Answers to Your Questions

What – when – where –
how – why?

In this section we want to provide answers to recurring questions. This also means that the list of questions and answers will grow steadily.
For the near future we are planning to set up a forum for registered users where PrimeLab users can exchange their experiences and water knowledge – as it were, a first “water wiki”.

Please Note

Many answers for fixing errors are provided in the “Troubleshooting” section in the PrimeLab user manual and in the interest of brevity not reiterated here. The instruction manual can be downloaded in the section DOWNLOAD.

Can the PrimeLab really test ALL parameters?

The PrimeLab uses the JENCOLOR multispectral sensor and is thus able to measure all water parameters whose sample (typically 10 ml) will exhibit colour or turbidity after ad-dition of a reagent. That means that all visible colours, i.e. those in the spectral range from 380 nm to 780 nm, can be detected and evaluated by the sensor used in the PrimeLab.

However, first we as manufacturers must teach the PrimeLab which colour information (e.g. bright orange) is associated with which measurement (e.g. pH 7.21). To this end, we are constantly developing new reagents and parameters/test methods in order to fully exploit the advantages of the JENCOLOR sensor. 

Registered users are notified upon availability of a new parameter/measuring method. Via the “PrimeLab Desktop Assistant” software, a new method can then be installed after entering a (paid) code and enabled on the device – thus your PrimeLab will be never be obsolete!

Why are parameters/measuring methods missing on my PrimeLab?

When buying your PrimeLab you have chosen a certain number of parameters, or the retailer from whom you have purchased your PrimeLab has enabled some standard pa-rameters/measuring methods.

Via the “PrimeLab Desktop Assistant” software you can now enable new parame-ters/measuring methods on your PrimeLab after entering a (paid) code. This is very easi-ly done by clicking “Activate” and entering the unique 8-digit code.

If in the parameter list your desired parameter should not appear, this has not yet been developed by us. Write to us to find out whether the parameter you want is being devel-oped.

Do I have to buy a new PrimeLab when new parameters/measuring methods are availa-ble?

Definitely not! Your PrimeLab will not become obsolete – it may always be updated via the „PrimeLab Desktop Assistant” software. Once a new parameter/measuring method is available, registered users receive an email. The „PrimeLab Desktop Assistant” software likewise displays a notification when updates are available. By clicking “Enable” next to the desired parameter/measuring method in the parameter list and entering a (paid) code, even long after buying the PrimeLab still new parameters/measuring methods can be subsequently installed.

Does the PrimeLab provide more accurate data than other photometers?

With each measuring run the PrimeLab determines a plethora of information, as the JEN-COLOR sensor used measures not only at a single wavelength, but with only one light shot covers the entire visible spectrum.

Take for example the parameter “pH”, where the water sample may change its colour after addition of the detection reagent (phenol red) from yellow to orange and finally red. This colour spectrum already comprises 175 different wavelengths. Whereas conventional photometer technology uses only one single wavelength and even for this only the infor-mation “transmission” and “absorption”, the PrimeLab considers the complete spectrum and can thus accurately determine the water value. Without trade-offs and with a wealth of information that allows accurate evaluation of the measurement result.

In short: Yes, the PrimeLab detects water values more accurately than other, narrow-band photometers. How precisely the measurement result corresponds to the actual wa-ter value is mainly a question of how accurately and neatly the measurement was carried out, how good the reagents used are, and whether the user calibrates the PrimeLab regularly.

Why do readings on the same sample differ from one another?

Different results upon repeated measurement of the same sample of water can have quite different causes. As long as the differences are minor, can it be assumed that quite natural, indispensable reasons exist, such as:

Not every reagent tablet is 100 % identical with the others. The same applies to differ-ent-sized drops of liquid reagents or residues in powder packets at for powdery reagents. Thus mixing and pressing tolerances must be considered. Moreover, 10ml of a water sample in a measuring cylinder will not always be exactly 10ml, but once e.g. 10.02 ml, another time only 9.97 ml, etc., which will also have an effect on the measurement re-sult. Furthermore, reagent cuvettes are never totally identical in terms of density and bending, which affects transmission and absorption. Neither is every cuvette always in-serted completely identically into the device, but at least a little bit twisted. As wall thickness etc. are not consistently 100 % identical either, here, too, slight deviations and thus inter-measurement variations result.
Oxidizing reagents such as DPD in chlorine measurement do not cease to respond, but continue to react e.g. with oxygen in the air. However, there can be no guarantee that comparative measurements are always triggered at the same reaction time with millisec-ond precision. Slight soiling on the measuring glass (fingerprints, etc.) will also lead to different results. Air bubbles at the edge of the measurement glass will also interfere with the measurement.

Therefore there may be a number of reasons why test results are not 100 % identical. Only absolutely neat and accurate measuring minimizes errors.

How much data can I store in my PrimeLab?

Every measurement performed with the PrimeLab is assigned to a so-called “account”. This may be the address of a customer, one of many pools in a public bath, a project in a laboratory, etc. Only thus can measurement results be archived in a useful manner, and only thus can dosage recommendations be made with reference to the amount to be used (test base/account e.g. pool with 50 m³ of water content).

The PrimeLab allows storing 20 such accounts and 100 measurements associated with these accounts. In the software „PrimeLab Desktop Assistant” an infinite number of ac-counts and measurement results can be managed, and every time 20 new account data items can be stored on the PrimeLab. The PrimeLab is thus not restricted to 20 fixed ac-count data items. These can be changed as needed.

Measurement results are read from the PrimeLab and synchronized via Bluetooth by the software upon each wireless connection.

Does synchronization of measurement results require much effort?

The test results stored on the device are automatically synchronized after starting the software and selecting your PrimeLab. The software detects that there are new data and offers to synchronize them. One click is enough.

Can I store my own water treatment chemicals in the software for dosage recommenda-tions?

Definitely! The “PrimeLab Desktop Assistant” software allows you to define your own wa-ter treatment chemicals. For every parameter/measuring method activated on your PrimeLab, you can define any number of water treatment chemicals and specify how much of that change the parameters to which degree. It does not matter if your water treatment chemicals are liquids, tablets or granules.

From the information you provide, such as “5ml pH Minus change the pH of 1 litre of wa-ter by 0.08 pH” and the information about the ideal range, e.g. “7.2 – 7.4 pH”, and the information about the test basis (e.g. “50 m³ pool”) stored under the account on the ba-sis on the reading obtained a proposal will then be generated that can be printed.

Do I need to send in my PrimeLab for calibration?

Thanks to the JENCOLOR multispectral sensor, you must give your PrimeLab out of hand only if a truly major malfunction occurs, or when the life of the LED of your PrimeLab is drawing to a close.

As long as neither is the case, you can perform menu-driven calibration of the PrimeLab for yourself in less than 1 minute.
