The SBIR Model 104i High Resolution Differential Thermometer provides high accuracy temperature measurement without sacrificing ease of use.

Two ultra-stable iProbe temperature sensors are included allowing the instrument to simultaneously display the absolute temperature of two points and also the temperature difference between these two points. Additionally, the 104i thermometer offers four temperature ranges from -40°C to 175°C absolute.

iProbe Advanced Probe Design
The iProbe is an intelligent temperature sensor that can be calibrated independently of the 104i system. To re-calibrate the system you need only exchange the probe with a recently calibrated one. No special equipment is required and there is no down time in the test area.

High Accuracy and Stability
Ultra-stable, highly responsive iProbes are used to provide long term accuracy and repeatability of under 0.010°C.

Battery Operation
Since the netbook supports battery powered operation, the system can be conveniently used without a power supply connection for several hours on a single charge.

Remote Control
The system is equipped with a network server which allows remote monitoring of temperatures from any computer on the network. A client application is provided to allow other PCs to remotely access all features of the 104i Thermometer.

Multi-Function Netbook Computer
The 104i Thermometer features a modern netbook computer attached to an electronics interface module which allows communication with the iProbe.

Real Time Data Logging
The 104i displays both the temperature and a graphical representation of this temperature readout over a period of time.

IEEE Std. 488 Interface (GPIB)
The implementation of the ANSI/IEEE Std. 488.1-1987 allows for computer control of all blackbody, calibration, illuminator, and target wheel functions.

Multiple iProbes
An infinite number of different calibrated iProbes can be plugged into the system and used as the 104i’s calibrated standard(s).

Note: The 104i supports an infinite number of different calibrated iProbes for use as standards, however only 2 can be plugged in and used for calibration purposes at a time.
