TL3-W Ex Field Reference Thermometer

Product catalog summary

Construction and Design:
The TL3-W thermometer features a weather-resistant enclosure with a stainless steel RTD temperature sensor. It includes a 100Ω shock-resistant thin-film RTD available in standard lengths of 8" (20cm) or 12" (30cm) and a diameter of 0.25" (6.35mm) with a reduced tip of 0.188" (4.76mm). The housing is made of static-dissipative plastic with a durable polyester graphics window. The nominal body dimensions are 5 x 1.75 x 1.15" (13 x 4.4 x 2.9cm) and it weighs 5.5 oz (156 grams).

Applications:
This thermometer is suitable for distillations, temperature baths, melting point tests, flash point tests, reference, thermowells, provers, and temperature calibration for flow meters. It is used in industries such as laboratory, petroleum, pipeline, pharmaceutical, and food.

Temperature Specifications:
The TL3-W offers an accuracy of +/-0.1°F (0.06°C) with a standard calibration range from 14°F to 320°F. It includes a 4-point calibration at 32°F (0°C), 120°F (49°C), 199°F (93°C), and 300°F (149°C). The resolution is 0.01 degrees, and the range is -40°F to 400°F (-40°C to 204°C). Custom calibration points and ranges are available. The temperature time constant is 6 seconds in a circulated water bath, with a recommended minimum immersion depth of 3" (7.6cm).

Battery and Power:
The device is powered by 2 AAA Duracell MN2400 batteries, offering over 450 hours of service life at 70°F (21°C). The ambient temperature operating range is -4°F to 130°F (-20°C to 54°C), with a note that the battery may not provide adequate power outside this range.

Certifications and Features:
The TL3-W is intrinsically safe and certified for hazardous locations (Ex). It is a weather-resistant upgrade from the TL3-A, featuring Bluetooth® connectivity, a large display, and an easy-to-hold design. The rugged plastic alloy case and buttons are suitable for industrial applications. The thermometer offers improved temperature accuracy, response time, battery life, and Bluetooth® monitoring. It includes versatile software functions for unit selection, display resolution, and Bluetooth® activity. Minimum, maximum, and average temperatures are stored for later reference. The device includes low battery and fault indications, and encoded calibration is unaffected by temperature, vibration, or battery removal.

Interface Features:
The TL3-W has a 0.5" (12.7mm) character LCD, switchable units between °C and °F, resolution options of 0.1 or 0.01, and a Bluetooth® wireless transmitter. It features low battery and fault indications, continuous operation or auto-off after 20 minutes, and stores and displays average, lowest, and highest readings. Arrows indicate increasing or decreasing temperature. The recommended ambient temperature range is 32°F to 112°F (0°C to 44°C).

Additional Information:
The TL3-W comes with a one-year warranty, a protective case, and an NIST traceable 4-point calibration report. It is supported globally through distributors equipped for calibration and repair.
