DBCL400 Dry Block Temperature Calibrator
Introduction
The DBCL400 calibrator provides a safe, dry, constant temperature source for checking and calibrating a wide
range of temperature sensors, systems, indicators and thermometers. It is fast and economical and can be used
either on a bench top or as a portable field unit. The weight of the unit is only 11 pounds/5 kilograms. The unit
covers the temperature range from 5°C above ambient up to 450°C using a machined aluminum block as the
heat transfer medium. The temperature control circuit is built into the unit and includes over-temperature limit
protection.
Features include:
Even though the unit heats up rapidly, highly efficient insulation and an internal cooling fan ensures that the
case remains cool enough to handle even at maximum operating temperatures. The DBCL400 calibrator has
been designed to comply with all relevant electromagnetic interference and electrical safety regulations.

Note:
The above specifications are quoted for an ambient temperature range of 10°C/50°F to 30°C/86°F.
Outside this range, the quoted figures may deteriorate but the unit will still work safely.

Working environment

The calibrator units are designed to work safely under the following conditions:
Ambient temperature range: 5°C/9°F to 40°C/104°F
Humidity: Up to 95% relative humidity, non-condensing
• Maximum temperature of 450°C/850°F
