First of all, the shipment was 3 - 4 Weeks stated, actually Päkchen already was but after almost 2 weeks in mailbox! This consisted only of a plastic bag, thanks to the protective cover of the device seems but bring no disadvantage.
Next to process:
The Device:
While there are visible seams in the plastic on the side, this but you do not feel when using the device. The display is covered with a protective film, the buttons have a good attack, but not stiff. The cap of the electrodes can be removed without effort and sit on, but does not fall. The top cap of the batteries are used somewhat sluggish, but can be removed (on the back is a recess introduced dait you can grab the flat cap better) yet. If you look closely there, you can find on the inside markings that indicate how rum, the batteries must be eigelegt. Also on the back is a clip.
The Pocket:
It consists of sewn imitation leather. At the front of a small "window" of transparent plastic is sewn to close is a velcro closure. On the back is also a clip. It is simple, functional and does a pretty solid impression.
For instructions:
I was pretty excited because obviously more buyers so had their problems with the instructions. In my case, it consists of a double-sided printed piece of paper. One side is in Chinese, the other written in English. To the Chinese, I can not say much, except that it has a small additional figure, indicating the number and orientation of the batteries. The English instructions are in my opinion totally okay - it provides the necessary information for handling and maintenance of equipment and technical data. All this in perfect English (is not always the case ... I have quite a few instructions encountered was where apparently translated using the Google Translator). Because at some purchasers of the English part of the manual seemed to be missing or if someone with the English language is not familiar enough, here is the translation:
Operating Instructions:
1 .: Remove the protective cap.
2 .: Press the On / Off button once out of the water. The device will display 000.
3 .: immerse the device no more than 2 inches (about 5 cm, but in practice no deeper than the cap) into the water.
4 .: Wait until the display stabilizes. The unit will compensate for differences caused by the temperature automatically. Once the value does not change (10-30 seconds), press the Hold button to set the value out of the water to check.
5 .: Press again turn the On / Off button to turn the unit. If the device is not used, it switches off automatically after 10 minutes from.
6 .: shaking after using the water from the device or wipe it with a handkerchief.
Note: If the device indicates a flashing x10 symbol, multiply the value by 10.
Important: Do not completely drop the device into the water or immerse it deeper than the maximum 2 inches (5cm). The product is not waterproof. The device is not to be adapted for use in hot water.
Calibration Your meter has been calibrated at the factory to 500 s / cm, which is suitable for most applications. A re-calibration may be necessary from time to time, depending on the use.
Maintenance:
If the device can not be switched on or the display fades, replace the batteries. Please pay attention to the polarity (orientation) of the batteries.
If the pin electrode is dirty, clean it by washing in alcohol for 1 minute.
Do not touch or scratch the electrode.
Guarantee
This device is guaranteed to be free from defects in material and production for the period of 3 years after purchase. If within this period the repair or replacement of the device will become due and these are not hervorgerrufen by neglect or misuse, they may be returned to your dealer or our office and the repair is carried out kostenrei.
Accuracy: All I can (still) do not say anything. First measurements in tap water (371 s / cm) and deionized water (2 s / cm) seem consistent. If I find the time for it, I'll check the device with an appropriate calibration liquid.
Conclusion:
For the price the unit is in my opinion unbeatable. If it turns out gross measurement errors I will subsequently change the rating, but so far everything is top first. I use the tester to my Vollentsalzeranlage to check, so I know when to be regenerated. Furthermore, I also check the conductivity of the aquarium water (fresh water).
If someone is looking for a meter for a saltwater aquarium: power of this unit is not for use, but which can be seen also the product description - the measuring range 0-9990 s / cm is far too low for seawater.
