Rees Scientific’s newly accredited 17025 lab, better known as Presidio Labs is a subsidiary of Rees Scientific
Presidio Labs performs extensive in house analysis to calibrate and certify their probes. Our probes get tested via water baths and high precision SPRT (Standard Platinum Resistance Thermometer). They are tested again by our factory trained field service technicians, who will calibrate the sensors using highly accurate dry blocks. We also use environmental stability chambers to test for temperature and humidity.
