and entering the result. Preferably the coat thickness is displayed, but the measurement and display of the actual resistance, the square resistance and the specific resistance is possible, too. All measured values can be transmitted into a PC via a serial interface. Controlling the MR-1 on the other hand is not possible.

[5kV AC/6kV DC] Hipot and Insulation Resistance Tester, Rise/Fall-Time Control Function Equipped
TOS5300 Series
The "TOS5300 Series" is a series of test instruments used in Hipot (withstanding voltage) tests and insulation resistance tests, two of the four tests regarded as necessary for ensuring the safety of electrical products. With an output of 5 kV/100 mA (AC) and 6 kV/10 mA (DC), the series can be used in Hipot (withstanding voltage) & insulation resistance testing of electronic equipment and electronic parts, based on the requirements of IEC, EN, UL, VDE, JIS, and other international safety standards and the Electrical Appliance and Material Safety Law. Also, the test voltage stability is improved with the adoption of a newly developed switching amplifier. Since the output voltage can be kept constant even when the AC line voltage or frequency changes, consistent testing can be performed, even when the power supply environment is in an unstable region. The TOS5300 is also equipped with a number of features that are capable of meeting a variety of test needs.
