OMEGA CL355A-230 Compact Temperature Calibrator

The CL-355A is a small, lightweight, portable dry block calibrator, that offers fast heat-up and cooldown times with excellent performance specifications at a wide operating temperature range. It’ s a good choice for standard bench lab work or as a portable field unit. The unit covers the temperature range from 5° C ( 9º F) above ambient up to 400° C ( 752º 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. This calibrator is designed to work safely under the following conditions: ambient temperature range: 5 to 40° C ( 9 to 104° F) , up to 95% relative humidity, non-condensing. SPECIFICATIONS Minimum Temperature: 5° C ( 9° F) above ambient Maximum Temperature: 400° C ( 752° F) Cooling Rate, 400 to 100° C( 752 to 212º F) : 21 min Heating Rate, 20 to 400° C( 68 to 752º F) : 12 min Independent Over-Temperature Cutout: 450° C ( 842º F) approx.
