TL2-A 2-Channel Calibration Lab. Reference

Product catalog summary

Specifications:
The TL2-A is a precision bench top thermometer with two 5-pin DIN connector channels, compatible with 100Ω and 200Ω RTD, PRT, or SPRT sensors. It offers a resistance accuracy of 20Ω +/-0.002°C, 100Ω +/-0.007°C, 190Ω +/-0.015°C, 265Ω +/-0.021°C, and 425Ω +/-0.032°C. The resolution is 0.001 degrees, with a temperature range of -328°F to 1764°F (-200°C to 962°C), depending on the sensor. It supports ITS-90 or Callandar-Van Dusen linearization equations.

Calibration and Data Logging:
Factory calibration is available for the -4°F to 572°F (-20°C to 300°C) range. Data can be captured to a USB flash drive in CSV format and transferred to a PC via HyperTerminal. The device supports selectable logging intervals and polling mode, with sensor coefficient entry via USB and included software.

Interface Features:
The unit features a large 0.5" (1.3cm) character LCD with backlight and a USB interface. It allows for switchable units between °C, °F, °K, or Ω, with resolutions of 0.01, 0.001, or 0.0001 for Ohms. It includes a zero set adjustment and a temperature-triggered SPDT relay output on Channel 1. The device stores and displays average, lowest, and highest readings, with arrows indicating temperature trends.

Construction:
The TL2-A is housed in a rugged powder-coated steel enclosure with silicone buttons and a durable polyester graphics window. It has nominal dimensions of 7.25 x 5.25 x 2.25" (18.4 x 13.3 x 5.7cm) and weighs 1lb. 10oz (0.74kg).

Applications and Industries:
Typical applications include distillations, temperature baths, melting point tests, flash point tests, reference, thermowells, provers, and temperature calibration for flow meters. It is suitable for laboratory, pharmaceutical, and food industries.

Additional Information:
The product comes with a one-year warranty, calibration report, USB cable, flash drive, interface software, and a country-specific power adaptor. Specifications are subject to change.
