Measurement channels:20 channels RTD / 40 channels thermocouple test channels, 8 channels humidity test channels
| Sensor Type | Measurement Range | Resolution | Accuracy |
|---|---|---|---|
| RTD (Pt100) | (-200 ~ 800) °C | 0.01 °C | ±(0.01% RD + 0.05) °C |
| Thermocouple (Type S) | (100 ~ 1800) °C | 0.01 °C | ±1.2 °C |
| Thermocouple (Type N) | (-200 ~ 1300) °C | 0.01 °C | ±0.6 °C below 600 °C / ±0.1% RD above 600 °C |
| Humidity Sensor | (0 ~ 100) %RH | 0.1 %RH | ±0.8 %RH |
Scanning speed:0.1 second per channel
Integrated design:Instrument and enclosure integrated, compact structure, small size, easy to carry
Built-in large-capacity rechargeable lithium batteryfor use in environments without AC power; battery charges simultaneously when external power is connected
Wide temperature and humidity measurement rangecovering (-200 ~ 1800) °C and (0 ~ 100) %RH
Up to 28 channelsof simultaneous temperature and humidity measurement, including 20 temperature channels and 8 humidity channels; temperature channels can be flexibly configured as 4-wire RTDs or thermocouples, with automatic cold junction compensation for thermocouples
Imported high-accuracy humidity sensorseliminate the operational complexity of traditional wet-and-dry bulb humidity measurement methods
Manual and automatic correction functionsfor more accurate test results
Automatic temperature and humidity data acquisitionwith display in both curve and table formats; different colors for different channel curves, with customizable curve colors; curves can be recorded, zoomed infinitely and panned for convenient observation of temperature and humidity changes
Sensor layout schemes can be savedfor easy recall in subsequent tests
Powerful database managementstores years of test data; periodic testing can be performed automatically without re-entering sample information
Curve data import and exportin CSV format, openable in Excel for easy data exchange with other software
Data traceability function:Users can query measurement data at any point in historical records at any time
Automatic calculationof temperature and humidity deviation, uniformity and fluctuation; as well as maximum, minimum and average values; automatically generates calibration original records meeting national laboratory accreditation requirements
Data cropping function:No need to wait for temperature and humidity to stabilize before recording data. Real-time data can be recorded throughout the process, then visually cropped afterward, with 15 sets of calibration data regenerated based on the cropped region
Dedicated USB interfaceon the main unit — data can be saved to a USB drive first, then imported to a computer for cropping and generation of original records
Dimensions:400 × 150 × 260 mm
