Introduction
DTMC Six-channel Precision Thermometer is a multi-function Measuring Instrument on modular design. The whole series is divided into four configurations: single-channel, two-channel, four-channel and six-channel. Platinum resistance measurement module, thermocouple measurement module or thermistor measurement module can be selected respectively, DTMC intelligent thermometer have many advantages such as high precision, wide sensor coverage and rich functions.
DTMC thermometer can be connected to the PC terminal or mobile terminal by wired or wireless way, suitable for thermostatic bath temperature field test, thermocouple furnace temperature field test, dry block furnace temperature field test, can be widely used in measurement calibration, scientific experiments and other precision temperature measurement related fields.

Function

Features

1. Outstanding noise reduction design
Multi-stage anti-aliasing design is adopted, which greatly reduces the noise level of the input channel and greatly improves the signal-to-noise ratio of the measurement results, making the noise level better than 0.1uV.
2. Excellent long-term stability
DTMC Multichannel Measuring Temperature Instrument adopts the classical ratio measurement principle, built-in reference level standard resistance, temperature coefficient as low as 0.1ppm/℃, the stability level is better than the general 7-bit semi-digital multimeter.
3. High precision thermocouple cold junction
Uses an independent high-precision digital temperature sensor as the cold end compensation sensor. The distance between the cold end temperature measuring point and the thermocouple connection point is less than 20mm. At the same time, combined with good temperature design, the thermocouple measurement channel can provide reference end compensation with accuracy better than 0.15℃.
4. Perfect parameter editing
Built-in a variety of common thermal resistance, 13 kinds of thermocouple and thermistor calculation formula, convenient connection of various types of temperature sensors.
Users can edit platinum resistance coefficient according to ITS90 and CVD formula, support standard platinum resistance, ordinary platinum resistance. Regular platinum resistors support editing R0, alpha, beta, and delta parameters.
Users can edit thermistor coefficients according to Steinhart-Hart equation.
5. Statistical data analysis
DTMC series intelligent multi-channel thermometer each channel has independent curve display and data analysis functions, users can view the maximum value, minimum value, average value, standard deviation and other statistical data of measurement data in real time. After the measurement starts, the measurement data is automatically saved to a file, and users can browse and analyze the historical data at any time.
6. Data encryption
It can provide encryption algorithm support, encrypt data files, and meet the special requirements for data security in special industries such as national defense and military industries.
7. Wireless LAN
DTMC series intelligent multi-channel thermometer can be connected to tablet or laptop computer through 2.4g wireless network, remote sharing of measurement data, effectively improve work efficiency.
8. Large capacity storage
DTMC series intelligent multi-channel thermometer has built-in 8G large capacity memory, and also supports usb disk storage function, which can easily import data into USB disk. The exported data can be browsed or processed by general tools such as Excel, or imported into special software for data analysis and report generation.
9. Rich and friendly human-computer interaction functions
DTMC series intelligent multi-channel thermometer adopts 7 inch touch screen design, providing rich and friendly human-computer interaction interface, operation interface content covers: Channel setting, sensor setting, statistical data display, curve display, unit switch, channel correction, channel calibration, file operation, system setting, etc., without the help of any other peripherals can independently complete the data collection work of the test site.
