Data Logger MIJ-01
- Work 350 days with mounted 4AA alkaline batteries.
- Individual 8 Ch.150mA capacity pre-heat output
(Excitation out put for drive many kind of sensors)
- Analog inputs of DIFF8ch (SE16ch) equipped with zero-crossing 2ch, rain gauge pulse 4ch and RS232C /2ch. 5ppmTCXO is used for time stamp.
- Additional calibration was done using satellite 1pps pulse at factory calibration 24 bit AD converter (effective 18bit).
- Micro SD Memory card slot mounted on MIJ-01; No need to think about memory limit.
- External power supply accept DC12V many kind of batteries
- PC requires USB cable for connecting PC
(USB cable supplied with MIJ-01)
- Sized almost same as spread passport size
- Easy installation to Pelican1120 water proof box
(Optional or user can buy everywhere)
MIJ-01 is developed to proposition for high precision, high resolution, multi channel, large data capacity, small size, lightweight, energy saving, and usefulness . Thus, MIJ-01 can support Diff 8ch, Zero-cross, pulse, and serial input; and it can also last long with only 4 AA battery.
Not only these but using Option MUX32/64 MultiPlexer, it can enhance the number of channels up to DIFF64 channels and 128 Single end channels; which mean it can be able to use on a small scale as stand alone to extensive measurements scale.
|Input Range||Resolution||Error Rate|
|DIFF ±5000 mV||0.01mV||±0.02%F.S.|
|SE 0 to +5000mV||0.01mV||±0.03%F.S.|
|DIFF ±1250 mV||0.01mV||±0.05%F.S.|
|SE 0 to +1250mV||0.01mV||±0.05%F.S.|
|DIFF ±15 mV||0.1 micro V||±0.04%F.S.|
|SE 0 to +62.5mV||0.1 micro V||±0.04%F.S.|
Support T and K type thermocouple when On-board IC thermistor + aluminum block set as Cold junction .
Precision of cold junction temperature ±1.0℃
Guaranteed ±5 ppm, since using TCXO crystal oscillator
