Precise temperature checks in the field need a meter that is easy to read, easy to place and stable enough for demanding work. This handheld family measures with interchangeable 4-wire Pt100 probes via M12 connection, covering -200...+850 °C with 0.01 °C resolution and IEC 60751 linearization.
For daily use, the display adapts to the task: large values, multiline views, min/average/max statistics or a real-time graph. HOLD freezes a reading, REL compares against a user-defined reference, and configurable alarms warn with acoustic or optical signals when thresholds are exceeded.
PRO 115 adds file-based data logging for up to 1 million data sets, including timestamped measurements and CSV export via USB-C mass storage.
The housing supports practical field handling with a foldable stand, integrated magnet, ingress protection IP67 and IK06 impact protection.
Battery autonomy is typically > 150 h.
Predefined calibrated sets offer an accuracy of up to 0.07°C.
The LCD shows large values, multiline measurement views, min/average/max statistics or a real-time graph for the selected parameter.
HOLD freezes the current value on the display. REL shows the measurement against a reference value defined by the user.
Thresholds can be configured with acoustic signaling, optical signaling by flashing backlight and red status LED, and optional hysteresis.
The Pt100 input supports Callendar-Van Dusen parameters R0, A, B and C, plus zero point and gradient adjustment.
The port supports PC connection for COM interface operation. PRO 115 can also appear as a mass storage device for logged files.
The instruments operate with 4 AA alkaline batteries or an external 5 Vdc supply via USB-C, with configurable auto-off and backlight settings.
