DTMA-101 Portable Thermometer Readout
The DTMA-101G portable thermometer readout is a high-precision instrument designed for metrology, research, and industrial applications. Compatible with various sensors, it offers advanced features like automatic data correction and traceable history, delivering reliable performance across demanding temperature measurement tasks.P
Multi-point correction: 8-point correction is supported. Correction values are stored and auto-matched to the connected sensor. Dates of correction are automatically recorded.
Real-time data curve display: Displays the most recent 200 data curves to support trend analysis.
Multi-unit display: Temperature is shown in °C, K, °F, and resistance in Ω, with max, min, average, and stability values displayed in real time.
Calibration modes: Calibration can be completed using 1-point, 2-point, or 3-point mode. Calibration dates are automatically recorded for traceability.
Built-in sensor parameter database： It ensures accurate measurements across a wide range.
Alarm notification： Visual alarm triggers when measurements exceed user-defined thresholds.
Anti-mistouch design： Prevents accidental parameter changes. Allows the user to freeze the current data display for easy recording.
Customizable sampling interval： Users can configure the data acquisition interval to match different application requirements.
Standards compliance： Fully compliant with the ITS-90 international temperature scale, and supports Pt sensors with alpha values of 0.00385 (385), 0.003911 (3911), 0.003916 (3916), and 0.003926 (3926), ensuring high compatibility and reliability.
Custom sensor support： Sensor customization is available to meet specific environmental or application needs.
