The DL-GT-DT4947SD is a general-purpose handheld instrument that can measure up to four channels of temperature with 0.4% accuracy using either thermocouples or RTD's (Pt 100 ohm probes).
Although thermocouples are not as accurate as other types of thermometers, they more than make up for this shortcoming with an extended measurement range. For example, the DL-GT-DT4947SD can measure and read out temperatures from -148° to 2372°F (-100° to 1300°C) using Type K thermocouples, and temperatures from -148° to 2192°F (-100° to 1200°C) using Type J thermocouples. Type R and Type S thermocouples have an even higher upper limit. These very wide ranges, plus a fast response time and a low price tag, suit thermocouple thermometers for a variety of commercial and industrial tasks requiring measurement of very high and low temperatures. Examples include applications in the food and chemical processing industries, HVAC (heating, ventilation and air conditioning), power generation and paper production.
Because it is microprocessor-based, the DL-GT-DT4947SD can make full use of the portability, reliability and large storage capacities that SD memory cards offer (Up to 16 GB). Measurements can be made automatically at any sampling rate between one second and one hour. After timestamping and storing the measurements on an SD card plugged into the instrument, the user can remove the card and plug it into to a laptop or desktop computer either directly or through an SD card reader. The data logs are stored on the card as files with the .xls extension, which can be opened by Microsoft’s Excel application.
The DL-GT-DT4947SD has advanced settings. The user can set the clock (Year/Month/Date, Hour/Minute/Second), SD card setting of decimal point, set BEEP sound either off/on, set C/F, set AUTO POWER off/on, and set sampling time.
The DL-GT-DT4947SD has a backlit 2-1/2 in. diagonal display and is powered by six “AA” Alkaline batteries or an optional 9-VDC AC adapter.
