Product Description

1. Description
HTD13285 digital rotational viscometer is a new model viscometer designed by our company. It adopts embedded type structure,internal high precision angle sensor and step drive which makes rotational speed more steady and precise; panel buttons are so clear that it can be easy to operate; high resolution LCD can display testing drilling fluid's viscosity value and mixing speed. 
It can be widely used in oil, chemical industry, food, medicine and cosmetics and scientific research sites.
Working principle: Put testing liquid cup on the tray. Pour testing liquid into annular space forming from changing rotor and bobs. When stepping motor makes changing rotor rotate,changing rotor in testing liquid produces courter force under viscous resistance, which will produce torque to bobs in changing rotor through testing liquid. And bobs connect with a set of scale components. When the torque and viscous resistance reach the balance, scale components will be on a scale value. Since scale value is in proportion to viscous resistance, so the scale value times specific coefficient is final viscosity, At the same time, which will be displayed on LCD.
There are simple linear corresponding relationship between shearing rate and viscosity value which means shearing stress and shearing rate's relationship diagram is line.  In practical application, much fluid may be not follow
Newton's laws of motion, but rheology is close to Newton's laws of motion, so viscometer can be used to test and viscosity value we got is accurate. HTD13285 digital rotational viscometer's calibration is linear calibration of Newton which is not applicable for testing sample not conforming to Newton linear calculation. In this conditions, viscosity measurement  and speed calculation should use nonlinear calculation.  
When changing rotor,bobs and torsional spring rotate in 300 revolution/minute, measurement unit of viscometer is centipoise. The testing data in other speed need to do multiply conversion.The sixth part will give pseudo plastic fluid's viscosity calculation.
When you choose different rotational speed or use different torsion spring-bobs, shearing rate's selected range may be changed. To broaden the range of shearing stress and measure more liquid, you can change different torsion springs to do it.
 
Company introduction

Haitongda special instruments Co., Ltd is one of the earliest manufactory in drilling fluid, completion fluid analysis instruments and oil well cement testing instruments. With professinal technology and quality. Our company was founded in 1978, its predecessor is Qingdao camera factory which was a large state-owned enterprises. In1996 Qingdao camera factory took over of the Hisense group company then changed its name to Qingdao Hisense Optical Co., Ltd. In 2001 the enterprise again integrate, approved by the Qingdao Municipal Administration of industry and Commerce changed its name to Haitongda special instruments factory. Our company has perfect organization management mechanism and production process, quality management system. The main business includes: Development and production of equipment and oil well cement testing instrument of drilling fluid, completion fluid analysis. All kinds of analysis, our company according to the API standard production test instruments series products are widely used in national each big oilfield, the geological department, chemical unit, has won a good reputation.

Enterprise core concept

Products

Haitongda special instruments factory began production of drilling fluid analysis instruments since 1978. So far has a total of drilling fluid and completion fluid analysis instruments and oil well cement testing instrument and a total of 3 categories and 22 items of more than 120 kinds of products.

Chronicle of enterprise

Qingdao Camera Factory 1978 started development and production of analytical instruments of drilling fluid. Overall under 1994 years of camera factory in Qingdao Hisense Group, renamed hisense Optical Co., Ltd. Enterprises in 2001, the establishment of Haitongda special instruments factory; Eastern part of the new plant is ready for use. Commencement of full-scale research and development of Oil Well Cement testing instruments in 2001. In February 2002 the first EP lubricant Tester developed and put into mass production, become a substitute for imported products. In 2003 the successful development of drilling fluid lubricity for DLA analyzer product appraisal meeting held in September of that year at the factory, Qingdao Science and Technology Bureau and relating to the participation of experts in oil field, a one-time qualified and put into mass production. Oil Well Cement testing instrument into mass production in 2004. NP series of expansion Measuring Instrument Development, Production in 2005. Products are exported to over 5 million yuan in 2006. To export small quantities of Oil Well Cement testing instruments in December 2007. Corporate share capital increase in March 2011 and renamed Haitongda special Instruments Co., Ltd.
