Baby & Personal Weighing Scales Lab Equipment Manufacturer, Supplier and Exporter in India

Fifteen scales are catalogued in the PWS series, PWS-0001 to PWS-0015: nine baby scales in pan, hanging and digital patterns, and six adult bathroom and platform scales from 120 to 200 kg. A weighing scale is specified as capacity by division, written for example as 20 kg by 10 g, and on a baby scale the division matters more than the capacity. Several of the figures published in this listing need checking before you order, and those are set out below.

Baby scales

Why the division decides a baby scale

Infant weight is monitored in grams. Daily weight change in a neonate, and weight gain against a growth chart, are both small numbers, so a coarse division hides exactly the change you are watching for. A 10 g division resolves that; a 50 g division does not. The capacity, by contrast, is rarely the constraint: a 20 kg scale covers infancy and well into toddlerhood.

So choose on the division first. For neonatal and growth monitoring, specify 10 g or finer. For community weighing where the question is roughly how heavy a child is, 50 g is adequate and the scale will be cheaper and more robust.

Published figures to check before ordering

Pan, hanging or rod

Adult scales

PWS-0010 to PWS-0015 cover bathroom scales at 120 and 150 kg and digital platform scales at 180 and 200 kg, with a second 200 kg type. For these, ask for the division (commonly 100 g on a digital platform scale), the platform dimensions, whether the display is integral or on a column, and the power arrangement, since a battery scale in daily clinic use needs an adapter. If the scale will be used with a height rod to calculate body mass index, ask whether a matching column and rod are available rather than buying them separately. PWS-0014 and PWS-0015 are both 200 kg with no stated difference, so ask what distinguishes them.

Calibration and verification

Ask three things of any scale here. Whether a tare function is provided, since a blanket, a nappy or a sling has to be zeroed out. Whether a calibration certificate is available and what the recalibration interval is; a scale whose readings go into a clinical record should be checkable. And whether the scale needs to be verified for legal metrology in your market, which applies in some countries to scales used in healthcare. Test weights to check a scale in service are listed under Laboratory Balances, where the guidance on weight classes also applies. Any accuracy figure quoted is confirmed in writing on the quotation; ask for its basis.

Further scales, an infantometer, a height and weight measuring machine and a baby scale with trousers are also listed among the 105 items under Medical Lab Equipments, so compare both listings before ordering. A stadiometer is under Medical Supplies. Laboratory and analytical balances, and calibration weight sets, are under Laboratory Balances. Neonatal equipment is under Infant Care. Parent range: Medical Apparatus.

State the capacity and the division you need, in that form, plus the pattern and whether a tare and a calibration certificate are required. For example a baby pan scale at 20 kg by 10 g with tare, or Digital Scale 200 Kg (PWS-0014) with the division and platform size confirmed.

Frequently asked questions

What division should a baby weighing scale have?

For neonatal care and growth monitoring, specify a division of 10 g or finer, because daily weight change in a neonate and weight gain against a growth chart are both small numbers. In this series PWS-0003 is listed at 20 kg, 10 g and PWS-0006 at 16 kg with 10 g graduations. For community weighing, a 50 g division such as the 10 kg by 50 g listed for PWS-0002 is adequate. PWS-0005, the digital baby scale, is listed at 20 kg, 20 g. Capacity is rarely the constraint: 20 kg covers infancy and well into toddlerhood.

Is a pan scale or a hanging scale better for weighing babies?

It depends where you weigh. A pan or tray scale is the clinic standard: the baby lies in a moulded tray that is comfortable and stable, and the tray sides stop a wriggling infant rolling. Ask for the tray dimensions and whether the tray is removable for cleaning. A hanging scale with a sling is light and needs no bench and no power, which makes it the choice for community and outreach weighing; confirm whether a sling or trousers are included and ask about spare slings. PWS-0008, a 5 kg hanging colour rod, is a simple field device - confirm what it comes with and its division.

Is the precision figure on a digital baby scale the same as its accuracy?

No. The listing for PWS-0005 gives Precision: 20 grams, but that figure describes the division - the smallest increment the display reads - not how close the reading is to the true weight. Division and accuracy are separate properties, and a scale can read in 20 g steps without being accurate to 20 g. When you ask for a quotation, request the division and the accuracy separately, and ask on what basis any accuracy figure is given. Both should then be confirmed in writing on the quotation rather than taken from the listing.

Which PWS codes have published figures that need checking before I order?

Several lines need a written answer first. PWS-0004 is published at 16 kg and 20 kg with a 0.50 gram division, which would be extraordinary for a mechanical baby scale of that capacity; the figure is most likely 50 g, so do not plan a growth-monitoring protocol around 0.5 g. PWS-0009 is titled as a 25 kg hanging scale, but its specification reads 0 to 99 cm with 1 mm graduations, which are height-rod figures. PWS-0007 has no stated capacity or division. PWS-0002 carries a third-party brand name in its title, so confirm who makes it and what is supplied.

What should I check before ordering an adult bathroom or platform scale?

PWS-0010 to PWS-0015 cover bathroom scales at 120 and 150 kg and digital platform scales at 180 and 200 kg. For any of them, ask for the division (commonly 100 g on a digital platform scale), the platform dimensions, whether the display is integral or mounted on a column, and the power arrangement, because a battery scale in daily clinic use needs an adapter. PWS-0014 and PWS-0015 are both 200 kg with no stated difference, so ask what distinguishes them. If the scale will be used with a height rod to calculate body mass index, ask whether a matching column and rod are available.

Do these scales come with a tare function and calibration paperwork?

Ask about both on every line before ordering. A tare function matters because a blanket, a nappy or a sling has to be zeroed out before the infant's weight is read. For calibration, ask what the recalibration interval is, since readings that go into a clinical record should be checkable, and whether your market requires scales used in healthcare to be verified. For a calibration certificate or any other paperwork, contact us for the latest copies of the relevant certificates. Test weights for checking a scale in service are listed separately under Laboratory Balances.

Key takeaways

• Division before capacity: specify 10 g or finer for neonatal and growth monitoring; 50 g is adequate for community weighing.
• Write it as capacity by division: for example a baby pan scale at 20 kg by 10 g with tare, plus the pattern you need.
• Pattern follows the setting: a pan or tray scale for the clinic, a hanging scale with sling for outreach, the PWS-0008 colour rod for simple field use.
• Precision is not accuracy: the 20 g on PWS-0005 is the readable increment, so ask for the accuracy and its basis separately.
• Confirm the flagged codes in writing: PWS-0002, PWS-0004, PWS-0007, PWS-0009 and the PWS-0014/PWS-0015 pair before quoting them.
• Adult scales need platform and power details: ask the division, platform size, display position and whether an adapter is supplied.

Listing defects noticed: PWS-0004 shows a 0.50 g division that is most likely 50 g; PWS-0009 is titled as a 25 kg hanging scale but carries height-rod figures (0 to 99 cm, 1 mm); PWS-0007 has no capacity or division stated; PWS-0001 covers two capacities under one code; PWS-0014 and PWS-0015 are both 200 kg with no stated difference; and further scales are also listed under Medical Lab Equipments, so the two listings may overlap.
