Description
Feature
Simultaneous measurement of four locations
Up to four type-K thermocouple probes can be connected, and the large LCD Simultaneously displays four temperatures from four locations (channels) for easy reading. ASTM (former ANSI) miniature connectors on each thermocouple enable various optional sensors to be connected.
Highly visible display
Measured data are displayed on a large display. Backlight makes it easy to read in dark places.
Logging on SD card
Measured values can be logged on SD card installed in the unit. Attached analysis software “4ch Datalogger for Windows” enables easy graph plotting and data analysis.
Alarm for upper and lower limit temperatures
Different alarm values, both upper and lower, can be set for each of four channels. If the measured value goes out of the set limit value, a buzzer sounds and an LED lamp flashes to alert.
Dedicated analysis software attached
Acquired data can be easily evaluated such as by graph plotting and integration with the software.
Various calculation options available
Maximum, minimum, relative value, temperature difference, and offset function
Fourteen different logging intervals
Available logging intervals: 1, 2, 5, 10, 15, 30 seconds and 1, 2, 5, 10, 15, 30, 60, 90 minutes.
Manual logging, preset logging, memo function
Equipped with manual logging, preset logging that enables you to set the time at which to start or stop logging, and a memo function for quickly logging the current measured value. Can be used for various data collection operations.
AC adapter sold separately
Purchase of an AC adapter is recommended for a long-term measurement.
Fixable on a tripod
A screw hole in the back enables the unit to be installed on a tripod.

Features of attached analysis software
- Imports measured from SD card and performs graph plotting.
- Calculates maximum, minimum, and average values automatically for each channel.
- Calculates integrated temperature. It helps when you analyze accumulated temperature level.
- Marker line function visualizes the points exceeding a certain temperature value or range.
- Saving the data in CSV format enables other spreadsheet software to edit it.
