1mA to 1000A AC Leakage to Load Current Clamp Meter with 10 µA Resolution in Innovative Flip Design Hioki clamp on meters are best-in-class measuring devices incorporating Hioki’s expertise in current sensing technology. The 3293-50 features a thin and compact clamp core that can measure current between a wide 30mA to 1000A range. The clamp meter is constructed so that the position of the display panel can be adjusted to suit the measuring location, and the back light makes it easy to use even in dark locations.
Classic Earth Resistance Tester Using 3-Pole Method Earthing or grounding of electrical equipment is essential to maintain safety, protecting lives, as well as prevent damage to equipment. The 3151 uses the AC phase differential system to measure earthing resistance, which assures that accurate measurements are unaffected by earth voltage and auxiliary earthing resistance.
Test the Optical Power Integrity of Laser and LED Equipment The 3664 is an optical power meter for measuring the optical power of a spatial light. It is ideal for testing the optical power of a laser light source and an LED light source. The optional optical sensors for the power meter are interchangeable and their sensitivity can be adjusted independently. *This product cannot perform measurement alone. Please purchase an optional light sensor separately. *Use of Optical Sensor 9743/ 9743-10 that are exclusively for blue-violet optical lasers is not supported on earlier versions of Model 3664 (Version 1.01 or earlier). Please visit www.hioki.com to download the Hioki 3664 Setup Utility to enable compatibility of the Optical Sensors with all versions of Optical Power Meter 3664.

Meter Relays
Meter Relays in ±1.5% Class with 1 µA, 10 mV DC Movement for Power Saving Measures and Automation Hioki Meter Relays are industrial 1-channel devices to assist in energy saving and automation implementations. The 2104 series are 1-channel ±1.5% class meter relays featuring a sensitive 1 µA, 10 mV DC movement and a customizable scale. Not CE Marked • 2104H: Lamp lights up and output relay contact operates at deflection of the needle to the right of the setting needle • 2104L: Lamp lights up and output relay contact operates at deflection of the needle to the left of the setting needle • 2104HL: Provides functionality of both H- and L-type models Note: Hioki Meter Relays are built-to-order. Please confirm specifications and delivery time with your local Hioki distributor.
Standard DMM for Electricians, Featuring ±0.3% Accuracy The Hioki DT4200 Digital Multimeter Series consist of a complete lineup of 9 models ranging from professional to industrial to pocket meters, delivering a super fast response rate and safety features that take electrical testing to a higher level. The DT4251 is a digital multimeter designed specifically for electrical work requiring optimal safety, with ±0.3% DC V accuracy, clamp sensor testing, and wide 40 Hz to 1kHz bandwidth.
5kV High Voltage Digital Insulation Resistance Tester Hioki insulation resistance testers or megohmmeters feature all-in-one designs including built-in rugged cases and test lead storage compartments. The 3455 is a 5-range, 250V to 5000V digital insulation resistance tester with bargraph, built-in memory, leak current and voltage testing, and DAR and PI calculation capabilities to help shorten work time associated with field insulation testing.
2-channel Current Logger to Easily Record Load Current of 50/60Hz Lines and Leak Current Hioki compact 1 or 2-channel data loggers feature a 60,000 data set/channel memory to measure temperature, humidity, voltage or instrumentation signals. The LR5051 logs current over 2 channels in as fast as 1 second intervals. Customers using the previous Model 3636-20 Clamp Logger should note that the LR5051 can only record 15,000 points of average data, vs. 32,000 data points available in the 3636-20. Note: Communication adapter LR5091 or Data collector LR5092-20 is necessary to transfer data from a LR5000 series Logger to a PC
World’s First Non-Metallic Contact Voltage Tester Measures 600V With Optimal Safety Hioki leads the industry in non-metallic contact test and measurement technology that promotes safety on the worksite. The 3258 is a line voltage tester that employs a coupling capacitance cancellation method to measure voltage in AC circuits without requiring metal-to-metal contact. Voltage can be measured safely at practically any location, on either insulated or exposed metal conductors.
