MEMORY HiLOGGER LR8431
**This compact logger excels in a broad range of settings, from production lines to research and development**
## **Evaluating motors and inverters used in electric and hybrid vehicles**
The LR8431 achieves high speed measurements, isolated inputs, and stable measurements that are less affected by noise
## **Efficiency measurement and performance evaluation of air conditioning equipment**
The LR8431 supports simultaneous, multi-point measurement, for example of input and output at multiple air conditioners or the temperature of internal components
**Temperature measurement and performance evaluation of internal components in electronic equipment**
Used with a wind velocity converter, the LR8431 can measure cooling efficiency inside equipment enclosures

## **Ten Isolated Analog Input Channels**
There’s no need to worry about differing potentials of measurement objects when measuring temperature and voltage. All ten analog channels are isolated. Even when measuring temperature and voltage at the same time, interchannel interference and electric shock hazards are eliminated. The four pulse channels are ideal for counting revolution pulses to measure rotation speed. (Pulse inputs share common ground.)
Note: Isolation between channels is possible through the use of semi-conductor relays. Voltage exceeding the product specifications, such as that originating from lightning surges or other sources, should never be applied between each channel; otherwise the relays will short and the recorder will be damaged.
## **High-Speed Sampling**
## 10 ms Sampling and Recording Across All Channels
Abrupt changes in load need to be measured during development of EV[• ] HV[• ] PHV, for which multi-channel, 10 ms sampling is essential. This HiLOGGER can track waveforms that could not be followed with the 100 ms sampling interval previously available.

## **Enhanced Noise Suppression**
## Noise-resistant measurement circuitry for improved readings
Measurement involves the deployment of a delta-sigma type A/D converter. Suppress inverter switching noise and line-frequency hum by digital filtering with the HiLOGGER's proprietary oversampling technology.
Note: Optimum noise suppression is obtained for recordings at least two seconds long.

## **Easy and convenient measurement of heat flow**
The measurement of heat is useful for achieving more accurate air conditioning control and implementing measures against heat during product development. UA |
With temperature fluctuation, there is always a migration of heat. Heat is energy that causes a change in temperature, and it moves from high to low in the same way as water and electricity.
The degree of this migration is referred to as "heat flow” and is expressed as the amount of heat energy that flows through a given area over a given period of time (units: W/m[2] ).
Temperature is the result, while heat flow is the process. Temperature fluctuation (heat generation or absorption) cannot be understood solely through temperature measurements using thermocouples and thermography.
To get the complete picture, use a heat flow sensor to visualize the movement and volume of heat energy as a leading indicator of temperature fluctuation.
Measure multiple areas where heat is generated in order to combat heat sources in a variety of consumer electronics.
Measure the flow of heat in human bodies to understand the conduction efficiency of heat in materials and fabrics under development.
Applicable to the development of bathroom floor materials and clothing
Regularly diagnose the heat flow of thermal insulation material used to understand the deterioration of thermal insulation performance over time.
Predict room temperature management in greenhouses affected by external temperature fluctuation.

## **Simple settings for the heat flow sensor**
Avoid troublesome calculations by directly entering the sensitivity of the heat flow sensor.
Use segmented calculations to determine and save average values and maximum values for each time block (units: minutes).
## **Display heat flow and temperature gauges simultaneously**
Display the gauges for data you want to compare at the same time in order to see changes in temperature and heat flow at a single glance.

- _For more reliable data protection, we recommend use of HIOKI CF cards which are manufactured to strict industrial standards, for real-time data save or long-term storage of important data. Media other than CF cards, which are HIOKI genuine options, are not guaranteed to work._
- _USB communication function and saving to USB memory are not available at the same time._
- _Maximum recording time is inversely proportional to number of recording channels._
- _Because the header portion of waveform files is not included in capacity calculations, expect actual maximum times to be about 90% of those in the table._
