HZYN-1301 ASTM D445 automatisk oljekinematisk viskosimeter

HZYN-1301 kinematisk viskositet Bath Astm D445 olje kinematisk viskosimeter

Disposisjon

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.

Bruksbetingelser

(1) Miljøtemperatur: 0 grader -40 grader

(2) Relativ fuktighet:<>

Oppmerksomheter

(1). Når det ikke er vann inne i akvariet, er det forbudt å slå på.

(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). Før vi bruker apparatet, må vi sørge for pålitelig jording.

(4). Når vi -starter apparatet på nytt, må bruksintervallet være over 15 minutter. Og apparatet startes i kaldt bad, og det må brukes etter 45 minutter.

(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). Forby å lagre eller bruke apparatet i det våte miljøet med den etsende gassen.

(7). Når vi klipper kapillæren, vær oppmerksom på høyden på øvre åpning og unngå å komme inn i vann i reagensrøret.

(8). Etter bruk i en periode eller når vi finner ut at oljenivåmålingen er ufølsom, bør vi rengjøre testhullene i testklipsen i tide.

(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). For strømkilden må du beholde god jording.
