Digital Melting Point Tester              
Application:
WRS-100 is a economic and easy-use melting point device. With a precise thermistor control system, the measurement range of the device is excellent, giving 0.1ºC resolutions on display.
The device is designed to simultaneously measure two samples. The internal LED light source, together with clear magnified lens and tilt rear feet aids users to have a broader and clearer view.
The measurement ranges from room temperature to 300ºC. The two different ramping speed modes make measurement much quicker and convenient.

WRS-100, WRS-200

WRS-300

WRS-200 is the upgrade version of WRS-100 and has following more features:
1. Built with internal fan to speed up the cool down process of the machine. The cooling rate is 25ºC/min.
2. The cooling process is automatically stared when the analysis process ended, and the fan will be turned off when the temperature reaching 5ºC below fast stage temperature. It will help user quickly to do the next analysis.
3. Double display in both outside and inside view. It help user frequently prevent frequently switching gaze between eyepiece and outside LED display.
4. A hand-held “READ” push button helps users to record data quickly without looking for the “READ” button in the fascia.
5. Capable of recording data. Data will be stored permanently until erase.

Automatic Digital Melting Point Tester with Printer RD-1              
Descriptions:
Melting point is the temperature of something turning to liquid from solid. Testing it is the main method to detect some characters, such as purity etc. The tester is suitable for testing melting point of drug, spice and dye etc.

Features:
1. Testing the temperature with high-precision sensor, emending nonlinear error
automatically.
2. Using auto frequency-conversion control technology with high accuracy in controlling
Temperature and little linear error in heating speed.
3. Auto-memorizing and nothing preset data and melt point, holding without power. With mini printer.
4. Auto magnetism stirrer, with the bath oil even in temperature.
5. Auto-preset temperature, auto-heat, display preset and real-time data alternately in time.
6. Automation: auto-test, auto-diagnose, auto-alarm.
