HIOKI Memory HiLOGGER Data Logger

HIOKI Memory HiLOGGER Data Logger LR8402-20 - Portable Data Logger with 30 Standard Channels Expandable to 60 Channels

Only the size of an A4 sheet of paper, the HIOKI LR8402-20 is the realization of a goal to build a logger that provides the existing functionality of a multi-channel data logger in a portable format. The new model comes with 30 channel capability as standard, to which another 30 channels can be added. All input channels for measuring temperature, humidity, voltage and impedance are isolated for safety, culminating in a powerful multi-measurement system that also offers pulse and logic inputs. Long-term logging is coupled with the capability to protect data against unexpected power outages and other problems for stable recordings over an entire year (see note). Note: Continuous recordings lasting longer than 1 year are also possible.

Use in Fuel Cell, Electric Vehicle and other Development Applications

■ High Withstand Voltage
The HiLOGGER measures not only fuel cells, but also batteries for UPS (uninterruptible power supplies) devices used in buildings as well as batteries consisting of cells and packaging connected in stacks that require multi-point measurements. In such measurements, high voltage for the whole stack is applied between channel-to-channel and channel-to-ground. Only a measuring instrument with isolated inputs and high-capacity withstand voltage characteristics can endure this.

■ High-Speed Sampling
In the development of automobiles such as electric vehicles (EV) and plug-in hybrid vehicles (PHV) that use motors for propulsion, abrupt changes in load need to be measured. This makes the multi-channel, high-speed 10 ms sampling capability of the LR8400-20 Series an indispensable feature.

■ Multi-Channel Measurements
In the development of fuel cells, multiple power-generating cells are connected to form a stack. Independent measurements of each cell require multi-channel measurements of DC voltage, DC current, temperature and other parameters. The LR8400-20 Series comes with 30 channels as standard, which can be expanded to 60 channels.

■ Environmental measurements to prevent global warming
■ Development of fuel cell materials, energy field
■ Development of automobiles, testing of automobile parts
■ Maintenance and inspection of equipment
■ Monitoring plants
■ Testing of electrical products
■ Impedance testing of electronic parts
