Page 17: Calibration Frequency
Although there is no particular calibration frequency that is correct for all ppm hexane transmitter applications, a calibration frequency of every 6 to 12 months is adequate for most applications. Unless experience in a particular application dictates otherwise, RKI Instruments, Inc. recommends a calibration frequency of every 6 months. -
