HIOKI LR8431/LR8432 10-Channel Dataloggers with USB Flash Drive
The HIOKI LR8431-20 and LR3432-20 are high-speed data loggers for recording multiple chanels of voltage, temperature, pulse, or rotation signals. They features a bright color LCD for crystal clear waveform displays. Moreover the loggers offer complete isolation between channels and strong noise resistance.
The LR8431 logs data at 10 ms speeds across 10 channels simultaneously. The LR8432 also has 10 channel and is specialized for heat flow measurement. The heat flow logger is ideal for evaluating insulation performance and analyzing the causes of temperature change.
- 10 isolated analog and 4 pulse input channels for voltage, temperature (thermocouples), totalized pulses, and rotation count.
- 10 ms sampling and recording across all channels.
- Record measurement data on a USB flash drive for easy transfer to a computer.
- Record to reliable Compact Flash cards during long-term measurement applications for increased peace of mind.
- Replace storage media during real-time recording.
- Ultra-compact for convenient portability.
- Widescreen, bright LCD gives excellent viewability.
- HIOKI LR8431:
Improved thermocouple measurement accuracy and reference junction compensation accuracy. Noise-resistant measurement circuitry for improved readings. - HIOKI LR8432:
Use a heat flow sensor to measure the movement and volume of heat energy. Record raw waveforms and post-calculation waveforms at the same time (heat transmission coefficient processing). Two graduations can be displayed with a double gauge.
Principal applications:
Automotive market (evaluating the flow of heat into the vehicle interior from the engine compartment, assessing heat damage to vehicle parts, identifying sources of heat, etc.).
Residential construction market (evaluating the insulation performance of building materials, evaluating the performance of radiant heating systems, etc.).
