AEMC 5233 [2125.65] True RMS Multimeter with Non-Contact Voltage Detection and Temperature.The Model 5233 is a rugged, economical TRMS digital multimeter with a function for non-electrical contact testing (NCV) function for detecting live electrical circuits. This multimeter is designed for safety: IEC61010, 600V CAT IV. The Multimeter Model 5233 provides a Volt, Ohm, Continuity, Diode, Capacitance, Frequency, Duty Cycle and Ammeter function, as well as an AC voltmeter with low input impedance that is capable of finding ghost voltages by adding a burden to the circuit. It can measure up to 10 Amps directly and can measure temperature in both °C or °F using K-type thermocouples. The rotary function switch provides two OFF positions (OFF and OFF NCV). While in the OFF NCV position, the display will turn red if placed close to a live cable, providing a safe and easy way to detect hot wires. This meter has a high sensitivity with a resolution of 0.01mV and can withstand overloads up to 8000V. The Model 5233 is ideal for electrical installers, electricians and heating or air-conditioning specialists.
