A kirana or other small business in India needs a 10–30 kg tabletop weighing scale with two displays and a Legal Metrology stamp. Any scale used to sell goods by weight must be verified before use under section 24 of the Legal Metrology Act, 2009. Omace's shop scales start at ₹1,900 for 10 kg in 1 g steps and run about 2 days on a built-in battery (October 2026).
Why a shop scale must be verified and stamped
A scale that weighs goods for sale is a legal instrument in India. Section 24 of the Legal Metrology Act, 2009 requires every weight or measure used in a transaction to be verified before it is put to use. Section 33 of the same Act penalises anyone who uses an unverified weight or measure. Section 16 lets an unverified one used in trade be seized and forfeited unless it is verified and stamped in time.
The Department of Consumer Affairs says manufacturers and importers must get the government's model approval before they make or import a weighing instrument. State Legal Metrology officers then verify instruments periodically with standard weights.
Verification ends in a stamp and a certificate. The Delhi Legal Metrology department says its certificate records the date of verification, the next due date, the instrument's type and class, and its maximum permissible error. In Delhi, the manufacturer is responsible for getting a new instrument's initial stamping done.
Re-verification follows a fixed cycle. Assam's Legal Metrology department lists 24 months for weights, beam scales and counter machines. Every other weight or measure is re-verified every 12 months, so an electronic counter scale falls in the 12-month group. Your own certificate shows the exact due date.
Which scale suits which shop
Pick the scale by your heaviest single sale and the size of the goods. Omace lists all its counter models under weighing scale for shop, and each row below names one with its price including GST in October 2026.
| Shop | What you weigh | Scale to pick | Omace model and price |
|---|---|---|---|
| Kirana and grocery | Rice, dal, sugar and loose goods | 10 kg x 1 g or 20 kg x 2 g counter scale | Om-TT-ECO 10 kg kanta, ₹2,200 |
| Spices, dry fruit and sweets | Small amounts in grams | Compact 10 kg x 1 g scale | Om-TT-Micro Mini mini weighing machine, ₹1,900 |
| Sabzi and fruit | Crates and sacks up to 25 kg | 30 kg x 5 g scale with a 240 x 300 mm pan | Om-TT-Running SPD vegetable weighing machine, ₹3,100 |
| Chicken and poultry | Crates and bags | 60–300 kg platform with a chequered steel top | Om-CK-MS chicken weighing scale, ₹3,900–₹8,000 |
| Wholesale and mandi | Sacks, drums and pallets | 100–1000 kg platform kanta | Om-PS-MS, ₹6,000–₹29,999 |
| Jewellery | Gold and silver | 0.01 g jewellery scale | Ace JS-6002, ₹9,999 |
The 30 kg Om-TT-Running SPR costs ₹3,000 with the customer display on the back instead of a pole. The 20 kg Om-TT-ECO weighs in 2 g steps for the same ₹2,200 as the 10 kg model. The stainless steel Om-CK-SS poultry weighing scale costs the same as the mild steel Om-CK-MS at every size.
Features that matter at the counter
- A display for the customer. Every Om-TT scale shows the weight to the customer, on the back of the scale or on a pole, so both sides see the same number.
- Tare. Put the empty bag, tray or crate on the pan and press TARE. The display returns to 0, so packaging is never sold as goods.
- Battery backup. The Om-TT-ECO, Om-TT-Micro Mini and Om-TT-Running SPR keep weighing for about 2 days on a full charge of their built-in battery.
- Stainless steel pan. Food shops need a pan that wipes clean. The Om-TT-ECO and both 30 kg Om-TT-Running models have stainless steel pans, while the Micro Mini has a mild steel pan.
- Pan size. Pans run from 130 x 160 mm on the Micro Mini to 160 x 190 mm on the ECO. The Mini SPR and SPD have 175 x 225 mm pans, and the 30 kg Running models 240 x 300 mm.
- Overload sign and power saver. These models show an overload sign and have standby and auto power saver modes.
The Om-TT scales show weight only, so the price is worked out at the counter or in billing software. A billing scale with a printer and stored prices suits a supermarket that prints labels from the scale. Omace does not make a billing or price-computing scale yet.
How to choose capacity and step size
Choose a capacity above your heaviest single sale, then the finest step that capacity allows. Omace's 10 kg counter scales read in 1 g steps, the 20 kg Om-TT-ECO in 2 g steps and the 30 kg Om-TT-Running models in 5 g steps.
Every scale also has a smallest weight it should be used for. OIML R 76, the international standard for non-automatic weighing instruments, sets the minimum capacity of a class III scale at 20 verification intervals. Omace lists a smallest weight of 20 g for its 10 kg x 1 g Om-TT-ECO and Om-TT-Micro Mini. On the 30 kg models the Min is 100 g: the Om-TT series is a Legal Metrology approved model, and its approved 30 kg model is approved in accuracy class III with e = 5 g and Min 100 g.
The same standard sets how far a class III scale may read off. On initial verification it allows 0.5 interval up to 500 intervals, 1 interval up to 2,000 and 1.5 intervals above that, and twice these limits in service. A new 10 kg scale verified in 1 g intervals may therefore read ±0.5 g off up to 500 g and ±1 g up to 2 kg. Above 2 kg, the limit is ±1.5 g.
Keep the scale on a firm, level counter away from fans, and use it between 10 °C and 40 °C.
How to get your shop scale verified
- Buy an approved model. Ask the seller which Legal Metrology approved model the scale belongs to, and its accuracy class. Omace's Om-TT shop scales are an approved model in accuracy class III.
- Get it verified before first use. Apply to your state Legal Metrology office. In Delhi, the manufacturer arranges the initial stamping of a new instrument. Omace shop scales leave the Bagru factory already verified and stamped.
- Keep the bill and the certificate. The certificate shows the next due date. Jammu and Kashmir's Legal Metrology department asks for the purchase bill and the model approval certificate at a scale's first re-verification.
- Re-verify on time. Your state office or a Government Approved Test Centre can re-verify the scale. The Press Information Bureau reported in August 2026 that these centres may verify class III scales up to 150 kg and class IIII scales.
Heavier platform scales follow the same rules, explained in what makes a legal for trade weighing scale.
Why shops buy scales from Omace
