ADT 286 Multifunction Reference Thermometer Readout Scanner Modules
If you're in need of a precision reference thermometer for your laboratory, then look no further than the Additel 286.
The base unit comes with two precision readout channels that can be used to measure your SPRT. Need to calibrate
RTDs, PRTs, thermistors or thermocouples? Add a scanner module and you now have the ability to measure 10
RTDs, PRTs, or thermistors and 20 thermocouples. Expand up to 82 channels with our unique easy to use scanner
modules. Each 20 channel module is outfitted with our proprietary universal terminals with an industries best cold
junction capability second to none. Utilize the module docked atop the ADT286, or connect remotely with cables
to suit nearly any unique setup/configuration. Additel also has a process module specifically designed to measure
process instrumentation like transmitters and switches. This scanner will also supply loop power for the transmitters.
Designed to make your job easier, the ADT286 has a large sensor library supporting 15 TC types, both standard
and special limits, 18 different thermal resistors, CVD, ITS-90, and a large variety of standard curves for RTDs and
thermistors. The ADT286 is loaded with special applications such as probe calibration, SPRT calibration, chamber
mapping and more. And we continue to add applications on a regular basis!
Available in 25 & 100 Ohm values, users can enjoy improved resistance ratio performance by easily plugging one of our
reference resisters into channel 2 on the new ADT286. Perfect for calibrating your SPRT’s and high end PRT’s.
ADT286-RS Resistance Standards
Automatic Temperature Control and Probe Calibration
The Additel 286 Multifunction Reference Thermometer Readout has preinstalled drivers to control Additel and other
manufacturer’s heat sources. Simply connect to one or more heat sources via a communication cable, Ethernet or
wireless and now it will automatically control to the set point and desired stability. If your heat source is not on the list,
you can easily add the driver yourself so you can run automated calibrations with any heat source.
Now combine the heat source control feature with our probe calibration application and you have a very powerful
automatic calibration solution. The probe calibration app allows you to automatically setup and run calibration routines
with multiple set points and multiple heat sources, collect data, and develop calibration coefcients — all with one device
and without the need of software! Simply place a batch of sensors of any mix and type into your heat source, connect
it to the ADT286, run the probe calibration app and come back to a completed test. All that is left to do is generate
and export all the calibration data. There’s no need to work with complicated software for communication, set up or
coefcient generation. There is no reason to have a calibration technician manually monitor the process and record the
data. This Multifunction Reference Thermometer Readout will do all the work for you.
