Schelt Technology

INTRODUCTION
PRO 111 and PRO 115 are high class professional handheld meters for 4-wire Pt100 probes with a rich set of features, high grade robustness and operating comfort for safe and reliable use.
PRO 115 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.
On demand, the display of the corresponding resistance can also be switched on.
Data Logging (only PRO 115)
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 4-wire Pt100 standard probe can be connected, provided it is equipped with an M12 connector.
The high-precision temperature-compensated analog front-end of the meter does not add any significant error to the measurement chain, making the instrument a low-cost high-class reference system.
The sophisticated polynomial sensor linearization gets the best out of your Pt100 temperature probe and provides all relevant possibilities for calibration and adjustment.
Connection to PC
Via the USB C port, for viewing or downloading the files stored in the instrument internal memory (only PRO 115) 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.

Additional Information:

• Delivery Time: 4-6 Weeks
• Packaging Details: Packing will be done in most prominent way so that while delivering product will not get any damage along side we use bubble wrap and soft card board or thermocol support for packaging.

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.

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

INTRODUCTION
PRO 915-2 is a differential pressure and temperature high class professional handheld data logger with a rich set of features, high grade robustness and operating comfort for safe and reliable use.

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.
Many units of measurement available for each measured parameter: pressure, air speed, air flow rate and temperature.
Data Logging
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
Pressure measurement
The meter has an internal ±20 hPa digital differential pressure sensor.
Zero and slope user corrections allows compensating any possible sensor drift with time, for the best measuring accuracy.
Air speed and flow measurement
In combination with a Pitot tube, it can calculate the air speed.
The tube constant is configurable. If air speed measurement in a duct is performed, setting the duct section in the data logger, the air flow rate is also available.
Temperature measurement
The miniature flat-pin input for connecting K-type thermocouple probes allows the instrument to detect the temperature as well.
This feature also allows taking advantage of Pitot tubes with integrated K thermocouple sensor.
Connection to PC
Via the USB C port, for viewing or downloading the files stored in the instrument internal memory 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.
