Can I get 8 thermometer lines that are IR instead of probes to plug into this unit? Also, how long can the wires be for the plugs?

Asked by: AJ AlfaLaval
Thank you for your interest in our products We offered Self Powered IR Thermocouple sensors for example the OS36-K series which provides a type K output . The standard lead wire length is 36 inches . They can be offered in various temperature ranges and field of views. A mini Type K connector GMP-K-M can be added to the stripped lead wires . Please note the IR sensor will have to be evaluated with the meter for suitability due to its high impedance . Details of your application such as Temperature Range both min and max, size and type material of the object that you are measuring, distance of the sensor to object , ambient temperature of sensor etc. will help us determine an appropriate IR sensor for your application Thank you

I had bought a RDXL8CD. How to adjust the temperature offset if example let's say the display temperature reading is 1 degree above the actual measured temperature?

Asked by: Anonymous
From the user's guide on page 47 the CJC value can be accessed for each channel and possibly adjusted. If this does not work or you have questions please contact the Temperature Engineering group at
