PT104 Platinum Resistance (PT100/PT1000) Temperature, Voltage & Resistance Data Logger

4 channel PT100/PT1000 data logger, for use in precision temperature measurements, Along with temperature it can also be used to measure resistance and voltage.

PT-104 Data Logger

The PT-104 is a four-channel temperature measuring data logger. It offers the ultimate in resolution (0.001 °C) and accuracy (0.015 °C). Along with temperature it can also be used to measure resistance and voltage.

Platinum Resistance Data Logger

  • Measures temperature, resistance and voltage

  • Works with PT100 and PT1000 sensors
  • Supports 2, 3 and 4-wire sensors
  • No power supply required
  • USB and Ethernet interfaces
  • Run multiple units on a single PC

Accuracy and resolution
Although accurate temperature sensors are widely available, it has been difficult to take advantage of them due to errors caused by the measuring device. Your PT-104, however, is inherently accurate due to its innovative design. Rather than relying on voltage references, which tend to be temperature-sensitive, it uses reference resistors, which are extremely stable with low temperature coefficient and drift. The exact value of each resistor is stored in an EEPROM to provide the ultimate in accuracy (yearly recalibration is recommended). A high-performance 24-bit ADC is used to achieve the 0.001 °C resolution.

Optional Temperature Kit
