Used KEITHLEY 225 #9240273 for sale

KEITHLEY 225 is a versatile and reliable digital multimeter designed for use in a wide range of electronic tests. The meter has a wide range of measurements that can be performed including DC and AC volts, resistance, current and temperature. The testing capabilities have been further expanded with the inclusion of four selectable resistance ranges (1, 10, 100 ohms and 1 kohm) as well as overvoltage protection. In addition, the instrument has two LED displays for measurement results and two selectable modes of operation, for manual or continuous operation. 225 works by connecting it to the device under test, and having a sample-and-hold feature makes the accurate voltage and current measurements. It has AC voltage input to measure AC voltage up to 750V together with DC voltage input to measure DC voltage up to 1000V. The input impedance is 10 megohms, so delicate signals can be measured without fear of them dropping off or diminished. The resistance range extends from 0.1 ohms to 200 Mohms, and the current measurement range extends from 1uA to 3A. It has the additional feature of allowing the user to select a lower current resolution for currents below 1 mA. KEITHLEY 225 can measure temperature with its internal thermocouple. This feature allows the user to accurately measure the ambient temperature as well as the temperature of any coolers or heaters within the equipment under test. The thermocouple interface can be used to accurately measure temperature up to 750 °C. 225 is equipped with a special testing feature known as diode testing. This feature allows for the testing of transistors as well as diodes. By setting the test voltage, the user can determine if the device under test is operating correctly, as well as directly measure any leakage current. KEITHLEY 225 is designed to withstand a wide range of environmental conditions, including shock, vibration, and humidity. It also meets stringent safety standards and is RoHS compliant. In summary, 225 is an all-in-one device that enables user to perform a wide range of digital/electronic tests and measurements. With its wide array of measurement ranges and functions as well as its superior accuracy and resolution, it is an ideal instrument for many testing and measuring applications.
