Accurate temperature measurement is critical in virtually every laboratory process — from chemical reactions to biological incubations and QC testing. Choosing the right thermometer ensures data integrity and reproducibility.
Types of Lab Thermometers
| Type | Range | Accuracy | Application |
|---|---|---|---|
| Liquid-in-Glass | -200 to +600°C | ±0.1 to ±1.0°C | General lab, melting point, distillation |
| Digital RTD (Pt100) | -200 to +850°C | ±0.05 to ±0.3°C | High-precision QC, calibration standards |
| Thermocouple (K-type) | -200 to +1350°C | ±0.5 to ±2.0°C | High-temperature furnaces, ovens |
| Infrared (IR) | -50 to +1000°C | ±1.0 to ±2.0°C | Non-contact, rapid measurement |
| Thermistor | -50 to +150°C | ±0.1 to ±0.2°C | Incubators, water baths |
Calibration Best Practices
- Frequency — calibrate at least annually, or quarterly for high-precision work
- Points — use at least two calibration points (e.g., 0°C ice bath and 100°C boiling water)
- Standards — use NIST-traceable reference thermometers
- Documentation — maintain calibration logs with dates, results, and technician signatures
