OPTO 22 – ICTD _ Temperature Probe For ICTD Analog Input Modules
Quick Specs:
- Temperature Probe For ICTD Analog Input Modules
The ICTD temperature probe is used with ICTD analog input modules and is suited for air temperature measurement, for example in energy management, freezer control, and similar applications. Factory calibrated. Use this probe with the following Opto 22 input modules:
- GRV-IICTD-12 (12-channel groov EPIC module)
- SNAP-AICTD (2-channel SNAP module)
- SNAP-AICTD-4 (4-channel SNAP module)
- SNAP-AICTD-8 (8-channel SNAP module)
- G4AD4 (G4 module)
- AD4 (G1 Standard module)
The ICTD probe is for air temperature readings only (no liquids). If you need an immersion probe, see the ICTD-P3.
Note: The ICTD-P2 immersion probe, 3/8 inch, is obsolete. Its specifications are shown in the specifications tab for reference.
