Melting point meters

for the determination of the melting point of pulverized substances in glass capillary tubes for identification of the substance.

Principle:
After setting the start temperature (approx. 3 °C less than the expected melting point) the capillary is to be inserted and observed while the instrument is heating up with a heating rate of 1 °C per minute. Report printing can be produced by MPM-software supplied for both models.

Modell MPM-H3
for visual measuring method by observing the specimen in the capillary through a magnifying glass. After reaching the melting point temperature is shown on the digital display.
The instrument allows up to 3 successive readings. 

Modell MPM-HV3
for optional measurings visual (as model MPM-H3) or fully automatic with graphic presentation of the substance's change during the measuring process.

• tracing the report to the device is guaranteed by indicating the device's version with serial number on the report
• supervision of the calibration due date by indication on the report
• matching of the examined substance and the verifying person by mandatory fields in the software
• antiglare lighting of the substance during visual measuring
• digital control of temperature
• foil keyboard for easy cleaning
