2-CHANNEL HANDHELD METER / DATA LOGGER
FOR THERMOCOUPLE PROBES
INTRODUCTION
PRO 131.2 and PRO 135.2 are dual channel high class professional handheld
meters for thermocouple probes with a rich set of features, high grade robustness
and operating comfort for safe and reliable use.
PRO 135 also has data logging capability

FEATURES
Display
The multilingual large dot matrix/clear text LCD has ergonomic wide-angle visibility
from daylight to darkness, thanks to the backlight. It displays either large scale
values, statistical data or the chart of a variable measurement history.
The HOLD feature allows freezing the measurements on display, while the REL
feature allows showing the measurement against the measured value.
°C, °F and K units of measurement are available.
If two probes are connected, the instrument calculates and shows the difference
between the measurement of the two channels.
On demand, the display of the internal device temperature (reference junction) can
also be switched on.
Data Logging (only PRO 135.2)
Large storage capacity: up to 1 million data, file system based.
The logged data are store in CVS files that can be easily viewed connecting the
instrument to a PC via USB: the instrument is seen by the PC as a mass storage
device, the data can be read oud and evaluated without software necessarily
needed. Automatic log with configurable interval.
The instruments integrate a Real Time Clock: date and time of each logged sample
are stored.
Alarm
Configurable alarm thresholds and optionally hysteresis can be set. LCD indication
and buzzer activation when thresholds are exceeded.

CONFIGURATION & MEASUREMENT
Probes
Any K, J, T, N, R, S, B and E standard thermocouple probe can be connected.
Wide range of probes available.
Configurable surface correction factors can be set for use in combination with
Senseca contact probes, for the best measuring accuracy.
Connection to PC
Via the USB C port, for viewing or downloading the files stored in the instrument
internal memory (only PRO 135.2) or connecting to the application software
ProXware.
Statistics
Detection of MIN, AVG (average) and MAX. The user can clear the statistical info to start a new statistic calculation
