Introduction
This relative density test apparatus is combined requirements of Chinese standards and ASTM D standards.It adopts densimeter to determine relative density of engine coolants and engine coolant concentrates.The structure is separated,and operatio is easy.It is highly improve the working efficiency.
Characteristic
>1. >Standard glass tube can meet requirements of ASTM test method.
>2. >Glass bath allows transparent observation,the operation is easy,
>3. This apparatus adopts fully closed air compressor refrigeration.
>4. >The cooling medium is cycles with noise-free circulating pump,
>5. >Heater is stainless steel.
>6. >Structure is separated,and it is easy to move.
>7. >There is hole on the cooling bath to add cooling medium,it can be added at any time if medium is lost.
>8. >Micro-computure controlling,PID function,digital tempeature display(continuous display during test),accuracy 0.1℃,Pt100 RTD temperature probe.
>9. >Contact control box is very convenient.
>10. >Over-heat safety protection device.There are low liquid level alarm and automatic liquid level adjuster in water bath,
