Handheld 10-channel Data Logger with 10ms Simultaneous Sampling Hioki Memory HiLoggers are high-speed data loggers for recording multiple chanels of voltage, temperature, pulse or rotation signals, providing complete isolation between channels and strong noise resistance . The LR8431-20 logs data at 10ms speeds across 10 channels simultaneously, and features a bright color LCD for crystal clear waveform displays. Note: The LR8431-20 is not bundled with the Battery Pack 9780. Thermocouples are not provided by HIOKI, and must be purchased from a separate vendor. Note: Use only HIOKI CF cards, which are manufactured to strict industrial standards, for long-term storage of important data. Correct operation of non-HIOKI CF cards or USB memory sticks is not guaranteed

Handheld 30- to 60- channel Data Loggers with 10ms Simultaneous Sampling Hioki Memory HiLoggers are high-speed data loggers for recording multiple chanels of voltage, temperature, resistance, humidity and pulse signals, providing complete isolation between channels and strong noise resistance. The LR8400 Series logs data at 10ms speeds across 30 channels simultaneously, is expandible up to 60 channels, and features a bright color LCD for crystal clear waveform displays. • LR8400-20 (with built-in Votage/temp unit× 2) Built-in units are equivalent to the Votage/temp unit LR8500 (15 ch) × 2 • LR8401-20 (with built-in Universal unit × 2) Built-in units are equivalent to the Universal unit LR8501 (15 ch) × 2 • LR8402-20 (with built-in Universal unit × 1, Votage/temp unit × 1) Built-in units are equivalent to the Universal unit LR8501 (15 ch) × 1, and Votage/temp unit LR8500 (15 ch) × 1

600-channel Data Logging System with 10ms Sampling Hioki Memory HiLoggers are high-speed data loggers for recording multiple chanels of voltage, temperature, resistance, humidity, rotation, and pulse signals, providing complete isolation within channel sets. The 8423 with optional input modules log data at 10ms speeds across up to 600 simultaneously, and is configurable and controllable using a PC. Note: 8423 cannot operate alone. You must install one or more optional input modules in the unit. Thermocouples are not provided by HIOKI, and must be purchased from a separate vendor.

3-Phase 4-Wire Portable Energy Loggers for Energy Audits and Energy Conservation HIOKI Clamp On Power Meters are multi-channel power measuring devices utilizing clamp sensor input to accurately and safely measure power on single-phase to three-phase lines. The PW3360-20 and PW3360-21 monitor power demand and other power parameters to aid in energy audits and validate energy saving measures. • CLAMP ON POWER LOGGER PW3360-20 (Main unit only) • CLAMP ON POWER LOGGER PW3360-21 (Harmonic analysis model) Note: At least one optional current sensor is necessary to measure current or power parameters. To store measurement data, use only the guaranteed SD cards sold by HIOKI.

1-channel Temperature Logger with -40°C to 180°C range 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 LR5011 logs temperature over 1 channel in as fast as 1 second intervals. Note: Communication adapter LR5091 or Data collector LR5092-20 is necessary to transfer data from a LR5000 series Logger to a PC

2-channel Temperature and Humidity Logger with -40°C to 85°C range 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 LR5001 logs temperature and humidity over 2 channels in as fast as 1 second intervals. Note: Communication adapter LR5091 or Data collector LR5092-20 is necessary to transfer data from a LR5000 series Logger to a PC

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

1-channel DC Voltage Loggers to Record Instrumentation Signals and Measure Analog Output from Sensors and other Devices 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 LR504X series logs DC voltage over 1 channel in as fast as 1 second intervals, available in three different ranges. • LR5041 (±50mV DC), • LR5042 ( ±5V DC), • LR5043 (±50V DC) Note: Communication adapter LR5091 or Data collector LR5092-20 is necessary to transfer data from a LR5000 series Logger to a PC
