The Arklay S. Richards Co., Inc. always stocks a wide variety of thermocouple wire, which covers a service temperature range from -123 to 1093"C (-190 to 2000'F). This enables you to select the most suitable and economical wire for your application. The maximum service temperature is based on the lower limit of the wire gauge, or insulation characteristics. Refer to the two charts below. All Richards thermocouple wires are carefully selected and matched to conform to ANSI MC 96.1 standards. The testing for accu- racy and color coding is completed here in own own laboratories. Refer to our limits of error table in this catalog. Special premium grade wire is available upon request. Premium grade thermocouple wire can be designated by adding a double type letter to the cat- alog number. An example of a catalog number for premium grade thermocouple wire would be 2OKK'HG.
