The CL-355A is a small, lightweight, portable dry block calibrator, offering fast cool-down and warm-up times with excellent performance specifications over a wide operating temperature range. It is a good choice for laboratory work on standard benchtops or as a portable field unit.
The unit covers the temperature range from 5°C (9°F) above ambient to 400°C (752°F) using a large, multi-well machined aluminum insert block as the heat transfer medium to the sensors under test. The CL-355A uses the same aluminum inserts as the CL-740A calibrator. See the CL-700A series at omega.com/cl-700a for a listing of inserts.
This calibrator is designed to operate safely under the following conditions: ambient temperature range: 5 to 40°C (9 to 104°F), up to 95% relative humidity, non-condensing.
