Additional Features

OMEGA's new CL1500 Series benchtop dry block probe calibrator is fast, accurate, and portable. It features a lightweight, rugged design suitable for both laboratory and field use. This hot/cold calibration source can accommodate probes of 6 different diameters and is available in either 115 or 230V versions. There are two different well styles available, standard and metric. The CL1500 Series uses a custom fabricated metal enclosure together with a high performance PID temperature controller to achieve a high level of quality, reliability and safety. The calibrator has a temperature calibration range of -5 to 125°C (23 to 257°F). Each CL1500 comes with power cord, complete operator's manual, RS232 cable (RS232 to USB converter cable also included), software and NIST traceable calibration certificate.The CL1500 software allows the user to control and monitor the temperature and performance of the calibrator in real time. The user is presented with 3 displays of the current temperature and setpoint, an analog dial, a digital display and also a graph with adjustable scale. It also allows fast and easy changes to be made to the setpoint through the use of 10 presets or using the course adjustment knob and fine tune buttons.

How many probes can it hold/calibrate at once? I have 11 thermocouples I was hoping to place into a dry block calibrator at once.

Asked by: Chem Eng1
Thank you for the inquiry. CL1500 has a 6 port calibration block. Sizes 3/8 down to 1/16 inch dia. Refer to figure 2 in manual. DBCL-400 block calibrator can be used with optional blank well. You can have the blank well drilled by 3rd party machine shop to match your probes. Please email TEMP@OMEGA.COM for more details. Best regards OMEGA

What is the optional blank well part number? I don't see it as an accessory or selectable option.

Asked by: Chem Eng 1
Thank you for the inquiry. The CL1500 does not have a removeable well. The DBCL-400 does offer removeable well. Best regards OMEGA
