The Tecpel DTM-507 is a digital temperature controller that integrates precision dual-channel thermocouple thermometry with an onboard data logger. Rather than actuating a control loop with a PID algorithm, the DTM-507 operates as a supervision controller — it measures temperature from two independent thermocouple sources, records the data over time, and activates an audible alarm via user-settable Hi/Lo limits when thresholds are crossed. This architecture makes it ideal for industrial, laboratory, food, and pharmaceutical temperature monitoring applications where continuous recording and alerting are required.

Measurement & Multi-Sensor Support

• Dual Input Channels: Two independent inputs (T1 and T2) simultaneously display two temperature points or their differential (T1-T2).
• 7 Thermocouple Types: Full support for K, J, E, T, R, S, and N type probes, covering the widest range from -200 °C to 1372 °C (up to 1767 °C with R/S types).
• High Resolution: 0.1°C / 1°C selectable resolution with automatic decimal-point management per ITS-90 temperature standards.

Data Recording & Statistical Functions

• Real-Time Sampling: 128 data records stored with time stamps.
• Structured Logging: Organized into 16 data sets with a maximum total capacity of 1024 data points.
• Statistical Processing: Built-in MAX, MIN, MAX-MIN, AVG, REL, and HOLD calculations for immediate analysis without external software.
• USB Upload: Data transfer to PC via USB interface with optional software and cable for detailed analysis.

Alarm & Control Interface

• Hi/Lo Alarm: Configurable high and low threshold values with an audible beeper alert system, providing essential temperature supervision for GMP and HACCP environments.
• Time & Auto Power Off: Real-time clock with calendar, fully programmable auto power-off timer, and adjustable record interval settings.
