WRS-3A Melting Point Apparatus Visual and Automatic Microprocessor High Efficiency
Introduction
The WRS-3A Melting Point Apparatus is equipped with a PID (Proportional-Integral-Derivative) temperature control system, representing an advanced iteration of the original WRS-3 model.
This apparatus has the capability to measure up to three samples at once and calculate their average values.
It features a color LCD touch screen display and comes with a variety of communication interfaces for data storage and export.
The instrument utilizes capillary tubes as sample tubes, which are specified by pharmacopoeias.
The most significant feature of the apparatus is the combination of visual and automatic measurement methods. It integrates visual observation measurement with photoelectric detection automatic measurement into a single device. This dual functionality offers the convenience of automatic melting point determination through photoelectric detection while also allowing for visual measurement of substances, which is particularly useful for measuring the melting points of dark-colored samples. As a result, the WRS-3A has an extensive range of sample measurement capabilities and is highly user-friendly.
