Description

PRO 13x.2 – Precision second thermometer, graphic display

INTRODUCTION
PRO 131.2 / 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 statistical calculation.
