Supported Applications
The Omega DBCL-400 Ambient 5 °C to 450 °C Temperature Dry Block Calibrator provides a safe, dry, constant temperature source for checking and calibrating a wide range of temperature sensors, systems, indicators, and thermometers. Designed as both a benchtop unit and a portable field instrument weighing 11 lbs (5 Kg), the series utilizes a machined aluminum block as the heat transfer medium to establish stable thermal environments.
Operating Conditions & Performance
The DBCL-400 operates within an ambient temperature range of 5°C/9°F to 40°C/104°F and supports a measurement range from 5°C/9°F above ambient up to 450°C/850°F. An over-temperature limit protection circuit is set at 470°C/875°F. The unit features an automatic fan cooling system with the following thermal response characteristics:
- Heat up time (25°C to 400°C): 12 minutes
- Cool down (400°C to 100°C): 20 minutes
Accuracy specifications vary by temperature range: ±0.4°C (50 to 400°C) / ±0.7°F (122 to 752°F), and ±0.6°C (400 to 450°C) / ±1.0°C (752 to 850°F). Stability after 15 minutes is specified as ±0.050°C (50 to 400°C) / ±0.090°C (122 to 752°F). Well-to-well radial uniformity is documented at 0.015°C at 100°C and 0.052°C at 300°C. The display resolution is 0.1°. Quoted specifications apply for an ambient temperature range of 10°C/50°F to 30°C/86°F; performance may deteriorate outside this range while maintaining safe operation.
Configuration Options
The series supports two primary power supply configurations: 230V, 50/60Hz, 900W and 120V, 50/60Hz, 900W. Electrical connections utilize a power cable with plug; wire color codes are Live (Brown for 240V / Black for 120V), Neutral (Blue for 240V / White for 120V), and Earth ground (Green/yellow or Green). The unit requires earth grounding to ensure proper electrical safety.
Configuration options include various inserts, accessories, and replacement parts:
- Inserts: Multiwell insert with 1/8", 3/16", 1/4", 5/16" & 3/8" holes (DBCL-400-3041); Blank insert (DBCL-400-3047); Inserts configured for specific hole combinations including 5 x 1/4" (DBCL-400-3043), mixed sizes such as 1 x 9/16" & 1 x 1/4" (DBCL-400-3048), and Blackbody Source insert for IR pyrometers (DBCL-400-3129).
- Accessories: Unit carrying strap (4168), Insert extractor (4153), Carrying case (DBCL-3052), and region-specific power cables including UK 240V with 13amp plug (DBCL-UKCABLE) and Euro style R/A Schuko plug (4164).
- Replacement Parts: Heaters, temperature controllers, PRTs, solid state relays, fuses (4 amp for 240V units; 8 amp for 120V units), heater blocks, and cooling fans.
The unit dimensions are 8.75 x 8 x 8 inches / 222.25 x 203.2 x 203.2 mm (excluding carrying strap). Immersion depth is specified as 4.5" (114.3mm).
Key Product Differences
The DBCL-400 series distinguishes between two voltage variants: the DBCL-400-120 for 120V operation and the DBCL-400-240 for 230V/240V operation. Units marked 230V on the rating plate operate at 220V, while units marked 120V operate at 110V; in both cases where voltage deviates from nominal ratings, the heating rate degrades by approximately 8%. The series includes a fused plug for UK use fitted with a 5 AMP fuse. No operator-maintainable parts are located within the equipment.
