30 Series Operation Manual
Media Compatibility (LP and HP)
Liquids and gases compatible with PTFE (Polytetrafluoroethylene) penetrated, hard anodized aluminum (transducer housing), 316 stainless steel (sensor), and
Viton
®
(O-ring). (Viton is a registered trademark of Dupont Dow Elastomers.)
Products with the letters “SPSS” in the suffix of the part number (e.g., “IS33-36/3000-SPSS”), have stainless steel manifolds and therefore the only wetted mate-
rials are stainless steel and Viton.

Note:
When connecting to circuits that included HART transmitters, a 250 ohm resistor must be placed in series with the calibrator, to prevent damage to the
calibrator and any other equipment connected to the loop. mA can be displayed as a percentage, where 0 to 100% corresponds to either 4 to 20 mA or
10 to 50 mA.
