Description
Dickson DT4-150C-B-7-P-1-A Portable Temperature Chart Recorder 0-150C
The Dickson DT4-150C-B-7-P-1-A is a battery-powered portable circular chart recorder designed to measure and log temperature over a 7-day period. It uses a Type A copper thermocouple sensing system (CU A Type SYS) connected via a long capillary probe with a braided metal sheath, allowing remote temperature measurement in refrigeration units, storage areas, ovens, or other environments. The recorder plots readings continuously onto a 4-inch circular paper chart, providing a permanent analog record of temperature over time.

Applications
Dickson portable chart recorders like the DT4 series have long been standard tools for temperature monitoring in environments where a continuous, auditable paper record is required. Typical uses include cold storage and refrigeration compliance monitoring, food service and pharmaceutical storage logging, laboratory incubators and ovens, and industrial process temperature tracking. The 0–150°C range and 7-day chart rotation make this unit well suited for extended monitoring cycles without requiring frequent chart changes. The portable metal case and self-contained battery power allow deployment in locations without AC power, making it practical for field use, mobile cold chain applications, and remote equipment rooms. Dickson has been a recognized name in circular and strip chart recording instruments since the early twentieth century, and the DT4 series represents their analog, battery-operated portable line that saw wide use in regulated industries through the 1980s and 1990s.
This Dickson DT4-150C-B-7-P-1-A Portable Temperature Chart Recorder is being sold as-is for parts or repair. The internal battery is bad due to age and will need to be replaced before the unit can operate. No other testing has been performed, and the recorder is not guaranteed functional in its current state. A calibration label from Micro Quality Calibration (cert 1000331698, dated 01/06/2009) is visible on the case. The capillary probe with braided metal sheath is included.
