The Hioki HPK-2 professional HVAC and electrical test kit includes a pen-sized digital multimeter, infrared thermometer, digital clamp meter, phase tester, and noncontact voltage detector for installing, repairing, and maintaining commercial and residential electrical and heating, ventilation, air-conditioning, and refrigeration (HVAC/R) systems. The kit comes with instructions and batteries for all components and one test lead set each for the clamp meter and phase tester. A hard plastic carrying case with foam cutouts stores and organizes the contents of the kit when not in use and has a latch for securing the lid during transport and storage.
The Hioki 3246-60 digital multimeter (also known as a multitester) has integral test leads that measure voltage and resistance, and a built-in light that illuminates dark work areas. The pen-sized meter fits in a shirt pocket when not in use. An audible continuity sensor confirms a circuit conducts electricity, and a diode test detects proper functioning of a circuit’s diodes. The hold function keeps a reading on the LCD, even after the meter is disconnected. The LCD is backlit for readability in low light. The black test lead can be attached to the back of the meter and the red test lead can be covered with the built-in sensor cap to help protect against bumps and abrasions during storage and transportation. It is an average-sensing, or average-responding, meter that provides accurate readings when measuring linear loads with an undistorted waveform. When turned on, the meter is in auto-ranging mode and automatically selects the correct operating range for the property being measured. It can be switched to manual-ranging mode, which allows the operator to choose the appropriate operating range.
The Hioki 3280-10 digital clamp-on multimeter has a clamp with two jaws that can close around an electrical conductor up to 33mm (1.3 inches) in diameter to measure current without touching or interrupting the circuit. The meter comes with detachable test leads for measuring voltage and resistance and for testing continuity to confirm a circuit conducts electricity. The LCD shows readings in digits and on a bar graph and is backlit to provide readability in low light. The hold function keeps a reading on the display, even after the meter is disconnected. A finger guard on the body of the meter helps protect fingers from shock. The meter can survive falls of up to 1 meter to a hardwood or concrete floor. It is an average-sensing, or average-responding, meter that provides accurate readings when measuring linear loads with an undistorted waveform. When turned on, the meter is in auto-ranging mode and automatically selects the correct operating range for the property being measured. It can be switched to manual-ranging mode, which allows the operator to choose the appropriate operating range.
The Hioki 3419-20 infrared digital thermometer measures surface temperature at a distance for applications involving hard-to-reach, moving, hot, or electrified equipment. The thermometer has an 8:1 distance-to-spot ratio, which means the measurement field measures approximately 8 feet in diameter when the target is 1 foot away. A built-in laser pointer helps improve aiming accuracy when taking measurements, and it has an adjustable emissivity setting to help improve measurement accuracy on a range of surface types. The LCD shows present temperature and highest or lowest temperature reading for the session. The screen is backlit for visibility in low light. Readings can be stored in the thermometer's internal memory for future recall, and the user can set an alarm to sound when readings exceed or drop below preset limits.
The Hioki 3129 phase sequence tester helps ensure proper connection to an electrical device or a 3-phase alternating current (AC) power supply. It indicates the phase sequence of a 3-wire installation and checks for live voltage in electrical lines. A test lead set with three nonmetallic static-induction voltage clips is included. The clamps can be attached to insulated wires, helping reduce the risk of shock to the operator due to contact with exposed wires or conductors. The clamps can accommodate wires from 2.4 to 17mm (0.09 to 0.67 inches) in diameter, and the test leads are 0.7m (27.56 inches) long.
The Hioki 3120-21 noncontact voltage detector senses AC voltage without touching or disconnecting the circuit, helping to protect the operator from shock by identifying live wires and cables.
