Temperature Products Series DT-8300 Digital Thermometers DESCRIPTION SPECIFICATIONS The AMETEK DT-8300 Digital Thermometer is a rugged, field instrument designed for dependable, worry-free temperature measurement anywhere in the plant. This unique device can be used with any Type K thermocouple to provide quick, convenient, Model DT-8300 continuous monitoring of liquid and gas processes. The DT-8300 is ideal for use in hard to reach places such as overhead pipes since it can be mounted remotely from the sensor by use of thermocouple extension wire. Four configurations provide for wall, pipe, panel, or stem mounting. The stainless steel housing and one piece VALOX® bezel/face provide a corrosion resistant package for harsh environments. This device performs reliably over a wide ambient temperature range. The large, easy reading LCD display features low power and open sensor indication. A self-powered version is available incorporating commercially available size AA batteries for approximately 1.5 years of continuous operation. An external power model is also available for operation with an unregulated 6 to 28 VDC power supply. The DT-8300 is also inexpensive, priced far less than comparable electronic field temperature instruments. RANGES: Low: -50ºF to 450ºF (-50ºC to 250ºC); High: 400ºF to 1500ºF (200ºC to 800ºC) INPUT: Type K thermocouple; supplied by U.S. Gauge distributor or customer, Type J and E inputs also available ACCURACY: Basic Accuracy: ±1% of full scale (excluding T/C error) Conformance (to ANSI MC95-1): Low Range: ±2.2ºF (1.2ºC) from –40ºF to 450ºF High Range: ±2.7ºF (1.5ºC) from 400ºF to 1500ºF Cold Junction Compensation And Zero Drift: .08 degrees (F or C) Span Drift: .008% of reading/ºF (0.015% of reading/ºC) Resolution: 1ºF (1ºC) CALIBRATION ADJUSTMENT: Screw adjust permits calibration to within 1ºF (1ºC) at any desired point OPERATING TEMPERATURES: -13ºF to 160ºF (-25ºC to 72ºC), depending on power supply SELF-POWERED VERSION: Battery, 8 Size AA: 1-1/2 years continuous operation, typical.
