New Products
Tamson TV4000AKV
Tamson ASTM D2440 Oxidation stability apparatus
Tamson is excited to announce the new TV4000AKV, replacing the TV2000AKV. The modular TV4000AKV EASY is a measuring system that includes everything you need to take precise and reproducible automated kinematic viscosity measurements. The TV4000AKV EASY is supplied with a single automated measuring channel. Filling and cleaning of the viscometer must be done manually. The AKV EASY is operated by a user-friendly touch screen and is capable of measuring the kinematic viscosity of samples that are suitable for Ubbelohde viscometers. This includes samples such as formulated oils, lubricants, diesel, hydraulic oils, additives, base oils, light fuels, waxes, crude oils and glycols. Eight different viscometers can be programmed in the system and up to 254 results are saved in the database and can be printed at any time. Each result consists of up to 99 runs. These runs can be done sequentially without interference from the user. The maximum time between two sequential runs is four hours. This allows the customer to test how the viscosity changes over time. The system determines the best repeatability from the measuring runs and supports calculation of the dynamic, relative and intrinsic viscosity. Optionally, the TV4000AKV EASY can be equipped with two measuring channels (dual channel). In the future, Tamson will introduce a single measuring channel equipped with a semi-automated cleaning module. The system will rinse the viscometer with the manually inserted cleaning solvent.

Tamson is manufacturing an ASTM D2440 Oxidation stability apparatus. The ASTM D2440 test method covers the oxidation stability of mineral insulating oils. The mineral transformer oils are placed together with the copper wire catalyst into the oil receptacle. The oil receptacle is heated in the bath at +110°C for 72 or 164 hours. During this time, oxygen is constantly bubbled through the sample. After this procedure, the oil is evaluated by measuring the amount of sludge and acids formed.

Tamson supplies an oxidation bath with six positions. The bath is standard supplied with six pieces of glassware and six flowmeters. The flowmeters have a fine adjustable needle valve, to ensure the correct amount of oxygen is supplied. A dryer tower is also supplied and is mounted on the side of the bath. The liquid bath is well insulated and all wetted parts are made from stainless steel to withstand high working temperatures. The stainless steel parts can easily be cleaned. Grommets around the openings can protect the glassware from scratches. The apparatus should be placed in a fume hood. In case this is not possible, six additional pieces of glassware can be used together with the standard supplied side brackets to prevent smell spreading into the laboratory.
