1 Introduction
ZF-DSC-D1 differential scanning calorimeter has intelligence, small size, low price three greatest characteristics of thermal analysis instrument. Specially using to measure oxidation induction time of polyethylene, curing percentage of epoxy, anti-oxide of lubricant etc. ZF-DSC-D1 differential scanning calorimeter mainly express to following characteristics:
Small size of body;
It can quickly rise, reduce the temperature;
High resolution A/D(24 bits) data sampling;
Intelligence temperature controller of the microprocessor system, the accuracy of the constant
Temperature can reach to 0.1 degree over a long period of time because using PT100 platinum electric resistance and intelligence temperature controller;
Adopt numerical mass flow-meter by computer control;
High accuracy low drift amplifier;
Differential scanning calorimeter is including data processing system and software of. Oxidation induction time.

Main technique specification
Heating rate: 1~30 degree per min;
Crucible material and size: Aluminum ¦µ 6.7 mm × 2.5 mm;
Gas flow rate: Less than200 ml per min (nitrogen or oxygen gas channel can change each other);
Gas pressure: 0.2MPa.
Data processing system
Data sampling, saving, the screen showing and report as a result, temperature
Calibration and the processing of oxidation induction time
The instrument condition
Relative humidity: 55 ~75%
Power Source: 220 V, 50 Hz, the power supply needs credibility to connect ground
Place the instrumental work pedestal in response to the hard credibility, it can not have the influence of strong vibrate, strong electricity, the existence of the strong magnetic field interference.
