Temperature and Humidity Data Loggers

WIDE TEMPERATURE RANGE

The TC-08 thermocouple data logger is designed to measure a wide range of temperatures using any thermocouple that has a miniature thermocouple connector. Additionally, the TC-08 can also measure other sensors using a 70 mV range.

Featuring built-in cold junction compensation (CJC), the TC-08 has an effective temperature range of -270 to +1820°C. (The actual temperature range depends on the thermocouple being used.)

ALL THE BENEFITS OF USB

The TC-08 connects to the USB port of a Windows-based PC and enables the host PC to automatically detect the TC-08, avoiding the need for any complex setup procedures. The USB connection also allows the TC-08 to be powered directly by the USB bus, eliminating the need for an external power supply and making the TC-08 ideal for measuring temperatures both in the lab and in the field.

TC-08 TERMINAL BOARD

This is an optional terminal board for the TC-08. The screw terminals allow wires to be attached to the data logger without soldering and enable the TC-08 to measure voltages from 0 to +5 V, or 4-20 mA loop current.

PT-104 USB PT100 DATA LOGGER

ACCURACY AND RESOLUTION

Although accurate temperature sensors are widely available, it has been difficult to find a measuring device that can take advantage of them without introducing excessive errors. The PT-104 USB, however, is inherently accurate due to its novel design. Rather than relying on voltage references (which tend to be temperaturesensitive) it uses ‘reference’ resistors which are extremely stable (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). To achieve the 0.001°C resolution, a highly advanced ADC is used that can resolve to better than 1 part in 16 million.

TEMPERATURE

The PT-104 USB measures temperature using platinum resistance thermometers (PRTs). Both common industry standards (PT100 and PT1000) are supported. The unit is compatible with 2, 3 and 4 wire sensors (4 wire PT100 sensors are recommended for accurate measurements). A wide range of PT100 sensors are available for use with the PT-104.

PT-104 SCREW TERMINAL ADAPTER

The PT-104 Screw Terminal Adapter is an accessory for the PT-104 Platinum Resistance Data Logger. The adapter allows PT100 probes that are not fitted with a mini-DIN connector to be used with the data logger without the need for any soldering.
