general:
Your HI9813-5N is a quality product from Hanna Instruments.
This means that the instrument is tested before it leaves our production department by us.
It is a tool that should be. Treated with caution
While it is a 'eenvoudig'gebruiksmiddel in a rugged enclosure, but the techniques used are fairly complex.
When you take the meter for the first out of the package you will find the following:
- HI9813-5 (including pH / EC / temperature electrode HI1285-5).
- 3 packets of 20 ml calibration solution, ie pH 7 (HI70007P).
-EC 1.41 mS / cm (HI70031P) and 1500 ppm TDS (HI70442P)
- 2 packs of 20 ml cleaning fluid HI700661P
- 9 volt battery and manual.
Before using the meter for the first time, set the pH / EC / temperature electrode first place. Least 4 hours in the water (about 2 cm deep)
This is necessary to 'active' to the pH and prevents incorrect measurements.
