UV Equipment Calibration Report
Instructions for Form UV-CAL
General Instructions
This form is to be used to document the calibration of UV sensors, transmittance analyzers and flow meters for
validated UV reactors that are used for compliance with 310 CMR 22.00. The form is to be submitted along with
either form UV-ISA or UV-CDA.
The frequency and procedures for equipment calibration is described on the respective forms.
The form can be used for calibration of instruments for two UV reactors. Facilities with more than two reactors
will require additional forms. The completed form must be signed and submitted to the appropriate MassDEP
th
region by the 10
of the following month. Note: Unless otherwise required by MassDEP, calibration forms must
be submitted for at least the first year that the UV reactor(s) went on-line. After one year, the completed
forms do not need to be submitted to MassDEP. However, completed reports must be kept on site and made
available to MassDEP upon request.

Sensors must be calibrated at least monthly using a reference sensor that is calibrated at least yearly. The form requires that each
reactor, duty sensor and reference sensor have unique IDs. The most recent, and previous, duty sensor calibration dates must be
reported, along with the most recent duty & reference sensor readings (mJ/cm
). The duty sensor to reference sensor ratio is
2
reported and must be ≤ 1.2. If the sensor is out of calibration, the reactor must be taken off line or a calibration factor used and
indicated on form UV-ISA or UV-CDA.

Transmittance analyzers must be calibrated at least weekly for reactors that operate using the ‘calculated dose approach’ (Form
UV-CDA), and at least yearly for reactors that operate using the ‘intensity setpoint approach’ (form UV-ISA). The form requires that
each analyzer and reactor have unique IDs. The most recent, and previous, analyzer calibration dates must be reported along with
the % UV transmittance of both the on-line analyzer and the benchtop spectrophotometer. The difference between the two
readings must be ≤ 2% for the UV reactor to remain on-line.
