Frequently Asked Questions
On the current N-LF2000 models, this means that the conductivity value is above the upper limit of the measurement range. To be more precise: for conductivity values above 2050 µS/cm, the display shows “EEEE µS/cm”, which means that the measurement range has been exceeded.

Frequently asked questions
Where can I find the safety data sheet for the solution I want to use?
The safety data sheet is included in printed form with the delivery of the goods. The safety data sheet can be viewed or downloaded at any time in the download area of the online shop.
What bottle sizes are available?
Generally, there are 60/70 ml, 250 ml, 500 ml and 1,000 ml bottles. There is one exception, for example, with brands such as Hanna, where bags are sold instead of bottles.
How long do the solutions last?
The shelf life is printed on the product label. Upon delivery, the shelf life is at least 7 months.
Can the solutions still be used after the expiry date?
No, because the function and quality can no longer be guaranteed after the best-before date has expired.
How can I dispose of the solutions?
Please refer to the safety data sheet for more detailed information on the disposal of the solutions. Disposal must be carried out in accordance with official regulations.
What is the emergency number for acute poisoning?
The emergency number for the North Poison Information Centre is +49 551-19240 and is available 24/7.
