 Secchi Disk

WinLab

For determining the depth of visibility and light permeability of water. Sturdy design made of strong, hard-wearing plastic. Lead weight for better lowering. The approx. 15 cm high rod is fitted with an eyelet for fastening the lowering engine. The lowering line is marked in intervals of 100 cm with figures from 1 to 10 and in between additionally with line markings each 50 cm for better reading of the depth of visibility while the disk is being lowered....

 behrotest® flow-through unit, Aquabox

Behr

The Aquabox flow-through unit enables the correct, expert determination of on-site parameters during the collection of soil and sewage samples. The unit permits the simultaneous determination of electrolytic and physico-chemical parameters under optimal and reproducible flow conditions.

Aquabox is constructed of transparent, shock-resistant PETG, a thermoplastic copolyester. The transparent construction allows constant visual identification of problems during operation, e.g. sand or sediment contamination. All components which come into contact with water are made of non-wetting PETG (flow chamber and lid) or PP (inlet and outlet tubing). Therefore the water being sampled is not affected by any release of contaminants from the materials used for construction of the Aquabox. The lid is splashproof and easy to open and close by means of a quick-release fastener. The lid has 6 variable diameter, splashproof sensor holders for inserting sensors up to 25mm diameter (larger diameters available on request)....

 behrotest® waste water mixers

Behr

behrotest ® homogenisers. With transportable sample vessels. Homogenisers for pre-treatment, splitting and homogenization of heterogeneous water samples in accordance with the quality assurance and quality control standards for wastewater examinations. The vessels of the homogenizers are protected against damage in the yolk type frame and can be carried easily by the two handles. They can be filled at the sampling location by a flattened inlet connection. Capacities from 2 to 25 l permit extraction and collection of multiple samples. Exact measurement of the sample quantities due to graduation. Subsequently, the transport rack is just placed on the magnetic stirrer in the laboratory or in the sampling vehicle and the homogeniser is immediately ready for use. The speed of the magnetic stirrer can be adjusted by a controller. The user can thus comply with the specified cone height in all cases. Oxygen is thus prevented from entering the samples. Dosed extraction of the homogenised sample via PTFE spindle stopcock. 12V, with adapter for mains connection....

 Compact system for determination of volatile oils KOL

Behr

Complete and compact system for volatile oil determination according to DAB, with base unit, heating mantle, mounting frame and glassware....

 Continuous steam generator behrotest® WE 1/H

Behr

The injection of steam into the sample
guarantees a particularly gentle and uniform distillation. Steam is produced almost immediately (within maximum of 30seconds). The maximum period of steam injection depends only on the size of the external
container.
In WE 1 the distillation occurs only as a result of water vapour...
