• Insert the cuvet with the reacted sample

(# 2) into the instrument. Ensure
that the notch on the cap is positioned
securely into the groove.

• Press READ DIRECT and “SIP” will blink during measurement.

• The instrument directly displays concentration in µg/L of hydra-

zine on the Liquid Crystal Display.

INTERFERENCES

Interference may be caused by:
Highly colored samples
Highly turbid samples
Aromatic amines
