Amprobe HD110C Heavy Duty Multimeter with IP67 Rating

The Amprobe HD110C IP67 digital multimeter is an average-sensing, manual-ranging meter for measuring current, voltage, and resistance in electrical testing applications with high voltage and harsh environmental conditions. The meter measures alternating current (AC) and direct current (DC) to 2 amp, AC voltage to 1,000 volts (V), DC voltage to 1,500V, and resistance to 20 megaohms. The meter comes with a set of detachable high-voltage test leads and two threaded alligator clips for connecting to high-voltage conductors. The meter's molded plastic case is made from flame-retardant thermoplastic to help protect against fire, chemicals, grease, falls, impacts, and abrasions. The case is sealed to prevent water and dirt from entering and it has an ingress protection rating of IP67, meaning it provides complete protection against dust and is waterproof when submerged up to 1 meter. An audible continuity sensor confirms that the circuit conducts electricity, and a diode test detects whether the circuit's diodes work properly. The hold function keeps a reading on the display, even after the meter is disconnected. An auto power-off mode turns off the unit after 30 minutes of non-use to conserve battery life, and a low-battery indicator signals when the meter's batteries need to be replaced.

This average sensing, or average responding, meter provides accurate readings when measuring linear loads, such as standard induction motors and incandescent lights, where the current or voltage has a sinusoidal waveform. It is a manual-ranging meter and requires that the operator choose the appropriate operating range. The meter has a 2,000-count resolution, meaning it can display up to 1,999 units (3-1/2 digits) before the operating range needs to be changed. It meets International Electrotechnical Commission (IEC) safety standard 61010 and is certified for category IV installations up to 1,000V, which covers measurements at the source of the low-voltage supply, such as electricity meters and overcurrent protection devices. The meter comes with a with a magnetic strap that can be used to hang the meter on metal doors or fixtures and a hex wrench to open the battery compartment door.

Specifications

H is height, the vertical distance from the lowest to highest point; W is width, the horizontal distance from left to right; D is depth, the horizontal distance from front to back.

Multimeters are electrical test meters that measure multiple properties of an electrical circuit, such as current, voltage, resistance, capacitance, and continuity. Available in handheld or benchtop models, multimeters diagnose electrical problems in electrical equipment, wiring, and power supplies. A variety of probes, clamps, and leads can be used to connect the meter to a circuit or device. Multimeters display information either in analog or digital form. Factors that influence meter choice include the electrical properties to be measured, the anticipated range of results, and the desired level of protection against transient voltages. Safety ratings are based on the International Electrotechnical Commission's (IEC) standards for low-voltage test equipment. IEC 61010 delineates four overvoltage installation categories. In general, a meter with a category IV rating will provide more protection against transient voltages than a meter with a lower category rating.
