To start using the PT12 Precision Thermometer right away, download the manual here and go to page 6, titled “Quick Start / Initial Setup.” There, you’ll find out how to connect a temperature probe, power it up and obtain a reading. We recommend you read through the entire manual to fully understand all of the PT12’s ins and outs, but if you just can’t wait, the quick start section of the manual is, well, a quick start!
RH Systems (RHS) warrants the products it manufactures or distributes to be free of defects in material and workmanship under normal use and service when operated within the specified design limitations for a period of 12 months from date of initial shipment. Under this Warranty, RHS will, at its discretion, repair or replace any component that upon examination by RHS or its duly authorized representatives proves to be defective during the warranty period provided the system is returned to the factory for inspection and repair shipping prepaid. Improper or unauthorized maintenance, storage, repair, or alteration of any kind by personnel other than RHS or its duly authorized representatives may void all warranties. Warranty may also be voided for misuse, neglect, accident, corrosion, and improper installation. This Warranty is exclusive and in lieu of any and all other warranties of merchantability, fitness for a particular purpose, or any other warranty, expressed or implied, and all other liabilities and obligations on the part of RHS. RHS will not be liable for any other claims or damages, either direct, indirect, or consequential arising out of the use of its products.
THERMOtelligent™ Smart-Platinum Resistance Thermometers save you valuable time and decrease the possibility of measurement errors by eliminating the need to change calibration coefficients in the thermometer readout when temperature probes are changed.
Data can be logged automatically to a USB flash drive, or if no drive is detected, data is logged to internal memory and may be copied to a USB drive when inserted at a later time.
Measurements are compensated against drift using four high-precision, high-stability internal reference resistors. During each sampling sequence, the PT12 measures each reference resistor to define the measuring range and accurately determine the unknown values of each of the 12 channels.
At RH Systems, we’re constantly pushing ourselves towards advancing our products and services for a wide range of clients, setting a new standard for accuracy and paving the way for future breakthroughs.
Customer satisfaction is the foundation of our reputation, so we never take a one-size-fits-all approach. We work with you to understand your needs and provide customized solutions that work seamlessly right from the jump.

As a NVLAP accredited laboratory, RH Systems is reassessed to ensure that our quality and practices maintain such standards (NVLAP Laboratory Code 600161-0). The National Institute of Standards and Technology (NIST) administers the National Voluntary Laboratory Accreditation Program (NVLAP), which accredits public and private laboratories based on evaluation of their technical qualifications and competence to carry out specific calibrations or tests.
NVLAP provides an unbiased third-party evaluation and recognition of performance. Accreditation signifies that a laboratory has demonstrated compliance with NVLAP management and technical requirements, including quality systems, personnel, accommodation and environment, test and calibration methods, equipment, measurement tractability, sampling, handling of test and calibration items, and test and calibration reports.
