NM-LQ200 Asphalt Softening Point Test Instrument Temperature Calibration Device
The NM-LQ200 asphalt softening point testing device temperature calibration device is designed according to JJG (Transportation) 057-2017 calibration regulations for asphalt softening point testing instruments. It is suitable for verifying the heating rate and the error in the softening point temperature readings. The instrument is designed to be compact and lightweight, weighing only 2kg, making it suitable for on-site calibration work.
NM-RTS series refrigeration low temperature constant temperature bath
This series of constant temperature baths is mainly used for the verification and calibration of thermistors, low-temperature thermocouples, glass liquid thermometers, bimetallic thermometers, pressure thermometers, etc. It can also provide a constant temperature source for other experimental research work. The dual-tank stirring operation mode separates the verification working area from the heating and cooling mixing area of the constant temperature bath, reducing operational noise, improving the technical performance of the device, and expanding the effective working area. It uses a Pt100 platinum resistance temperature sensor and an intelligent PID controller to achieve automatic temperature control, featuring short transition time, long stability time, and high reliability.
NM-HTS series precision constant temperature bath
This series of constant temperature baths is mainly used for the verification and calibration of thermistors, low-temperature thermocouples, glass liquid thermometers, bimetallic thermometers, pressure thermometers, etc. It adopts a dual-tank stirring working method, separating the verification working area from the heating and cooling mixing area of the constant temperature bath, which reduces operational noise, improves the technical performance of the device, and expands the effective working area. It uses a Pt100 platinum resistance temperature sensor and an intelligent PID controller to achieve automatic temperature control, featuring short transition time, long stability time, and high reliability.
NM-HYC Constant Temperature Salt Bath
Our company's latest high-temperature salt bath uses molten liquid salt as the medium, supplemented by mechanical stirring, creating a high-temperature field that can rival the uniformity of constant temperature oil baths, easily reaching 550°C. This represents a significant breakthrough in the temperature measurement industry, meeting the calibration needs of high-temperature platinum resistance thermometers and digital thermometers. The device features an industrial-grade touch display, multiple heating groups, and multiple sensor groups, fully automating the processes of melting, temperature control, and safety protection, making the use of the salt bath as convenient, quick, and safe as using an oil bath.
NM-RTS/HTS/HYC M series portable constant temperature bath
The NM-RTS/HTS M series portable constant temperature bath is a high-precision automatic temperature calibration device, featuring good temperature stability, uniform temperature field, and high temperature control accuracy. The RTS series uses an imported fully enclosed compressor refrigeration system, with an intelligent PID controller for automatic temperature control. The tank structure is compact, lightweight, easy to carry, and durable.
NM-JDL series medium temperature thermocouple calibration furnace
The NM-JDL series thermocouple calibration furnace is mainly used for the calibration of inexpensive metal thermocouples (types K, E, J, N), working precious metal thermocouples (types S, R), and standard thermocouples (types S, R) within a temperature range of 300-1200℃.
