Washdown Bench Scale: IP Ratings, Stainless Builds and NTEP Models
A washdown bench scale has to survive a hose at the end of every shift, and our first pick is the A&D SJ-30KWP: 66 lb / 30 kg, IP67, NSF listed and NTEP legal for trade, on sale for $349.00 (regular $670.00) and in stock.
Short answer: choose a washdown bench scale by its IP rating, its materials and its capacity, and buy NTEP if you sell or charge by weight. For most food and portioning stations, the A&D SJ-30KWP is our pick at $349.00: IP67 waterproof and dust-tight, NSF listed, NTEP Class III, with a stainless pan and up to 5,000 hours on D batteries (not included). For a fully submersible IP68 portion scale, the Rice Lake RLP-30S (30 lb × 0.01 lb, NTEP) is $393.99. For cases on a wet floor, the Torrey EQB-50/100-W (100 lb, sealed tower display, NTEP) is $653.00. For a heavier stainless platform, the MNM Scales Optima OP-915SS-1616-300 (300 lb × 0.05 lb, NTEP) is $679.00. We are an authorized dealer for every brand we sell.
On sale: $349.00 (regular $670.00) on the A&D SJ-30KWP (#1160), in stock. Contact us or call (832) 290-3120 with questions.

Meat and poultry rooms, seafood counters, produce prep and chemical plants all clean with water, and a standard bench scale does not last long there. A washdown bench scale is sealed against water and dust and built from materials that stand up to sanitizers. This guide covers what the IP ratings mean, the materials to look for, how to size one, and a cleaning routine that keeps it reading true.

IP65 vs IP67 vs IP68
| Rating | Dust | Water | Typical use |
|---|---|---|---|
| IP65 | Dust-tight | Low-pressure water jets from any direction | Wipe-down and light spray areas |
| IP67 | Dust-tight | Temporary immersion (up to 1 m for 30 minutes under the standard test) | Hose-down meat, seafood and produce rooms |
| IP68 | Dust-tight | Continuous immersion beyond IP67, to conditions set by the maker | Scales that may sit in water or be soaked during cleaning |
An IP rating is not a pressure-washer rating. High-pressure, high-temperature spray can push water past seals that pass the immersion test, so use a low-pressure hose unless the maker says otherwise.
Materials that stand up to sanitizers
- Stainless steel pans and bases. Resist corrosion from water, brine and common food-plant sanitizers.
- Sealed displays and keypads. A hermetically sealed or IP-rated display keeps water out of the electronics.
- NSF listing for food zones. The SJ-30KWP is NSF 169 and NSF 14159-1 listed for food equipment.
- Removable pans. Lift-off pans, like the RLP-30S’s, let you clean under the pan where residue collects.
Sizing a washdown bench scale
- Capacity: the heaviest tub, tray or case plus its contents, with margin.
- Readability: 0.01 lb for portioning, 0.02 to 0.05 lb for cases and totes.
- Platform: larger than your biggest tray so nothing hangs off the edge.
- Power: battery models keep cords out of wet floors; AC models suit a fixed station.
- NTEP: required if you sell, buy or charge by weight. Every scale in this guide is NTEP; read what NTEP and legal for trade mean.
A hose-down routine that protects the scale
- Turn the scale off; unplug AC models and keep the adapter dry.
- Remove the pan if it lifts off and clean it separately.
- Rinse with low-pressure water, wash with your approved detergent or sanitizer, and rinse again.
- Do not aim spray directly at the display seals or cable glands.
- Let it drain and dry, refit the pan, level it, and check it with a known weight before the next shift.
Keep a cleaning and check log
- Date, shift and who cleaned it
- Sanitizer used
- Daily check weight and the reading
- Any damage to seals, cables or the pan
- Calibration due date
Calibration, repair and rentals
Washdown bench scales follow our capacity calibration tiers. The SJ-30KWP, RLP-30S and EQB-20/40-W are in the 6.2–35 kg tier: $250.00 in-house with a certificate or $595.00 NIST-traceable. The 100 lb and 300 lb models are in the 35–150 kg tier: $350.00 or $750.00. Mail-in calibration is available nationwide by mail, for in-house and NIST certificates, and usually takes 1–3 business days after we receive the scale. On-site calibration across Houston and its suburbs is $295 plus $2 per mile round trip. We repair all brands and types of scales, including washdown scales with water damage, through our Houston scale repair service, and we rent scales in the Houston area; call or get a quote.
Notes from our Cypress, TX shop
- Buy for the cleaning, not the weighing. If the room gets hosed down, start at IP67.
- Battery power keeps cords off a wet floor. The SJ-30KWP runs on D batteries; the Torrey -W models have rechargeable batteries.
- Check it after every deep clean. A known weight on the pan takes seconds and catches a problem before product ships.

Frequently asked questions
What is a washdown bench scale?
A bench scale sealed against water and dust and built from materials that handle sanitizers, so it can be hosed down with the room. The A&D SJ-30KWP (IP67, NSF, NTEP) is our pick at $349.00.
What IP rating do I need for a washdown scale?
IP65 handles low-pressure spray; IP67 handles hose-down rooms and temporary immersion; IP68 is for scales that may be soaked or submerged. Most food plants start at IP67.
Are these washdown bench scales NTEP legal for trade?
Yes. Every scale in this guide is NTEP, including the SJ-30KWP, the RLP-30S (CoC 10-068) and the Torrey EQB-W models (CC 98-206A2).
Can I pressure-wash a washdown scale?
Use a low-pressure hose unless the maker approves pressure washing. High-pressure, high-temperature spray can force water past seals, even on IP67 and IP68 scales.
What is the best stainless steel bench scale?
For hose-down rooms, the Torrey EQB-50/100-W has a food-grade stainless base and sealed display at $653.00. For a stainless station scale, our MNM Scales OP-915SS-1214-100 (100 lb × 0.02 lb, NTEP) is $399.00.
How much does it cost to calibrate a washdown bench scale?
Scales from 6.2 to 35 kg are $250.00 in-house or $595.00 NIST; 35 to 150 kg are $350.00 or $750.00. On-site in Houston is $295 plus $2 per mile round trip.
