KT19.xx			several spectral response bands possible, temperature range depending on application

Temperature range	Depends on model, minimum and maximum measuring temperature; see table above
Temperature resolution (NETD)*	Depends on model, detector size, measuring temperature and response time; typical value ±0.1°C
Accuracy	±0.5°C plus 0.7% of the difference between target temperature and housing temperature
Long-term stability	Better than 0.01% of the absolute measured temperature in Kelvin/month
Lenses*	Several far-focus and close-focus lenses with different optical characteristics are available, including vacuum tight lens barrels
Field of view*	Depends on model, detector and lens type. For close-focus lenses: from 0.7 mm diameter at <20 mm distance; for far-focus lenses: typically 10 to 20 mm diameter at distances >1,000 mm.
Aiming options	Optional thru-the-lens sighting with integrated temperature indicator; alternatively built-in laser pointer; or focus laser. Other optional aiming aids (optical or mechanical)
LCD display on rear panel	Indicating measured temperature, emissivity, high/low alarm, programming menu
Keyboard on rear panel for programming of	Emissivity, background temperature compensation, analog output, response time, temperature unit, serial interface, read-out of miximum/minimum value, calibration procedure, on-/off-switch for laser pointer
Emissivity setting	Adjustable from 0.100 to 1.000 in 0.001 increments. Reflectivity and Transmissivity compensation
Response time	Selectable: 5mS, 10mS, 30mS, 100mS, 300mS, 1S, 3S, 10S, 30S, 60S, 120S, 240S, 360S, 480S, 600S for T₉₀
Analog output	4 scalable output signals: linear voltage or current, 0-1(10)V or 0(4)-20 mA. Integrated peak/valley picking w/ programmable decay. Output can be temperature or relative radiance
Serial interface	RS-232 interface, bi-directional, baud rate 9,600 to 115,000 bps, for free programming and data transfer
Alarm relays	Two set-points indicated on LCD display
Thermal switch	Monitoring housing temperatue
Power requirements	22...30 VDC or 24 VAC ±10%, 48...400 Hz; <150 mA with 24 VDC
