Hioki 8430-20 10-channel data logger

The Hioki 8430-20 10-channel data logger is palm-sized and can be operated from an AC adapter, rechargeable battery or external battery.

The instrument has 10 fully isolated, analog DC voltage/thermocouple input channels and four digital, pulse counting input channels. Measurement of temperature can be made on live circuits.

On-board data storage provides 3.5 M-words of data on the instrument’s internal 7 MB memory.

Sampling rate for the analog channels is 10 ms as minimum, enabling accurate waveform recording (results stored on Hioki flash card memory - select from 128, 256, 512 MB and 1 GB).

Input voltage ranges are selectable from -100 to 100 mV to -60 to 60 V (full scale max is 100 V). Flash card memory also permits extension of data logging (eg, 327 days of 10 channel plus 4 pulse channel data when sampled every second).

Analog channels can be designated for thermocouple measurement (2000°C full scale) and are suitable for connection of K, J, E, T, N, R, S and B types.

Maximum pulse counting frequency is 5000/s making the digital channels suitable for monitoring rotational speed, angular acceleration and total angle of revolution by integration of pulse counts.

Triggering is selectable for analog and digital channels from rising/falling through preset level or window mode (entering/exiting preset low and high levels).
