Product Introduction
I. Features and Functions:
1. Model Classification and Description:
JWM32R3: 32 channels, resistance-type sensors, 3-wire input
JWM24R4: 24 channels, resistance-type sensors, 4-wire input
JWM24C4: 24 channels, thermocouple-type sensors, 4-wire input
2. Has electronic circuit temperature drift self-correction function;
3. Has strong anti-interference capability;
4. Linearization function. Sensors can be calibrated, and the calibration data can be input into the instrument for curve fitting to achieve ultra-high precision measurement;
5. Maximum number of acquisition channels: 32 or 24;
6. Each channel has independent over-temperature upper and lower limit alarms (upper and lower limits can be manually set) and channel data acquisition anomaly alarm functions;
7. Automatic and manual recording functions. Data can be manually viewed or read by a computer. Large storage capacity, can store more than 1000 data points. Recorded data can be plotted as trend charts;
8. Equipped with RS485 interface, sampling data and recorded data can be read via a host computer;
9. Perpetual calendar function. Can be used to query recording times. The instrument has a built-in large-capacity rechargeable battery, so even if it is left unpowered for a long time, the perpetual calendar will not become disordered or fail;
10. 12864 dot-matrix LCD large screen display, can display data from 8 channels simultaneously;
11. Power supply voltage: 220VAC
II. Suitable Ambient Temperature: 0～60℃。
III. Applications:
1. Suitable for most temperature measurement applications.
2. Suitable for precise temperature measurement, such as sterilization cabinet temperature field validation, cold storage temperature field acceptance, soil temperature measurement, ice rink temperature measurement, etc.
3. Suitable for temperature calibration at different points in a temperature field.
4. Suitable for surface temperature measurement (recommended). When used with ultra-fine thermocouple wires, the JWM24C4 can perfectly overcome the effect of heat dissipation on surface temperature measurement, achieving fast and precise surface temperature measurement.
IV. Factory Settings
At the factory, designated channels can be set to connect thermocouples or thermal resistances according to user needs, achieving efficient mixed use.
