The concrete alkali content rapid measuring instrument is an apparatus for rapidly determining the alkali content of water-soluble substances such as concrete, sandstone, and admixture by ion selective electrode ISE method.
working principle
The ion content of water-soluble substances such as concrete, sandstone, and admixtures is quickly determined by ion selective electrode ISE method. Pre-treat concrete or other samples during use. The two pre-activated and calibrated electrodes were immersed in the mixed solution as indicated, one measuring the sodium ion content and the other measuring the potassium ion content. The instrument can be converted into Na2O and K2O content (%) by using the measured voltage data (mv), and the concrete alkali percentage Na2O (%) is automatically obtained after inputting the result into the calculation formula in the host. Each experiment took only 10 minutes after electrode activation.
Test procedure
Activation electrode
2. Weigh the sample and pretreat according to the instructions.
3. Calibrate the electrode and measure the sample to be tested
4. Display measurement data
Executive standard

testing object
Fresh concrete, wet concrete and concrete raw materials.
This is a popular ABS with PC luggage case, which is more durable than ABS only. The box surface material is abs with PC plate, not easy to peel and break. The wheel is 360 degrees universal single wheel design for rolling smoothly. The Tie rod still uses the solid aluminum alloy tie Rod. This plastic is unique as it is lighter than most aluminum luggage, is scratch resistant, and is less likely to crack during travel.
