Description

High Precision Thermometer -PRO111 / PRO115

The PRO 111 and PRO 115 are top-tier professional handheld meters for 4-wire Pt100 probes that offer a wide range of functions, superior ruggedness, and comfortable operation for dependable and safe use.
Additionally, PRO 115 can log data.

FEATURES:
1.Display
The lighting provides ergonomic wide-angle sight from daylight to dark on the multilingual big dot matrix/clear text LCD. It displays the chart of a variable measurement history, statistical data, or big scale values. While the REL feature allows the measurement to be displayed against the measured value, the HOLD feature allows the measurements to be frozen on display.
There are units of measurement in °C, °F, and K. The associated resistance’s display can likewise be turned on and off as needed.
2.Data Logging (only PRO 115)
Large storage capacity: file system-based, up to 1 million data.
By connecting the instrument to a PC via USB, the logged data is stored in easily readable CVS files. The PC views the instrument as a mass storage device, and the data can be read out and assessed without the need for additional software.
Logging automatically with a preset interval.
Each logged sample’s date and time are recorded by the devices’ integrated real-time clock.
3.Alarm
Hysteresis and adjustable alarm thresholds are optional.
When thresholds are surpassed, an LCD indicator and buzzer are activated.

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.

APPLICATIONS

Calibration Laboratories:
Due to their high accuracy (±0.05 °C or ±0.06% of measured value), resolution (0.01 °C), and advanced linearization (CvD and “zero point/gradient”), these instruments are ideal as reference thermometers for calibrating other temperature sensors and devices.
Industrial Process Monitoring:
The rugged, IP67 waterproof design and shock resistance allow for reliable temperature monitoring in harsh industrial environments, such as chemical plants, food processing, and pharmaceutical manufacturing.
Quality Assurance and Validation:
Their ability to log up to 1 million data points (PRO 115), display statistical data (Min, Max, Avg), and provide real-time charting makes them excellent for quality assurance, process validation, and documentation in regulated industries.
Research & Development:
The instruments’ high precision, fast response (2 measurements/sec), and compatibility with various Pt100 probe types (immersion, insertion, mineral insulated) support demanding R&D applications, including material testing and environmental simulations.
HVAC and Building Services:
Suitable for precise temperature measurements in heating, ventilation, air conditioning, and refrigeration systems, ensuring compliance with system specifications and energy efficiency standards.
Field Service and Maintenance:
Their portability, long battery life (>150 h), and flexible mounting (foldable stand, magnet) make them practical for on-site diagnostics, troubleshooting, and preventive maintenance of temperature-critical equipment.
Environmental and Laboratory Monitoring:
The wide measuring range (–200…+850 °C) and data logging capability (PRO 115) enable continuous monitoring and documentation of environmental or laboratory conditions, with alarms for threshold exceedance.
