Introducing Truecal from Hach

Laboratory measurements can fail due to a variety of factors, including basic errors in handling and technique, or problems with expired chemistry or inappropriate sampling.

Truecal from Hach reduces variations in results caused by variances in chemistry raw materials. A bar code contains the calibration curve data specific to each lot of chemistry, and automatically updates the calibration curve. With LCK products using the Truecal feature, you’ll have one less thing to worry about during crucial proficiency testing or permit-limit compliance testing.
