HZYN-1301 ASTM D445 Automatski kinematički viskozimetar ulja

HZYN-1301 Kinematički viskozitet kupka Astm D445 Kinematički viskozimetar za ulje

Outline

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.

Uslovi korišćenja

(1) Temperatura okoline: 0 stepen -40 stepeni

(2) Relativna vlažnost:<>

Pažnja

(1). Kada nema vode u akvarijumu, zabranjeno je paljenje.

(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). Prije upotrebe aparata moramo osigurati pouzdano uzemljenje.

(4). Kada ponovo-pokrenemo aparat, interval upotrebe treba biti iznad 15 minuta. A aparat se pali u hladnom stanju u kupatilu i treba ga koristiti nakon 45 minuta.

(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). Zabranite skladištenje ili upotrebu uređaja u vlažnom okruženju sa korozivnim gasom.

(7). Kada kopčamo kapilaru, obratite pažnju na visinu gornjeg otvora i izbegavajte da voda uđe u epruvetu.

(8). Nakon određenog perioda upotrebe ili kada utvrdimo da je mjerenje nivoa ulja neosjetljivo, trebali bismo na vrijeme očistiti probne otvore na ispitnoj kopči.

(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). Za izvor napajanja morate imati dobro uzemljenje.
