CALIBRATION Relative Humidity Calibration The HI 8064 thermohygrometer is factory calibrated, but it is recommended to periodically control the calibration status of the meter. Use the HI 7601 calibration kit composed of a container with two separate chambers, each one equipped with a threaded plug and three envelops containing the necessary salts. Preparing the calibration solutions • Pour approximately 26 cc of distilled water into a glass container.
Calibration procedure • Bring the calibration kit to a temperature of approximately 20 ºC. • Remove the plug from the chamber containing the LiCl solution and insert the probe. • Remove the adhesive sticker which covers the calibration trimmer access holes. • Wait for the reading to stabilize (this will take a few hours) and then turn the "Low humidity trimmer" (the one nearest to the probe connection cable) until the value of 11.1% RH will be displayed on the LCD.
Temperature Calibration The HI 8064 thermohygrometer is factory calibrated and therefore usually it requires no further intervention by the user. If recalibration is desired, proceed as follows: • Remove the adhesive sticker which covers the calibration trimmer access holes. • Insert the probe into a recipient in which air heated at a temperature of 50 ºC has been forced to circulate. • Insert a thermometer with an accuracy of 0.1 ºC into the same recipient. • Read the temperature value on the thermometer.
