Han was TYHW-V automatic calorimeter is the use of chip technology developed multifunctional calorimetry instruments. With a test of high precision, stable performance, system constants and experimental results can be stored for a long and after shutdown is not lost and so on. The instrument uses a liquid crystal display, intuitive display, easy to operate. Equipped with a serial printer, the experimental results at a glance. The machine has a powerful storage capabilities, recent experimental results are recorded, so that the query, a great convenience to the operator. Calculation program crafted to improve the calculation accuracy, even without adjusting the water temperature in the cylinder can be obtained satisfactory results. The instrument uses a dual probe, 18B20 digital temperature does not have to AD conversion, the simultaneous determination of the temperature of the inner tube and the outer tube, saving a special time to enter the outer cylinder temperature. Controller and host the perfect combination as a whole, beautiful, practical, space-saving
