Anritsu AP-400 & AP-450 Printing Thermometers
The Anritsu AP-400 and AP-450 printing thermometers produce temperature records directly at the measurement point. Use manual printing for inspection rounds or interval printing to follow temperature changes.
- Built-in printer: Print readings with time information.
- Memory: Store up to 100 readings for batch printing.
- Model choice: AP-400 with ASP connector or AP-450 with ANP connector.
- Probe selection: Match the fixed thermocouple type and connector; probes are sold separately.
Create a paper record while checking temperature with the Anritsu AP-400 and AP-450. The integrated thermal printer allows operators to attach readings to inspection sheets, production records or test reports without using a separate printer.
Choose the instrument and probe together. Connector type, thermocouple type and the probe's operating limits determine which combination suits your measurement.
Printing options for different tasks
- Manual printing: Press PRINT to capture a reading with time information.
- Interval printing: Select one of eight intervals for repeated measurements.
- Numbered printing: Produce sequentially numbered readings for inspection points or samples.
- Memory printing: Store up to 100 readings and print them together later.
AP-400 and AP-450 comparison
| Selection point | AP-400 | AP-450 |
|---|---|---|
| Probe connector | ASP | ANP miniature connector |
| Thermocouple versions | Type E or K | Type E, K, J, T or R |
| Input channels | 1 | 1 |
| Thermocouple selection | Fixed when ordered | Fixed when ordered |
Thermocouple types are not switchable. Confirm the instrument suffix and probe connection before ordering.
Temperature ranges and resolution
| Thermocouple | Instrument range at 1°C resolution | Range at 0.1°C resolution |
|---|---|---|
| E | -200 to 800°C | -104.9 to 504.9°C |
| K | -200 to 1370°C | -104.9 to 504.9°C |
| J | -200 to 1100°C | -104.9 to 504.9°C |
| T | -200 to 400°C | -104.9 to 400.0°C |
| R | 0 to 1760°C | Not available |
The display changes automatically to 1°C resolution outside the 0.1°C range. Always remain within the connected probe's temperature rating.
Instrument measurement accuracy
| Input | Resolution | Temperature | Accuracy |
|---|---|---|---|
| E, K, J, T | 0.1°C | 0°C and above | ±(0.05% of reading + 0.2°C) |
| E, K, J, T | 0.1°C | Below 0°C | ±0.5°C |
| E, K, J, T | 1°C | 0°C and above | ±(0.1% of reading + 1°C) |
| E, K, J, T | 1°C | Below 0°C | ±(0.5% of reading magnitude + 1°C) |
| R | 1°C | 0 to 1760°C | ±(0.1% of reading + 3°C) |
Probe error and reference junction compensation must also be considered when evaluating total measurement accuracy.
Printing interval and battery life
| Printing interval | Sampling rate | Approximate battery life |
|---|---|---|
| No printing | Twice per second | 110 hours |
| 3 seconds | Twice per second | 15 hours |
| 10 seconds | Every 5 seconds | 60 hours |
| 30 seconds | Every 5 seconds | 90 hours |
| 1 minute | Every 10 seconds | 120 hours |
| 5 minutes | Every minute | 8 days |
| 10 minutes | Every minute | 9 days |
| 30 minutes | Every minute | 10 days |
| 60 minutes | Every minute | 10 days |
Battery life varies with operating conditions and printing frequency.
