Temperature: transmitter, indicator, ON/OFF Regulator

Model Number
HD2717 / HD2817


Standard Lead Time

The instruments of the HD2717T… and HD2817T… series are transmitters, indicators, and ON/OFF regulators with data logging functions; they measure temperature and humidity.The models of the HD2817T… are fitted with a graphic 128 x 64 backlit display. The main feature of these instruments is their interchangeable probe.The probe can be replaced by the user without process interruption. Thus, the probe can be calibrated or repaired at a later time. The instrument is available in different versions: with horizontal probe (S.TO), vertical probe (S.TV) or with remote probe (S.TC), having the probe connected to the electronics by means of a cable of various lengths. The S.TO and S.TV probes are made of stainless steel AISI304, the S.TC probes can be of stainless steel AISI304 or Technopolymer PBT (plastic material).
