HN-GP-2 Automatic Expansion Number Tester

Introduction to HN-GP-2 Automatic Expansion Number Tester:

The instrument furnace body adopts special insulation materials and heating furnace wires, with good insulation performance, long service life of furnace wires, and easy replacement. The temperature controller is equipped with the ATC series products that have been identified. Based on the characteristics of measuring the expansion number of bituminous coal crucibles, in addition to retaining the features of this series of temperature controllers such as using high-precision thermocouple cold end compensators, the temperature control program has been modified to add a preheating, constant temperature, and testing time display unit. The HN-GP-2 type (formerly GPX-II type) (ZP-II is an integrated furnace type) has been improved based on the GPX-I type, adding a memory function and becoming a new self memory instrument - that is, users can demonstrate how to control the furnace temperature to the instrument, and the temperature controller can immediately remember the entire temperature control process. If the user makes new changes to the temperature control process, the instrument will remove the old process and automatically update to the new temperature control process.
