HFN-B portable viscometer

HFN-B portable viscometer uses capillary method to determine the kinematicviscosity of oil at 40 ° C, allowing users to quickly and accurately judge the changeof kinematic viscosity of oil, improve equipment reliability, and avoid the loss causedby equipment downtime. Users can customize the viscosity index, and automatically calculate the kinematic viscosity at 100 ° C based on the viscosity index andkinematic viscosity at 40 ° C. The instrument has multi-point correction function toensure the detection accuracy of the instrument.

Capillary method: Almost any type of oil can be detected; Open and close: will not cause capillary blockage Multi-point correction: use standard oil to correct a certain viscosity range toimprove the detection accuracy of the viscosity range; High detection accuracy: the measurement accuracy is consistent with thelaboratory bench equipment; No need for solvent: no need for any solvent cleaning, just clean oil absorbentpaper wipe can be more environmentally friendly; Small sampling amount: Only use a disposable straw to drop 2 to 3 drops of the oilto be tested into the capillary tube to complete the entire detection process; Simple operation: Touch screen interface is friendly, without complicated operationprocess can complete the detection; Compact and lightweight: the instrument weighs about 4.2kg; Long battery life: lithium battery life of more than 8 hours.

Hardware function description 

The hardware part of the HNF-B portable viscometer is mainly composed of a maincase, detection sensor, touch display, small printer, function buttons (power buttonand start/stop button) and AC socket. 

Software Function Description

There are three main functions of the software: 

- - Oil testing; 

-- viscosity correction; 

--Print. Operation process 

- - Turn on the power switch of the device; 

-- Wipe the sensor detection area to prepare for detection; 

- - Click the "Start Stop" button on the screen or the "Start Stop" button on the panelto start the operation;

- The system automatically enters the "preheating" state, when the oil passagetemperature reaches 40±0.5°C, the system automatically enters the "oil injection"state; 

-- When the system enters the "oil filling" state, the system prompts the user to"inject oil sample..." At this time, disposable pipette can be used to absorb the oilsample to be detected, and the oil sample is continuously dropped into thedetection tank; 

-- Wait for the completion of the test; 

-- After the sample test is completed, the current kinematic viscosity value will beautomatically displayed on the screen;

- - The user can record or print the test data, or enter the setting interface forviscosity correction; 

- - If you need to test again, wipe the sensor detection area and restart the test; 

- - After the detection is completed, wipe the sensor detection area and turn off thepower supply of the device.

Precautions for Use 

When detecting the same sample, the first 2 groups of detection data should beeliminated, at least 3 times of detection data should be taken, and the average valueshould be taken as the final structure; When dropping into the sample, ensure that there are no bubbles in the samplepool, otherwise the test result will be affected; When conducting sample testing, ensure that the equipment is in a horizontal stateto ensure that the sensor is in a vertical state of detection; Do not use paper that can produce lint to wipe the sensor detection area;
