Clear turbidity standards are recognized by the primary stnadard for the calibration of turbidity meters online and in the laboratory for drinking water analysis.
Clear turbidity standards are traceable to NIST Primary Standards on account of their consistent particle size and photometric accuracy via UV-VIS spectroscopy.
Each lot is normalized to historical lots which were formulated to dilutions of 4000 NTU Formazin.

The kit contains all the parts required to assemble a functional lever shears. The graphic symbolises standard and production parts, and represents fixed and moving connections differently. All parts are precision-manufactured on CNC machines and feature standard engineering tolerances and surface finishes. The parts are clearly laid out on a base plate. They are grouped into individual assembly sequences. The base plate is covered with a transparent cover panel on which a graphical representation of the assembly structure is printed. Multiple trays are stackable, providing for space-saving storage. The surfaces of the finished parts have a gunmetal finish to prevent corrosion.

The mixers are equipped with a manually controlled discharge opening situated on the bottom part of the pan, for direct unloading of the mixture into a wheelbarrow or suitable container. Used to prepare concrete specimens or mixtures, these pan type mixers ensure a uniform efficient fast mixture action. The pan and the mixing gears have big thickness ratio, the gears are from hardened and rectified steel, and the motor reducer is in oil-bath with Gleason conical coupling. They are of easy and practical utilisation suitable for laboratory and field purposes. The mixing blades and paddle can be adjusted in height; they are manufactured from special quality hardened steel to resist wear.
