ASTM D1287 pH Apparatus of Engine Coolants and Antirusts
This instrument is suitable to determine the pH of unused engine coolants and antrirusts,and used or unused aqueous dilutions of the concentrated products.But it can not be used for solid antirusts.
When equipped with relative ion selective electrode,it can measure many ion concentration.It can also work as displayer of potentiometric titration measurement.It has function of temperature measurement.
1. The pH apparatus can be calibrated automatically,and the procedure is started by combination key.It can effectively avoid loss of calbration data for wrong operation.
2. There are 3 groups standard solution which can be chose as per different requirements in each country.
3. Display of electrode status and slope can remind the using condition of electrode at any time.
4. Auto End Lock can eliminate effor of human reading.
5. It can measure pH,ORP and ion concentration with standard curve method.
6. Intelligently switch manual and auto temperature compensation.
7. This pH tester can store calibration data for 10 years.
8. It's equipped with RS232 communication port.
