BB-4A 100°C to 982°C Temperature Blackbody Calibrator
Infrared Calibrator: High Temperature Blackbody Calibration Source
Supported Applications
The Omega BB-4A series is a portable, rugged blackbody temperature reference source designed to test and calibrate non-contact infrared temperature instruments. Primary applications include the calibration of infrared pyrometers and transmitters with a spot size diameter less than 22 mm (0.88"). The unit features a built-in precision PID digital controller for stable operation as a high-temperature blackbody standard.
Operating Conditions & Performance
The BB-4A series operates within an ambient temperature range of 0 to 50°C (32 to 122°F) and supports humidity levels from 0 to 90% RH non-condensing. The device provides a measurement range of 100 to 982°C (212 to 1800°F). Performance specifications include an accuracy of ±1°C, ±0.25% rdg (±1.8°F ±0.25% rdg) and stability of ±0.15°C or less. The internal sensing element is a Type K thermocouple.
Warm-up time for the unit is 1.0 hr from ambient to 982°C (1800°F). Power requirements are 400 W, supplied via 115 Vac, 50/60 Hz or 230 Vac, 50/60 Hz depending on the model variant.
Configuration Options
The series is available in two voltage configurations to accommodate different regional power standards:
• BB-4A: High temperature blackbody, 115 Vac range 100 to 982°C (212 to 1800°F).
• BB-4A-230VAC: High temperature blackbody, 230 Vac range 100 to 982°C (212 to 1800°F).
The device includes a built-in Type K reference probe output and RS232 standard communication. Each unit is supplied with an NIST-Traceable Calibration Certificate including 3 data points.
Key Product Differences
Variants within the BB-4A series differ primarily by input voltage rating, which also affects physical weight:
• BB-4A (115 Vac): Weight is 8 kg (17 lb).
• BB-4A-230VAC (230 Vac): Weight is 15 kg (33 lb).
Both models share identical dimensions of 190 H x 410 W x 264 mm D (7.5 x 16.12 x 10.4"). The cavity opening is 22 mm (0.88") with an emissivity of 0.99 for all variants.
