Product Overview
Bimetallic indication thermistor (thermocouple) is an integrated temperature measuring instrument with on-site indication and remote display functions, which can be used to directly measure the temperature of gases, liquids, and substances. The instrument can clearly display the indicated values on site and also transmit signals remotely to the control room. The signals transmitted to the control room include Pt100 thermistor signals, K-type and E-type thermistor signals, as well as (4-20) mA standard signals that have been converted, serving as a dual-purpose meter.
