Additional Features

The OMEGA™ CL3512A handheld calibrator is two meters in one at an attractive low price. The CL3512A is a temperature calibrator, or thermocouple calibrator, that simulates type J/K/T/E thermocouple signals. Each signal is adjustable by using the coarse and fine dials. The CL3512A can also be used as a dual type J/K/T/E input thermocouple thermometer. Features include a large 3 1/2 digit display with backlighting and display selections of HOLD, °C/°F, and 0.1°/1°.

Thermocouple Type:
Temperature Range: Celsius or Fahrenheit User
Selectable Measurement Ranges: K-Type -200 to 1372°C (-328 to 1999°F), J-Type -210 to 1200°C (-346 to 1999°F), T-Type -200 to 400°C (-328 to 752°F), E-Type -220 to 1000°C (-364 to 1832°F)
Calibration Range: Same as measurement range Auto Range: 0.1° to 1° resolution above 199.9 (°C or °F)
Measurement Accuracy: Accuracy is specified for operating temperatures over the range of 18 to 28°C (64 to 82°F), for 1 year, not including thermocouple error. ±(0.1%rdg + 1°C) range -60 to 1372°C ±(0.1%rdg + 2°C) range -60 to -220°C ±(0.1%rdg + 2°F) range -76 to 1999°F ±(0.1%rdg + 4°F) range -76 to -364°F

Rated 5 out of 5 by from Nice calibrator for thermocouples This is the second one we bought and we are very happy with the performance. Two inputs and two outputs - for this price - can't go wrong.

Rated 5 out of 5 by from A ‘must have’ instrument Omega Thermocouple meter / simulator The ability to measure temperature with a thermocouple and to generate a simulated thermocouple voltage according to a selected temperature, is extremely valuable when debugging thermocouple applications. This model instrument does so at reasonable cost and with NIST traceable calibration certificate. PROs: 1. 0.1 degree Celsius display resolution up to 200 C. 2. Simulated TC output is variable with Coarse and Fine adjustment controls on the front panel. 3. Battery life is excellent. 4. Legendary Omega precision and reliability. CONs: 1. Simulator output range selections overlap. For example, 150C is selectable from 2 different simulator output ranges, both of which require the adjust pots to be near the end of their travel. This makes the adjustment more touchy for certain simulator output temperature settings. This is a very minor issue but a noteworthy characteristic. Overall this is a ‘must have’ instrument for anyone working with thermocouples in applications ranging from field installations to electronics development labs.

Rated 5 out of 5 by from Just what I was looking for! These little units are very easy to use. For output, the dial allows you to select ranges of output, then simply fine tune the setting with the small dials. Outputs are stable and do not wonder. It also reads T/C with easy, both J and K types. I'm using it as a development similar in my lab. I wish it had a digital interface (serial, USB, etc) to make it easier to collect data. But for the price, I can't complain!

Is a thermocouple included? If so, will it be able to measure temperatures down to -100 Celsius or will I need to by a more specialized probe?

Asked by: jbkidd
Thank you for your inquiry. Unfortunately this device comes with a thermocouple that cannot measure -100°C. We do not state an accuracy for SLE Wire-Made Products below 0°C (32°F). Accuracy testing shows it is no longer linear. If you want an accuracy for a SLE Product we suggest that you get a CAL-4 Calibration at an additional cost for temperatures below 0°C.

Does this unit come calibrated with NIST certificate? If not, how do I order that to cone ready to use?

Asked by: Tomj
Hi Tomj, Thank your for the inquiry. Yes, the CL3512A does include NIST certificate with 8 test points. Best regards OMEGA

Is that chargeable battery? or should be connected all the time?

Asked by: QCteam
This unit takes one standard 9-volt battery. It does not accept a charger to charge the battery while in the unit.
