Newport 202A-JF1 Thermocouple Meter -216F To +1400F 115Vac ~NEW~

Description

Newport 202A-JF1 Thermocouple Meter -216F To +1400F 115Vac ~NEW~.
Models 202A-J
,
-K
and
-T
are 3 1/2 digit ±1,999 count) panel meters for thermocouple types J, K and T. They are available for display in °C or °F and resolution of 1° up to 1,999° or 0.1° up to 199.9°. They are recommended for demanding indication-only applications where exceptionally low-cost is required. For display up to 1,999.9° with 0.1° resolution, Newport recommends its 2002B Series meters, which provides a 4 1/2 digit (±19,999 count) main assembly.
