Description:
100% brand new and high quality
This digital pen style meter is an ideal instrument for any aquarium， the fishing industry， swimming pools， school laboratories， food !#!amp!*! beverage， etc. And， this Digital TDS Water Quality Tester is ideal for all basic water testing applications. This product is highly efficient and accurate due to its advanced? microprocessor technology. Hold Function: stores measurements for convenient reading and recording. Auto-off function: the meter shuts off automatically after 10 minutes of non-use to conserve batteries. Measurement Ranges is between 0-9990 ppm， and from 0-999 ppm， the resolution is in increments of 1ppm; from 1000 to 9990 ppm， the resolution is in increments of 10ppm， indicated by a blinking 'x10' image.
Applied range: the production and drinking of purified water， Electroplating liquid， Boiler water， Water in fish tank， Water of swimming pools， Photograph flushing fluid， Well water， Deep phreatic water， Laboratory， Aquaculture， Food processing， etc

Zero: Adjust by the compensate potentiometer
Size(L*W*H): 15.6*3.0*2.0cm

?Note:

The value of TDS can show the content of impurities. The bigger of the value means that the content of impurities is larger; conversely， the content of impurities is small.

The factors that affect the test value of TDS: the temperature of water (the TDS-3 tester cannot test the water with high temperature such as， boiled water). The flow velocity of water (the TDS-3 tester cannot be applied to test the flowing water)
If the tester displays a flashing "X10" icon， multiply the reading by 10
Size for manual measurement， there may be a 0 to 2 cm error， belongs to the normal phenomenon.
And due to the difference between different monitors， the picture may not reflect the actual color of the item. Thank you!
