Models 2002B-J, -K and -T are low-cost 4 1/2 digit (±19,999 count) thermocouple meters with 0.1°C or 0.1°F resolution for indication-only applications. High accuracy is provided by five-segment linearization and matched, graded components for each T/C type.

Standard Features
Mechanical features include a bright 0.56 in (14.2 mm) display, a screw-terminal barrier strip for signal and power, and a compact 1/8 DIN case that requires less than 4.1 in (104 mm) behind the panel. Electrical features include cold-junction compensation, jumper selection of °C or °F, and a linearized recorder output of 1 mV per degree.

Options
Power options include isolated 9-32 Vdc and 26-56 V dc. A splash-proof lens cover which meets NEMA-4 requirements allows the 2002B to be used in harsh industrial environments.
