IP00 vs IP37
Head-to-head comparison of two IEC 60529 ingress protection ratings.
IP00 and IP37 are both IEC 60529 ingress protection codes, but they differ in solid-object protection (level 0 vs 3) and liquid protection (level 0 vs 7). IP00 is rated for no protection and no protection, while IP37 provides > 2.5 mm — tool / wire and temporary immersion (up to 1 m).
IP00 offers no protection against solid objects or moisture. It is suitable only for indoor, climate-controlled environments where the equipment is fully enclosed within another protective housing.
Specified under IEC 60529, IP37 denotes protection against solid objects larger than 2.5 mm and protection against the effects of temporary immersion in water. Ingress of water in quantities causing harmful effects shall not be possible.. It is an IEC 60529 ingress protection code combining first-digit (solid) level 3 with second-digit (liquid) level 7.

IP37
Level 3 — > 2.5 mm — Tool / Wire
IP00 provides "No Protection" (level 0), while IP37 provides "> 2.5 mm — Tool / Wire" (level 3). IP37 is 3 levels higher.
Liquid protection
IP00
Level 0 — No Protection
IP37
Level 7 — Temporary Immersion (up to 1 m)
IP00 provides "No Protection" (level 0), while IP37 provides "Temporary Immersion (up to 1 m)" (level 7). IP37 is 7 levels higher.

Recommendation
IP37 offers higher overall protection than IP00. Choose IP37 for harsher environments; IP00 may suffice for milder conditions and can be more cost-effective.
