This unit
The CT7110 is a microprocessor-based 2-pen circular chart recorder that measures, displays, records, and controls up to two process variables simultaneously. This instrument accepts universal inputs across millivolts, volts, milliamps, thermocouples (J, K, T, E, N, R, S, B, C types), and RTDs, making it suitable for diverse industrial monitoring applications. The 250 mm circular chart pairs with dual 4-digit LED displays offering user-configurable resolution and integrated filtering.
