OPTO 22 - ICTD-P3 _ Immersion ICTD Temperature Probe, 1/4-inch Diameter

Quick Specs:

Immersion ICTD Temperature Probe
1/4-inch Diameter

The ICTD-P3 is an immersion ICTD temperature probe, 1/4 inch in diameter. It is designed for use in liquid applications, for example thermowells within pipes. It can also be used to measure air temperature. The stainless-steel shell on this probe is isolated from the temperature element.
Use this probe with the following Opto 22 analog 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)

NOTE: Although the stainless-steel probe is liquid proof, it is possible that moisture could enter the probe via the connection between the wire and the probe. This connection should be protected from moisture, for example by using silicone.

Note: The ICTD-P2 immersion probe, 3/8 inch, is obsolete. Its specifications are shown in the specifications tab for reference.
