Model MPC-602/302/102 has been designed for automatic determination of Pour Point (PP) and Cloud Point (CP) with small specimen size and shorter test time while securing better test precision than the conventional manual method. PP measurement is made by utilizing a new automatic method, (Air Pressure method), which yields no bias against the conventional test method’s, repeatability of 1°C, and reproducibility of 2°C.(*) This epoch-making accuracy has made possible PP determination at 1°C intervals. The CP/PP mode executes a CP determination and then a PP determination consecutively, which further improves the test throughput. The MPC-602 is a 6 test version and the MPC-302 is a 3 test version of the original single test model (MPC-102). ASTM has approved the PP test method: ASTM D6749 on “Standard Test Method for Pour Point of Petroleum Products (Automatic Air Pressure Method)”. *Accuracy information is for typical samples.

Easy Sample Handling: Since the required specimen volume is a mere 4.5 ml and the specimen cup is a test-tube type removable jar, the sample handling is extremely easy.

Easy, Quick, and Precise PP/CP Determination: Just set up the specimen, set test parameters, and then press the START key to start a test. The specimen is cooled at the steepest possible rate without affecting the formation/growth of wax crystal, which has been known to be critical in PP/CP determination. For fuel oils, the specimen may be even pre-heated automatically and then cooled for CP/PP determination, which further improves test throughput.

*:Sample viscosity, etc. affects lowest temperature of the measuring range.

Measurement Modes:
Selectable from various modes.
1. CP mode
2. PP modes: Programmed by the user. Programmable parameters are:

• Amount of applied air pressure for PP detection, to accommodate different sample types: L(low) for diesel fuels, H(high) for lube oils, VH(very high) and UH (ultra high) for residual fuels and similar samples.
  
• Testing intervals: 1.0°C, 2.5°C, or 3.0°C (In total, 4x3=12 modes for PP.)

3. CP/PP modes: CP is determined and then PP.
PP detection is programmable by the user with the
same parameters as PP modes. (12 modes in total.)

Automatic Sample Pre-Heating:
Automatic preheating at either +45°C or EPP+10°C. (EPP=Expected Pour Point)

Test parameters, EPP, bath temperature, sample temperature, PP, and CP displayed on VFD. Temperatures displayed with 0.1°C increments.

Printer: (built-in)
PP, CP, mode, EPP, etc. printed by thermal printer.

EPP Setting:
EPP(Expected Pour Point) needs to be set prior to test starts.

Specimen Cup:
Cylindrical glass test jar with 4.5ml sample volume.

Sensors:
Compound type sensor assembly for PP and CP. PP detected by air pressure method (patented). CP detected photo-electrically. PT100 temp. sensors.
