Standard/Base Metal Thermocouples
If your application involves harsh atmospheres or extreme temperatures beyond the range of our standard thermocouple line, please refer to our High Temperature Thermocouples page for more options.
ARi's standard thermocouple line is used in applications where high reliability is a priority. Our thermocouple line comes with the highest purity MgO insulation to yield maximum EMF stability and minimum drift problems caused by insulation impurities. We have thermocouples available in standard and special calibration limits for types K, J, E, and T per ASTM E-230. Upon request we can also custom manufacture all of our probes to meet your special requirements.
At Ari Industries, we manufacture many of our thermocouples using our own mineral insulated (MI) cable, use of this cable allows for bending of the sheath, and yields very long lengths of finished material. This enables us to supply most of our designs in any length or diameter you require. If you need assistance in choosing a product, our knowledgeable sales staff is always available to help.
