The new Ohaus Navigator series consists of a total of 18 scales (incl. 4 LFT models) with a maximum capacity from 220g up to 22kg and a readability starting at 0.01g. As usual in this segment, all scales use load cells with strain gages.

Note: Available models and characteristics may differ depending on your region. This article refers to scales available in Europe as of May 2019.
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.
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:
Directly using a smartphone as a scale is (still) impossible, while carrying a separate scale with you can be cumbersome. But what if the scale were integrated into the smartphone case?
The startup MyGrams currently wants to finance such a project on the crowdfunding platform Indiegogo. The scale is part of the protective case, can be easily removed and transfers the weight via Bluetooth to the MyGrams app. It can also communicate with other apps using an open API.
The scale is to have a height of only 6.5 mm. Unlike pocket scales currently available on the market, MyGrams uses four small load cells (one in each corner) instead of a larger load cell in the center.
A scale that is always with you and an easy-to-use app would be a great help for people who need to keep an eye on their diet. The compact size and Bluetooth connectivity could also make it a useful tool for many other applications.
I hope that MyGrams will be more successful than other crowdfunding campaigns for very compact scales with Bluetooth: iScale (Kickstarter) didn’t get financed while Weighitz (Kickstarter) hasn’t published any updates for over a year.
