Compact, Portable Temperature Calibrator Handheld or Benchtop Calibrator, Unit Weighs 4 kg (9 lb) CL-355A ߜ 10 Insert Formats Available ߜ 1 Multi-Well Insert Included (1⁄8, 3⁄16, 1⁄4, 5⁄16, 3⁄8") ߜ Maximum Operating Temperature of 400°C (752°F) ߜ Independent OverTemperature Cutout ߜ Temperature Sensor Burnout Protection ߜ NIST-Traceable Calibration Certificate Included ߜ Shoulder Carrying Strap, Mains Cable and Insert Removal Tool Included The CL-355A is a small, lightweight, portable dry block calibrator, that offers fast heat-up and cool-down 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 (9°F) above ambient up 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 CL-700A series on page K-36 for a list of inserts. 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.
