Part Number Description
OCT-1 638-93150-01 Permits the automated measurement of up to seven samples, in addition to an on-line flow line.
OCT-1 (second unit) 638-93150-11 Second unit to expand OCT-1. Permits the automated measurement of up to 15 samples,
in addition to an on-line flow line.
TNM-1 638-91065 Permits TN (total nitrogen) measurements.
Nitrogen carrier gas kit 638-42054 High-purity N2 gas (1 ppm max. of CO, CO2, or HC) can be used as the carrier gas.
*Simultaneous use of TNM-1 and this option is not possible.
*The measuring range with this option becomes 0-500 µg/L to 0-100 mg /L for TC and IC both.
Sample adjustment tank 638-42053 Used when bubbles are contained within the sample.
