Description
Sensor
Any K-, J-, T-, N-, R-, S, B and E standard thermocouple sensors can be connected.
Wide selection of probes available.
For use with Senseca contact sensors, configurable surface correction factors can be set to achieve the best measurement accuracy.
Display
The multi-lingual dot-matrix/clear-text LCD-display has an ergonomic wide-angle visibility from daylight to darkness thanks to the background lighting and shows either large scale values or the diagram of a variable measurement profile.
The HOLD function allows you to freeze the readings on the display, while the REL function allows you to display the measured value compared to a user-defined value
If two sensors are connected, the data logger calculates and displays the difference between the measured values of the two channels.
The units °C / °F are available.
Data logging (PRO 135 only)
Large storage capacity: Up to 1 million data, file system-based.
The recorded data is stored in CVS files, which can be easily viewed when the device is connected to a PC via USB: The device is seen by the PC as a hard disk unit, no additional software is required.
Automatic recording with configurable interval.
The devices have a built-in real-time clock: The date and time of each recorded sample are stored.
Application software
In addition to CSV files, a free, easy-to-use basic PC application software allows you to examine a large amount of recorded data, with the ability to display each recorded variable at a user-selectable interval.
Alarm
Configurable alarm thresholds and optionally a hysteresis can be set. LCD display and buzzer activation when thresholds are exceeded
Statistics
Acquisition of MIN, AVG (average) and MAX for each displayed variable. The user can delete the statistical data to start a new statistical calculation.
PC connection
The USB-C connector allows you to view or download the files stored in the device's internal memory (PRO 135 only) or connect to the application software.
Power Supply
4 powerful AA-batteries, the power-saving design and the configurable automatic switch-off function ensure a long operation. For continuous operation, the device may also be supplied with power through the USB-C connection. Any commercial 5 Vdc power supply or a PC USB connection can be used.
Configurable LCD-background lighting for more power saving options.
Ergonomics
The design allows one-handed operation as well as use on the table with a folding back stand.
Side rubber protection offers a secure grip while using in the field.
