HZYN-1301 ASTM D445 Tsis Siv Neeg Roj Kinematic Viscometer

HZYN-1301 Kinematic Viscosity Bath Astm D445 Roj Kinematic Viscometer

Cov ntsiab lus

This Kinematic Viscometer is designed and manufactured specially according to the national standard "GB265 – 88 Determination of kinematic viscosity of petroleum products" . It's suitable to determine kinematic viscosity of liquid petroleum products. This apparatus has the function of timing of the trial sample movement and can calculate the final result of kinematic viscosity. This method is suitable to determine kinematic viscosity of liquid petroleum products ( It refers to Newtonian liquids ), and its unit is m2/s. Generally in actual utilization, the unit is mm2/s. The dynamic viscosity is equal with the result which use kinematic viscosity to multiply the density of the liquid. By this method, it can determine the time that the liquid with the certain volume flows past the calibrated glass capillary viscometer under the gravity in the certain stable temperature and the value that the constant value of capillary in the viscometer multiplies the flowing time, that is , the determined kinematic viscosity of liquid at the temperature. At the temperature, the value that kinematic viscosity multiplies the density of the liquid in the same temperature is the dynamic viscosity at the temperature.

Kev siv cov xwm txheej

(1) Environmental kub: 0 degree -40 degree

(2) txheeb ze humidity:<>

Nco ntsoov

(1). Thaum tsis muaj dej hauv lub thoob dej yug ntses, nws txwv tsis pub siv hluav taws xob.

(2). In the liquid of the bathtub, there can't be impurities and floating materials in order to avoid to block the test holes. For the new bath liquid , it often appears bubbles when heating, which will affect the test, especially when it appears bubbles in the test holes, it will have the most serious affect. Please loose the capillary to check if there is bubble in the test holes. If it appears, please use the hose to blow in order to get rid of the bubbles or use the clean the toothbrush to wash off the bubbles.

(3). Ua ntej peb siv lub cuab yeej, peb yuav tsum xyuas kom meej lub ntiaj teb txhim khu kev qha.

(4). Thaum peb rov- pib lub cuab yeej, lub sijhawm siv yuav tsum siab dua 15 feeb. Thiab cov cuab yeej tau pib hauv lub xeev da dej txias, thiab nws yuav tsum tau siv tom qab 45 feeb.

(5). When we rectify the temperature with the full-immersion thermometer, the effective scale of the thermometer can't be exposed to the liquid level of the constant temperature bath.

(6). Txwv tsis pub khaws lossis siv cov cuab yeej hauv qhov chaw ntub dej nrog cov roj corrosive.

(7). Thaum peb kaw lub capillary, thov nco ntsoov qhov siab ntawm qhov qhib sab saud thiab zam kom tsis txhob nkag mus rau hauv dej hauv lub raj ntsuas.

(8). Tom qab siv rau ib lub sij hawm los yog thaum peb pom cov roj ntsuas ntsuas yog insensitive, peb yuav tsum ntxuav lub xeem qhov nyob rau hauv lub xeem clip nyob rau hauv lub sij hawm.

(9). During using the apparatus, if appears fault, you should invite the professionals to repair and contact with us in time. If it's quality problem, we can offer the gratuitous warranty within one year.

(10). Rau qhov siv hluav taws xob, koj yuav tsum khaws cov av zoo.
