New 2019 Ohaus Navigator scales

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.

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:

Ohaus Navigator (NV), Navigator XL (NVL) and Navigator XT (NVT) scales – what’s the difference?

Physical dimensions

While all scales in the Ohaus Navigator product range are fairly compact, their dimensions vary according to the series to which they belong. In our photo, you’ll see the Navigator XT (NVT) on the left, the narrow and lengthy Navigator XL (NVL) in the middle and the smaller Navigator (NV) on the right:

The Navigator (NV) is the only one with different platform shapes within the series: The NV212 – the only scale with 0,01g readability in the entire range – has a round platform as shown in the picture while higher capacity scales have a platform which is similar to the other series.

Dimensions (width x length x height in mm)

Navigator XT (NVT): 240 x 249.5 x 69.8
Navigator XL (NVL): 204 x 282 x 74
Navigator (NV): 204 x 212 x 58

Options

All scales can use the same interface options (RS-232, USB or Ethernet) as they have the same option slot on the bottom. The photo provided by Ohaus shows the Navigator XL (NVL) with installed USB interface:

However, only the Navigator XL (NVL) and XT (NVT) series have room for an optional rechargeable battery:

The scales can also be used with non-rechargeable batteries (4 size AA batteries for the NV and 4 sice C batteries for the NVL and NVT).

Performance

All scales stabilize quickly (within one second according to Ohaus) and perform similarly:

NVT16000 2 d ± 2 d ± 3 d

The values are expressed in scale intervals (d, difference between two successive indications, often also referred to as “(display) division” or “readability”). OCL stands for off center load. To minimize the OCL error, place the weight in the center of the platform. Approved models are not included in the table as their availability varies by region.
