Electronic scales

HDWR offers electronic scales for retail, laboratory work, warehousing, logistics and production. The range covers everything from precision benchtop scales to industrial pallet and crane scales.

Scale types​

  • Retail scales — for weighing food and grocery items in shops. Capacity up to about 40 kg, stainless steel pan, fast load-cell sensor.
  • Laboratory scales — precision benchtop devices for pharmacies, laboratories and quality control. Accuracy down to 1/100 g.
  • Platform scales — heavy-duty low-profile floor scales for bulky and high-capacity items. Capacities from tens of kilograms to several tonnes; use a strain-gauge force transducer.
  • Pallet scales — specialised scales that typically replace the forks on a forklift or mount on a pallet jack. Weigh the load during normal handling — popular in warehouses and shipping.
  • Crane (hook) scales — suspended units with a steel hook. Used in manufacturing, transport and farming with cranes, overhead cranes and other lifting equipment. Operate on a tension-sensor principle.

Electronic scales FAQ

What are scales used for, what types are there and how do they work?
Scales are used to weigh products. The main types are: Retail scales — for weighing food and grocery items, capacity up to 40 kg, metal pan, load-cell sensor. Laboratory scales — precision devices for pharmacies and labs, accuracy of 1/100 g. Platform scales — for heavy and bulky items, strain-gauge force transducers. Pallet scales — used in warehouses and logistics, often mounted on a forklift. Crane (hook) scales — suspended units with a steel hook, used in production and transport, operate on a tension-sensor principle.
How does each type of scale actually work?
Crane (hook) scale: suspended from a sturdy steel sling, started with a dedicated button. When the display shows 0 it is ready (use TARE or ZERO if it shows a different value). The load hangs on a steel hook; a tensile-sensitive sensor produces the reading on the LCD display. Platform scale: products are placed on a metal platform; strain-gauge force transducers measure the pressure and stored algorithms convert it to a weight value in kg or lb on the display. Retail scale: items go on a metal tray placed over a measuring transducer. The transducer deforms under gravity, sends an electric signal, and the control module displays the value in kg or lb.
What is scale verification (legal-for-trade certification) and who needs it?
Verification is the process of confirming a scale's accuracy and compliance with metrological standards by a national weights and measures office (in Poland: Urząd Miar; in the EU governed by the NAWI Directive 2014/31/EU). It is mandatory for scales used in: trade (retail scales), pharmacy and medicine (laboratory scales), industry and logistics (warehouse, pallet and platform scales), customs and tax control. Scales used purely for internal company purposes or at home do not require verification.
How do I renew scale verification?
Initial verification (legalizacja pierwotna) is valid for 2 years from the date of manufacture. Re-verification (legalizacja wtórna) is valid for 25 months. Submit the scale to the national weights and measures office before the deadline expires. Re-verification is also required after moving the scale, damage to the verification plate, or repair. Operating a scale without valid verification can result in a fine and a ban on commercial use.
