Wet market and seafood stall owners hose down their weighing area daily — sometimes several times a shift. Most weighing scales aren't built for that. A scale marketed as "waterproof" on a supplier's website can mean anything from "survives a splash" to "can sit under running water all day," and the gap between those two claims is exactly where market traders end up with a corroded, unreliable scale six months after buying it. Here's how to tell the difference before you buy, and what actually matters for a wet market, seafood, or poultry stall in Malaysia.

Why "Waterproof" Isn't One Thing

The number that actually matters is the IP (Ingress Protection) rating — a two-digit code that states exactly what a scale is built to survive. The first digit covers dust, the second covers water. For wet market use, the second digit is what counts:

• IP65 — protected against low-pressure water jets from any direction. Fine for occasional splashing or a light rinse, but not built for standing water or a full hose-down.
• IP67 — can survive temporary submersion (typically up to 1 metre for 30 minutes). Handles heavier washdowns.
• IP68 — rated for continuous or deeper submersion. This is the tier built for a stall that gets properly hosed down every single day, including under and around the platform.

Scales described only as "wet-product friendly," "splash-proof," or "washable" without a stated IP number usually aren't independently rated at all — the platform is just sealed plastic or coated metal that tolerates occasional moisture. That's a real and useful category for a dry-adjacent counter, but it's not the same product as an IP68 stainless steel platform scale, and treating it that way is how scales fail early.

What a Wet Market or Seafood Stall Actually Needs

The daily reality of a wet market stall is harsher than most "commercial" scales are designed for: standing water on the floor, ice melt, fish scales and blood, brine, and a daily hose-down of the whole stall including the scale itself. For this environment:

• IP68 rating, not just a stainless finish. A stainless steel platform looks corrosion-resistant, but if the internal load cell and connectors aren't sealed to IP68, water still gets in over time — usually showing up first as drifting or unstable readings.
• Stainless steel platform and housing — resists pitting from salt and brine far better than painted steel, which will rust at the seams within months in this environment.
• Simple, sealed keypad — fewer moving parts and seams for water to find a way in.
• Rechargeable battery operation — useful where mains power near a wet floor is a safety concern, and common on stall-format scales.

The Seko BS-SK-P Series, for example, carries an IP68 rating with a stainless steel platform in 60kg and 150kg capacities — sized for a typical seafood or poultry stall rather than an industrial production line.

Poultry and Seafood: A Few Extra Practical Notes

Beyond the IP rating itself, a couple of things matter specifically for live/fresh poultry and seafood trading:

• Platform size and stability — a platform that's too small for a full basket or tub of fish forces awkward, off-centre loading, which affects both accuracy and the load cell's long-term health.
• Fast display response — for a busy stall weighing dozens of transactions an hour, a scale that settles quickly matters as much as the IP rating for keeping queues moving.
• Corrosion isn't just cosmetic — a rusted hinge or connector on a scale used for trade can eventually affect the reading itself, which is a compliance issue, not just an appearance one.

Compliance: What Malaysian Wet Market Traders Should Know

Any scale used to determine the price a customer pays — which covers essentially every wet market, seafood, and poultry stall — falls under the Weights and Measures Act 1972 and needs to be verified/type-approved, not just accurate by eye. The Ministry of Domestic Trade and Cost of Living (KPDN) is the enforcement body for this, and its officers do carry out on-the-ground checks at wet markets and trading premises, including recent joint operations at markets and landing points that specifically inspected traders' scales. Traders who bring their instruments for verification voluntarily are generally viewed far more favourably than those found using an unverified scale during a spot check.

This is separate from — but related to — the IP rating question. A scale can be perfectly accurate and still fail a durability check if water ingress has affected the mechanism over time, which is one more reason the correct IP rating matters for trade use, not just for the scale's lifespan.

Budget Tiers: Matching Protection Level to Your Stall

Not every stall needs the same tier of protection, and there's no need to overpay for IP68 if your setup genuinely doesn't need it:

• Dry-adjacent counter, occasional splashing — a sealed plastic-body pricing scale (no formal IP rating, but marketed for wet-product handling) is a reasonable, lower-cost fit. The Camry JC81W is an example — a plastic body and tray built to tolerate wet product handling, without the stainless steel and IP68 rating of a full washdown scale.
• Daily washdown, standing water on the floor — this is where an IP68 stainless platform scale like the Seko BS-SK-P earns its price difference; a lower-rated scale in this environment will likely need repair or replacement well before an IP68 unit does.
• Larger operations needing indicator flexibility — for setups building a custom platform or integrating with existing equipment, a standalone IP68-rated indicator such as the Excell GW Waterproof Series indicator (available via ewcmalaysia.com.my) pairs with a separate load cell/platform setup.
• Verified/type-approved requirement for trade — models built to OIML Class III, such as the Mettler Toledo BBA236, are the right starting point if formal verification is a requirement for your operation.

Frequently Asked Questions

Q: Can I just hose down any stainless steel scale?
A: Not safely, unless it carries an IP65 or higher rating specifically. Stainless steel resists surface corrosion, but the platform, load cell, and connector seals are what actually determine whether water can get inside — a stainless finish alone doesn't guarantee that.

Q: What's the difference between IP65 and IP68 in practice for a wet market stall?
A: IP65 tolerates a splash or light rinse from any direction. IP68 is built for standing water and a full daily hose-down, including underneath the platform. If your stall floor genuinely gets wet and hosed daily, IP68 is the safer long-term choice even at a higher upfront cost.

Q: Does a waterproof scale still need to be verified for trade use?
A: Yes — IP rating and trade verification are separate things. A scale can be fully waterproof and still need verification/type-approval under the Weights and Measures Act 1972 if it's used to determine what a customer pays.

Q: My scale isn't IP-rated but I've been hosing it down anyway — is that a problem?
A: It's the most common cause of early failure we see reported for stall scales — water tracking into unsealed seams and gradually corroding the load cell or connectors, which shows up first as drifting or unstable readings rather than a sudden failure.

Q: Does V&C Infinity help with calibration for scales used at wet markets?
A: Yes — V&C Infinity Enterprise Sdn Bhd is a licensed weighing scale repairer in Malaysia, qualified to apply for trade metrology licensing, and can arrange ISO 17025-certified calibration for customers.

Get the Right Fit for Your Stall

Buying more waterproofing than you need wastes money; buying less than you need means an early replacement.
