The EDL DBB Series combines hot and cold black body targets for checking compatible infrared thermometers and pyrometers.
The EDL DBB Series combines hot and cold black body targets in one instrument for checking compatible infrared thermometers and pyrometers. The two target ranges support calibration work across low and high temperatures without changing to a separate source.
Choose the DBB-350-DRL or DBB-650-DRL according to the highest temperature you need. Both models provide a cold-side range of −30°C to 110°C.
| Model | Cold-side range | Hot-side range |
|---|---|---|
| DBB-350-DRL | −30 to 110°C | Ambient to 350°C |
| DBB-650-DRL | −30 to 110°C | Ambient to 650°C |
| Parameter | Published specification |
|---|---|
| Target diameter | 50.8 mm (2 inches) |
| Emissivity | 0.98 ±0.02 |
| Stability | ±0.05°C |
| Accuracy | ±1°C; EDL also notes ±2°C depending on the environment. |
| Resolution | 0.1°C |
| Control sensors | RTD on the cold side; thermocouple on the hot side. |
| External reference provision | 0.125-inch (3.175 mm) reference sensor holes on both sides; reference sensors sold separately. |
| Weight | Approximately 9.07 kg |
| Power supply | 120 V AC, 10 A, 50/60 Hz; 240 V AC version available. |
Stability and display resolution are not the complete calibration uncertainty. Confirm performance at your required temperatures, with the intended reference system and operating environment.
The thermometer's measurement spot must fit within the usable target at the chosen distance. Check its optical specification, spectral range and emissivity setting before selecting the calibrator. A laser aiming mark alone does not establish the full measurement spot size.
Position the instrument consistently and allow the target to stabilise before recording readings. For traceable calibration work, use the applicable source calibration data and measurement procedure.
External reference sensors can be selected for the hot and cold sides with a suitable calibrated readout. Confirm the temperature rating and reference configuration when ordering. The optional BB-APP aperture supports assessment of spot-size and size-of-source effects.
The illustration is retained from the existing page. Use the current temperature ranges above and confirm the supplied configuration before ordering.

The Anritsu WE Series measures stationary surface temperature by resting the probe on the measurement target.
The Vaisala TMP1 is a robust temperature-only probe for demanding industrial processes, pharmaceutical applications and calibration laboratories.
The Anritsu BC Series measures internal temperature in food, liquids and semi-solid materials. Its needle design reaches the measurement point inside the sample.
The Sato Sigma II NSII-Q continuously records temperature and relative humidity on an easy-to-read paper chart, providing a visible record without requiring a computer or network.
The Sato 7610-20 is a traditional brass aneroid barometer with an integrated glass thermometer for local atmospheric-pressure and temperature observation.
The Vaisala HMD60 Series provides high-accuracy humidity and temperature measurement for demanding HVAC ducts and light-industrial applications.
The Sato SK-270WP is a waterproof handheld digital thermometer with interchangeable probes for food temperature checks, liquids and quality control.
Measuring range and waterproof protection depend on the probe selected. The S270WP-41 surface probe is not waterproof.
The Sato SK-L200TH II temperature and humidity data logger is discontinued. The replacement is the Sato SK-L754, selected with a compatible temperature and humidity probe.
The Vaisala HMP60 is a compact, durable and cost-effective humidity and temperature probe for equipment integration, data loggers, incubators, glove boxes, greenhouses and environmental monitoring systems.
It provides 0–100% RH and −40 °C to +60 °C measurement ranges, low power consumption, interchangeable Vaisala INTERCAP sensor and optional Modbus RTU communication.
Vaisala DL1000, DL1400, DL1016 and DL1416 temperature data loggers provide reliable, traceable monitoring for refrigerators, freezers, cold rooms, incubators and regulated facilities.
The Vaisala DL1700 is a four-channel thermocouple data logger for continuous monitoring and validation work at extreme temperatures.
The Sato Mini-Cube 7008-10 records temperature and relative humidity on a seven-day paper chart for routine inspection and filing.
