DR-H504 IPX7 & IPX8 Water Immersion Test Chamber
A stainless-steel pressure immersion chamber for evaluating enclosure resistance under specified water depth or equivalent hydrostatic pressure.
Use the Correct Configuration for the Claimed IP Rating
Do not mix the two products: the original marketing copy describes 500–5000 L open lifting tanks, but the Technical Parameters tab describes this DR-H504 pressure vessel. This page now follows the actual DR-H504 technical table.
Verified DR-H504 Technical Parameters
| Parameter | Published value | Procurement note |
|---|---|---|
| Internal dimensions | Diameter 1000 × height 1000 mm | Confirm usable basket dimensions, specimen displacement and lid clearance. |
| Chamber material | SUS304 stainless steel, stated thickness 2 mm | Final pressure-vessel construction and design verification must be confirmed in the approved drawing. |
| Water-depth simulation | Up to 50 m using compressed-air pressure | Equivalent depth depends on controlled gauge pressure; define the required pressure explicitly. |
| Water pressure | Ambient to 0.5 MPa | Published pressure-gauge accuracy is “0.25 degree”; clarify whether this means accuracy class 0.25. |
| Timer | 0–99 min, 99 s | Confirm resolution and whether pressure ramp/stabilization time is separate from exposure time. |
| Sample handling | Portable stainless-steel basket | No powered lifting system is stated in the technical table. |
| Water-level indication | Scaled water pipe | Confirm calibration and readable range. |
| Pressure safety | Pressure protection, anti-explosion device, drain and pressure-release device | Request interlock logic, relief setpoint and inspection documentation. |
| Electrical safety | Overload, short-circuit, grounding protection and alarm display | Confirm supply, rated power and destination-country protection. |
What Was Removed From the Former Content
- Unverified 500–5000 L tank range, 0.3–1.5 m depth and electric-hoist specifications.
- Invented product-recall cost figures and public equipment price ranges.
- Unsupported ISO 17025, IATF 16949, ISO 13485 and 21 CFR Part 11 compliance claims.
- Universal IPX8 claims such as “3 m for 30 minutes”; IPX8 conditions are product-specific.
- Statements that every IPX7 specimen uses exactly the same one-metre placement rule.
- Open-tank maintenance instructions that do not describe this pressure configuration.

Pressure-Chamber Safety Review
A 0.5 MPa water-pressure system stores significant energy. The quotation and installation review should identify vessel design basis, locking and pressure interlocks, relief protection, calibrated pressure measurement, controlled venting, emergency stop, inspection access and operator training. The lid must not open while pressure remains in the vessel.
Engineering confirmation required: the source page does not provide vessel-code certification, design pressure, proof-test pressure, relief setpoint or inspection record. These must be confirmed for the destination and intended use.
Standards Context
IEC 60529 classifies degrees of protection provided by electrical enclosures. Equipment capability alone does not certify the product: specimen preparation, immersion/pressure condition, duration and acceptance evaluation must follow the exact applicable procedure. IPX7/IPX8 also do not prove resistance to water jets such as IPX5, IPX6 or IPX9.
For spray testing, see the IPX3/IPX4 rain spray chamber. For hot high-pressure jets, see the IPX9K test chamber.
Frequently Asked Questions
Is DR-H504 an open immersion tank?
The verified technical table describes a sealed pressure immersion chamber with a portable basket, not the 500–5000 L lifting-tank range described in the former marketing copy.
What is the maximum published pressure?
The current technical table states ambient pressure to 0.5 MPa, described as equivalent to approximately 50 m water depth.
Does IPX8 always mean 3 m for 30 minutes?
No. IPX8 conditions are agreed for the product and must be stated explicitly.
Can this chamber perform IPX7?
Potentially, provided the fixture, water placement and procedure reproduce the applicable IPX7 requirements. Confirm the method in the approved configuration.
Can the specimen operate during testing?
Only with appropriately engineered electrical/signal feedthroughs and an approved electrical safety plan.
What does pressure-gauge “0.25 degree” mean?
The source wording is unclear. Confirm whether it means accuracy class 0.25 and request the calibrated range/certificate.
What information is needed for selection?
Provide specimen drawing and mass, IP rating/method, target depth or pressure, duration, cycles, water temperature, operating state and acceptance criteria.
Does the chamber itself certify an IP rating?
No. It supplies test conditions; certification or conformity depends on the complete test, records and authorized evaluation process.
Specify Pressure, Duration and Specimen Size
Send the enclosure drawing and exact IPX7/IPX8 condition so DERUI can confirm basket fit, pressure control, feedthroughs and safety configuration.
