Hitachi High-Technologies GLOBAL

Simultaneous Thermogravimetric Analyzer (STA) STA7000 Series

Newly developed simultaneous thermogravimetry(TG,DTA), differential thermal analysis (DTA),and Differential Scanning Calorimetry(DSC)with high performances. µg level weight changes can be detected and precisely measured with high sensitivity horizontal balance systems. The base line performance is improved by adopting newest digital technology.


1. New Balance Control Technology

The newly-developed “Horizontal Digital Dual Beam System” guarantees the highest baseline stability and the lowest noise levels ever seen in TG (TGA) analysis.

Structure of TG/DTA

Baseline Stability

2. New Temperature Control Functions

This revolutionaly temperature control circuit minimizes the temperature difference between program and sample temperrature.The heating and cooling rate accuracy further improve the quality of the DTA/DSC and TG signal and guarantee high precision temperature readings.

Realized High Cooling Rate

3. High Throughput Measurement with Full Line-Up Options

Newly developed Auto-sampler system and MASS flow control technology can satisfy variety application requirements.

4. "Real View STA" Sample Observation Option

Real View STA displays and saves the changes of samples during a measurement by linked images. After the measurement, you smoothly display and analyze by loading the saved image using analysis software and linking to temperature and each signal. More highly reliable information is obtained for evaluating thermal analysis behavior.
