The Aquacounter/Hiranuma MOIVO-A19 is manufactured in Japan , replaces the Aquacounter AQV-2200 series and has the following features:

・ 8.4 inch color LCD touch panel ・ 16 steps of angle adjustment of the liquid crystal display ・ Audio guide ・ Various LED displays ・ Manual reagent supply / discharge pump In addition, we have incorporated popular functions such as data management with USB memory, built-in thermal printer, simultaneous measurement of up to 4 types of moisture and titration!

Three optional autosampler choices are available-see pics below

Product features

1. Large color touch panel LCD

Largest 8.4 inch screen in its class.
It is easy to input characters on the touch panel, and each operation can be performed intuitively from the menu screen.
A protective film that can be replaced to prevent scratches and stains.

2. 16 levels of angle adjustment for liquid crystal display

We provide the best experience for each user.
Since the angle is locked, it will not fall down even if you push it.

3. Audio guide

Audio notifies you of the end of measurement, errors, and reception from the balance.
This makes it easier to check even from a distance.

4. Simultaneous measurement of up to 4 types

By adding a titration station, it is possible to simultaneously measure up to four types of moisture measurement and titration.

5. Built-in thermal printer

Equipped with a thermal printer with a paper width of 58 mm.
It can be set easily by inserting the roll paper and closing the cover.
The information you want to know is clear at a glance with Japanese printing.

6.USB/LAN connector

About 9,900 data can be saved in the USB memory.
With optional software, you can view results on a PC and use the "recalc" function.
You can also browse with a web browser using LAN.

7. User authority setting function

You can limit the users who can use it, which improves security
and prevents unintended changes in measurement conditions.

・Administration authority settings; Individual password settings

8. Status display by 3-color LED

You can check the operating status from a remote location.
You can immediately notice sudden troubles.

9. Easy replacement of burette head

To remove, simply pull forward.
Reagent bottles can be replaced with one hand.

10. Economy purge function

Repeat discharge and suction at the upper end of the syringe.
Reagent replacement work can be automated, and waste liquid can be greatly reduced.
The number of economy purges can be set from 1 to 99 times.

11. Reagent back-up function

Don't waste expensive Karl Fischer reagents.

12. Rotation speed can be set in 40 steps

The manually set speed is
easy to see and understand with the bar display of 10 LEDs. (4 steps per scale)

13. 2-color LED display for operating status

You can check the operating status from a remote location.

14. Manual feeding/discharging unit

A manual pump can be used to supply and dispense reagents.

*The titration cell is also configured with a drain cock.
In that case, the manual feeding/discharging unit is not included.

  • The image is an example of coulometric method

15. Small volume titration cell with low running cost

・The amount of titration solvent used is 2/3 of the conventional amount. Reagent-saving also
leads to reduction of waste liquid and running cost.
・Since the surface area and volume in the cell are small, blanking before the start of measurement
is quick.
