BB703 Ambient +10°C to 400°C Temperature Blackbody Calibrator
Infrared Calibrator: Miniature Blackbody Calibration Source, Portable Design
Supported Applications
The Omega BB703 series is a portable, rugged, bench-top blackbody calibration source designed to test and calibrate infrared pyrometers. The unit features a built-in precision PID digital controller and includes a soft carrying case for field service or laboratory use.
Operating Conditions & Performance
The BB703 series provides a target plate temperature range of Ambient 10 to 400°C (Ambient 20 to 752°F). The internal control sensor is a Platinum RTD, Class A, 100Ω, alpha = 0.00385. Performance specifications include an accuracy of ±1.4°C (±2.5°F), a resolution of 0.1°, and stability of 0.3°C (±0.5°F). The target plate emissivity is 0.95.
Operating ambient conditions are limited to temperatures between 0 to 40°C (32 to 104°F) with humidity from 0 to 90% RH, non-condensing. A maximum setpoint reduction applies when operating at ambient temperatures in excess of 25°C (77°F). The unit is intended for indoor use only and includes a mechanical reset switch that opens the heater circuit during overheat conditions.

• Voltage Options:
• BB703: 115 Vac, 50/60 Hz
• BB703-230VAC: 230 Vac, 50/60 Hz
• Communications Option (-C2):
• RS-232 communications port with DB-9 connector
• Includes free CN9-SW Communications Software and a 1.8 m (6') cable
• Accessories:

Key Product Differences
The BB703 series distinguishes itself by voltage input and the inclusion of communications capabilities. The base model (BB703) operates on 115 Vac, while the -230VAC variant supports 230 Vac operation; both consume 175 W.
Models with the -C2 suffix add RS-232 connectivity and include the CN9-SW software package. The ordering structure follows the format BB703-[Voltage]-[Communications Option], such as BB703-C2 or BB703-230VAC-C2.
