Our product advantages are as follws: | ||
Q: What areas and applications can it be used? | ||||||||
A: It can be used for qualitative or quantitative meansurements for water solution in the following areas: metallurgy, pharmacy, food, health, institutes, biological chemistry, life science, petrochemical industry, mining, quality control, environmental protection, etc. | ||||||||
Q: Does it need any installation | ||||||||
A: The installation is very simple, just need to connect it to power supply and turn it on, then you can use it. | ||||||||
Q: What standard accessories are included? | ||||||||
A: Main unit, 1cm cell holder(4 positions for single beam and 2 positions for double beam), 4 pcs of 1cm glass cuvette(all models) and 2 pcs of 1 cm quartz cuvette(UV models), one USB with user manual and power cable. | ||||||||
Q: Is PC software included? | ||||||||
A: The PC software(CFR 21 or regular one) is optional. Also the thermal printer is available on requested. | ||||||||
Q: Why the reading is red and reach its maximum value 3.00Abs? | ||||||||
A: Probably you use the glass cuvette in UV range. | ||||||||
Q: Why the wavelength calibration or self checking fail? | ||||||||
A: The deuterium lamp is turned off or there is something wrong with the D2 lamp, like the fuse, triode or the lamp itself. | ||||||||
Q: Why is the reading is not as accurate as before? | ||||||||
A: Do the wavelength calibration before testing or restore the device to its default factory settings. | ||||||||
Q: Why PC software can not be installed successfully? | ||||||||
A: Close your anti-virus software on the computer and do it again. | ||||||||
Q: Why the software can not be connected successfully? | ||||||||
A: Please return to its initial interface and don't enter any menu when connecting to PC software. And the device can not be operated once connected to software. Secondly, unload the previous/old version PC software if there is. | ||||||||
Q: Can the data transferred to USB or PC? | ||||||||
A: Yes, you can transfer the saved data on the device to a USB then copy it to PC, or you can save the data directly on the PC via software. | ||||||||
Q: Why the Abs value is negative(lower than zero). | ||||||||
A: Do the blanking or change the reference sample. | ||||||||
