Guildline’s Precision Dual Channel Thermometer 5150 provides the best solution for process and status control based on the monitoring of temperatures.  It represents the most cost effective “smart thermometer” available and challenges the most sophisticated bridge type instruments for a fraction of their cost.  In addition to the basic function of extremely accurate temperature measurement, two ‘Form C’ relays provide the means to accomplish process control and monitoring, using programmable contact closure conditions.

Measurements can be made on two independent channels of SPRT’s, PRTs or RTD’s in the ohmic range of 0.25 Ω to 100 Ω and in addition, 2.25 k Ω and 10 k Ω thermistors can be used as sensors for the 5150.  The independent channels allow direct measurement with a relative uncertainty of better than 5ppm to a resolution in temperature to 0.001 °C.  The temperature measurement range is -200°C to 1000°C and the results can be displayed in °C, °F, Kelvin or Ω.

The 5150 will store 500 pairs of readings which are individually identified by date and time and can be transferred to a remote output device via the RS-232C or IEEE 488.2 communication interfaces built into the instrument. A vacuum fluorescent display provides a graphical representation of real-time data and calculated variables, while the information along with probe characteristics can be output via the communication interfaces.  In addition to the main display, both channels have an independent real time LED display for continuous monitoring of temperature.
