MEMORY HiLOGGER 8420-51,8421-51,8422-51
Data Loggers
Internal memory capacity is greatly increased – four times that of previous models!
New multi-channel loggers with enhanced noise immunity
As demand for multi-channel temperature recording for environmental protection, energy conservation and HACCP activities increase steadily, portability to
enable measurement everywhere and at all times, and communications support for
connecting to IT (information technology) networks are becoming indispensable
capabilities for measurement instruments. Furthermore, at measurement sites, accurate measurements are required in severe conditions such as the presence of different electrical potentials, hum noise from commercial power lines, and switching noise from inverters. In response to these requirements, we have developed the
new models with enhanced noise immunity from that of the former models.

Functions upgraded from former models
● Four Times More Internal Memory
● Battery Charging Available During Operation
Internal memor y has been increased from 8 to 32
megabytes in the new models, which can now store up to
about 16.77 million data points.
Previously, the battery could be charged only when the
instrument was turned off, but it can now be charged while
measuring. Because of this, if an unexpected power outage occurs during long-term measurement and recording,
situations such as measurement discontinuation resulting
from battery self discharge can be avoided, significantly
improving the reliability of long-term measurement.
● Enhanced Noise Immunity
The circuitry was reviewed from the ground up, and a deltasigma type A/D converter was incorporated. The effects
of inverter switching noise and 50/60 Hz hum noise that
previously presented problems have been greatly reduced
by the digital filtering function using the oversampling
principle inherent in this type of device.
Note: Optimum noise suppression obtained with recording intervals of two seconds or longer
External Docking Printer
● Improved Accuracy of Internal Clock
Clock accuracy has been greatly improved (0.2 seconds/
day is the same as the previous Model 8422-01).

All input channels are quickly scanned, measured and stored within 100 ms (200 ms or more with channels 17 to 32 in Model 8422-51, and within
about 5 seconds for mixed humidity measurements). As stand-alone instruments, Model 8420-51 provides 4 pulse input channels, plus 8 temperature/
voltage channels, Model 8421-51 provides 4 pulse input channels, plus 16 temperature/voltage channels, and Model 8422-51 provides 4 pulse input
channels, plus 32 temperature/voltage channels. The 32MB of internal memory records about 16.77 million data points.
Real-Time Save to High-Capacity Memory Card
Measurement data can be automatically saved to a PC
Card. Binary (real-time) and text (post-measurement)
formats can be selected. High-capacity Flash ATA
cards up to 1GB can be used for continuous long-term
recording. Choose binary in normal use.This recording
method is linked to writing measurements in real time.

What happens if a power failure occurs while measuring ?
We recommend using the real-time saving function of the MEMORY HiLOGGERs 8420-51, 8421-51 and
8422-51 with a PC Card. This exclusive technology has been developed to preserve data as reliably as possible
even in the event of a power failure by incorporating PC card technology with the know-how built into the
MEMORY HiCORDER series recording instruments. When recording only to internal memory without using a
card, stored data is retained for about ten minutes in the event of a power failure.
Color LCD displays waveforms and numerical values simultaneously, and allows viewing earlier data while measuring
Scroll through the displayed graph while saving
measurements in real time to PC Card to verify earlier
measurements. You can also read the values at the
movable cursors.

LAN Connectivity Supported by PPP Connection to a Telephone Circuit
- Communication Functions The following PC measurements and various web server functions can be employed with a LAN or PPP connection (by connecting the
RS-232C connector through a modem to a telephone circuit or cellular phone).
■ Operation from a PC
• Real-time PC measurement with the optional LOGGER COMMUNICATOR
• Download acquired data from a PC Card or internal memory using the FTP server
• Remote control from a web browser using the HTTP server function
• When communicating with a PC using FTP, acquired data is
transferred only in file units.
• The 9334 software with a LAN connection supports quick
response times as short as 100 ms.
• User-created PC commands necessary to use a direct RS-232C
connection. A direct RS-232C connection allows near realtime measurement data to be obtained with response times of
as little as about a second.
■ Automatic sending from the instrument
• E-mail sending function
• Send data automatically using the FTP client function, or
connect directly to a PC via the RS-232C interface.
Even on a PC equipped only with a USB port, PC
calculations can be performed using a commercially
available USB-LAN adapter.
Remote measurements by HTTP server operation
The HTTP server function can be used to make instrument settings, control
data acquisition and monitor the instrument screen using a common web
browser such as Internet Explorer, without requiring any special software
application to be installed on the PC.
Function Details
• The instrument screen is duplicated in the web browser.
• Key inputs can be made using the same panel configuration as on the actual
• Monochrome/color display and screen refresh rate are selectable.
• The lit/unlit state of the Start LED is refreshed whenever the screen is refreshed.
• By clicking inside the window, the lighting cursor can be moved without having
to use the up, down, left and right arrow keys.
• Start and stop measurement using the web browser.
• Current measurement status can be displayed.
