Description

Differential Manometer / Thermometer-PRO 915-2

INTRODUCTION
PRO 915-2 Manometer / Thermometer 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.
