The Datatest Model DT5000 Microprocessor NOx analyzer utilizes a chemiluminescent detector (CLD) for precise continuous measurement of the NOx concentration in stack gases.
The Model DT5000 analyzer delivers accurate measurement over a wide range. The range is selected via the keypad and a backlit LCD display.
The 4 row by 20 character backlit LCD provides a continuous readout of the measured gas plus status such as alarms. The LCD and keypad also provide a pathway for calibration mode, and all other programmed parameters.
The Model DT5000 has scales starting at 0-100 ppm full scale up to 0-1,000 ppm. The analyzer can be configured starting with a full scale of 0-10 ppm as an option. Outputs on the system include 4-20 mA and a 232/485 Modbus serial port.
Datatest has chosen the molybdenum catalyst to be used in its heated, temperature controlled converter since it offers prolonged system life, high efficiency (over 95%) and freedom from interferences that traditionally have affected other types of converters. Along with the Micro-controller the Model DT5000 is one of the easiest NOx analyzers to set -up and get on line, in a package that is compact and light compared to others.
