Which compact platform scale is the thinnest?

This article is based on an actual question asked by a potential customer*:

In the technical data of the Kern DE scale the dimensions are given as follows: 318 x 308 x 75 mm. I would like to know how high the scale is when it is standing on a straight surface, i.e. whether anything needs to be added to the 75 mm height.

Although I was not quite sure what the last sentence meant, I took the opportunity to confirm the height of the base of this scale. The Kern DE 60K10D I measured was around 77 mm high:

This is not much, but we sell an even thinner compact platform scale: The smallest scales in the Ohaus Catapult 5000 series are specified as 310 x 270 x 40 mm. The C51XE30R I measured was only around 42 to 43 mm thick:

While the base of the R-series Ohaus Catapult 5000 models is super slim, please note that the indicator is relatively bulky and that the stainless steel platform is not removable:

Another option would be the simpler Ohaus SD scales, which are also around 42 mm high (most compact models).

Thin scales can be advantageous if you plan to integrate them into a packing table (or other type of furniture), but keep in mind that they may not be as robust and serviceable as larger platform scales.

Differences to the previous Navigator scales

The NVL series (Navigator XL) with its unusual elongated shape is no longer available:

On all new scales, the upper side of the housing is now white, and the red display framing is more discreet. Another difference is the even higher contrast of the display:

The touchless IR sensor has been removed from all scales except the LFT models.

Interface options and accessories continue to be available

Numerous interface options are available, making these scales particularly interesting for data transfer to a computer: RS-232, USB device (virtual COM port) and Ethernet.

You can easily use the scales with the free Serial Port Data Collection (SPDC) software available from Ohaus as well as with our 232key keyboard wedge and Simple Data Logger software:

As standard, all scales are supplied with a plug-in power supply and can alternatively be operated with batteries. An optional lead battery is also available for the larger NVT models.

A carrying case is available to make the scales even more portable:
