PRO111/PRO115, Pt100 4-Wire M12 High-Precision Thermometer for Interchangeable Sensors
PRO 111 and PRO 115 are professional handheld measuring devices for 4-wire Pt100 sensors with a variety of functions, high robustness and ease of use for safe and reliable use.
The PRO 115 variant also has the option of data recording (please select variant when ordering!).
Characteristics:
- For all Pt100 4-wire probes with M12A connector
- Excellent measurement accuracy
- Freely scalable analog output or serial interface
- Zero point/slope input
- Min/max value memory, hold function
- Incl. Calibration protocol
- Delivery without probe and other accessories
- PRO115 variant with data logger
Display:
The large, multilingual dot matrix/plain text LCD display offers ergonomic visibility day and night thanks to the backlight.
It displays either measured values, statistical data or variable measurement curves as a diagram.
The HOLD function freezes the display values, while the REL function shows measured values relative to a comparison value.
The units of measurement °C, °F and K are available.
The display of the underlying resistance value can also be switched on optionally.
Data logger (PRO 115 only):
High storage capacity: up to 1 million data records, file system-based.
The data is stored in CSV files, which can be easily viewed when the device is connected to a PC via USB:
The device is recognized by the PC as a mass storage device, so that data can be retrieved and viewed without additional software.
Automatic logging with adjustable interval.
Real-time clock integrated: Date and time of each recorded sensor are recorded.
Alarm:
Configurable alarm thresholds and optional hysteresis are adjustable.
LCD display and activation of the buzzer when the thresholds are exceeded.
Sensor:
Any standard 4-wire Pt100 sensor can be connected, provided it is equipped with an M12 connection.
The high-precision temperature-compensated analog front end of the meter does not add any significant error to the measurement chain, making the device a cost-effective, top-class reference system.
The sophisticated polynomial sensor linearization gets the most out of your Pt100 temperature sensor and offers all relevant options for calibration and adjustment.
PC connection:
Via the USB-C port, to view and download the files stored in the device (PRO 115 only) or to connect the ProXware application software.
Statistics:
Detection of MIN, AVG (average) and MAX for each displayed variable.
The user can reset the statistical information to start new statistical calculations.
