Water quality trivalent iron tester/divalent iron tester, trivalent iron ion measurer
This instrument replaces the traditional visual colour method with the principle of optical electron chromatography. Anthropogenic errors were eliminated and the water samples were quickly visible when measured when they were placed in reagents. And then put this water in

Standard steel roller/50m certified steel roller (with amended value) sy-bg-50
The sy-series standard steel roller ruler product is primarily a working standard for the transfer of normal steel volume values. It uses stainless steel or high-quality carbon steel, usually for mass transfer or precision measurement, with fine step range and high precision, with condensed lasers (long range or no volume) and tics, small size, easy to carry, and is widely used for measuring measurements, bridges, large-scale oil and gas tanks, large-scale mechanical installations, standard swimming pools, and construction work on diving platforms. Quality has been well received by a wide range of users and has been used by various quality units。
The length of the standard roller can be determined。
