This manual introduces the specifications, installation, testing, troubleshooting, etc. of the digital reference thermometer (DART) produced by Anderson Instrument Co. Inc.
The Anderson Instrument DART (Digital Reference Thermometer) is designed as a replacement for analog mercury-in-glass thermometers to verify pasteurization temperatures. It features a dual-element temperature sensor with 4-wire circuitry and a 1/2" LED display with 4 1/2 active digits. The device includes fail-safe logic that blanks the display if sensor signals deviate by more than ±0.50°F.
| Calibrated Accuracy (32°F-212°F) | ±0.22°F |
|---|---|
| Calibrated Accuracy (212°F-302°F) | ±0.45°F |
| Speed of Response | Within four seconds |
| Power Consumption | 5 watts maximum |
| Fuse Rating | 1/8 AMP SLO-BLO |
The device is designed to meet response criteria within four seconds for the standard PMO test.
If the sensors deviate by more than ±0.50°F, the logic circuit causes the display to blank.
