PT-104 — High-accuracy Temperature and Resistance Data Logger
Four-channel high-accuracy platinum resistance temperature logger for PT100/PT1000 sensors and resistance measurement, with 0.001 °C resolution, 0.015 °C accuracy, 24-bit ADC, USB and Ethernet interfaces.
| Model | Channels | Sensor Types | Resolution | Interfaces |
|---|---|---|---|---|
| PT-104 | 4 channels | PT100 / PT1000 | 0.001 °C | USB / Ethernet |
Key Features
High-accuracy PRT Logging
Designed for PT100 and PT1000 platinum resistance thermometers where measurement precision matters more than high speed.
0.001 °C Resolution
A 24-bit ADC and stable reference-resistor design support very fine temperature resolution.
2-, 3- and 4-wire Support
Works with two-, three- and four-wire sensors; four-wire PT100 wiring is recommended for best accuracy.
Resistance Measurement
Also measures resistance using a four-wire circuit, with 0 to 375 Ω and 0 to 10 kΩ ranges.
USB and Ethernet
Use USB for portable local logging or Ethernet for remote/networked monitoring.
Multi-unit Expansion
Use multiple PT-104 units together for larger PT100/PT1000 data acquisition systems.
