The Argonne AR-660A High Sensitivity Analog Multimeter is a popular choice among technicians and hobbyists due to its high sensitivity and wide measurement range. Here are some pros and cons of buying this multimeter:

1. High Sensitivity: The AR-660A has a high input impedance of 10 Megohms, which makes it ideal for measuring low voltage and current levels without loading the circuit under test.

2. Wide Measurement Range: It can measure voltage up to 1000V AC and DC, current up to 20A, resistance, capacitance, and frequency.

3. Analog Display: The analog display makes it easier to read and interpret measurements, especially for AC voltage and current readings.

4. Rugged Design: The multimeter has a durable design with a rubberized case and a large dial, making it suitable for use in harsh environments.

5. Ratio Voltage Input: This feature allows for the measurement of voltages that are higher than the full-scale deflection voltage.

1. Limited Functions: Compared to digital multimeters, the AR-660A has limited functions, which may not be suitable for advanced troubleshooting and testing.

2. Calibration: The analog display may require frequent calibration to ensure accurate readings.

3. Limited Input Jacks: The multimeter has only a few input jacks, which may require the use of test leads for some measurements.

The Argonne AR-660A High Sensitivity Analog Multimeter is an excellent choice for those who require high sensitivity and a wide measurement range. Its rugged design and analog display make it suitable for use in harsh environments and for technicians who prefer an analog display. However, its limited functions and the need for frequent calibration may make it less suitable for advanced troubleshooting and testing.

If you require a multimeter for basic troubleshooting and testing, the Argonne AR-660A High Sensitivity Analog Multimeter is an excellent choice. However, if you require a multimeter with advanced functions and digital display, a digital multimeter may be a better option. Ultimately, the choice depends on your specific requirements and preferences.
